Improving Skin Cancer Treatment by Dual Drug Co-Encapsulation into Liposomal Systems-An Integrated Approach towards Anticancer Synergism and Targeted Delivery. Pharmaceutics 2024; 16:1200. [PMID: 39339235 PMCID: PMC11434718 DOI: 10.3390/pharmaceutics16091200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2024] [Revised: 09/05/2024] [Accepted: 09/10/2024] [Indexed: 09/30/2024] Open
Abstract
Skin cancer is a high-incidence complex disease, representing a significant challenge to public health, with conventional treatments often having limited efficacy and severe side effects. Nanocarrier-based systems provide a controlled, targeted, and efficacious methodology for the delivery of therapeutic molecules, leading to enhanced therapeutic efficacy, the protection of active molecules from degradation, and reduced adverse effects. These features are even more relevant in dual-loaded nanosystems, with the encapsulated drug molecules leading to synergistic antitumor effects. This review examines the potential of improving the treatment of skin cancer through dual-loaded liposomal systems. The performed analysis focused on the characterization of the developed liposomal formulations' particle size, polydispersity index, zeta potential, encapsulation efficiency, drug release, and in vitro and/or in vivo therapeutic efficacy and safety. The combination of therapeutic agents such as doxorubicin, 5-fluorouracil, paclitaxel, cetuximab, celecoxib, curcumin, resveratrol, quercetin, bufalin, hispolon, ceramide, DNA, STAT3 siRNA, Bcl-xl siRNA, Aurora-A inhibitor XY-4, 1-Methyl-tryptophan, and cytosine-phosphate-guanosine anionic peptide led to increased and targeted anticancer effects, having relevant complementary effects as well, including antioxidant, anti-inflammatory, and immunomodulatory activities, all relevant in skin cancer pathophysiology. The substantial potential of co-loaded liposomal systems as highly promising for advancing skin cancer treatment is demonstrated.

Colloids Surf B Biointerfaces 2024; 233:113608. [PMID: 37925866 DOI: 10.1016/j.colsurfb.2023.113608] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 10/08/2023] [Accepted: 10/18/2023] [Indexed: 11/07/2023]
Abstract
Antioxidant nutraceuticals can be found in several dietary sources and have been utilized for various medical benefits including health promotion, disease prevention, and support for treatment of acute and/or chronic diseases. Nonetheless, there are some limitations in delivering antioxidants via oral administration such as low solubility and permeability, pH and enzyme degradation, and instability of the compounds along the gastrointestinal tract leading to low bioavailability. In order to tackle these challenges, the utilization of lipid nanoparticles has numerous advantages to the escalating delivery system of antioxidants in nutraceuticals across the gastrointestinal tract barrier. Nowadays, several types of lipid nanoparticles can be used in antioxidant nutraceutical delivery systems through the oral route, namely solid lipid nanoparticles and nanostructured lipid carriers. This review article aims to provide notable information on the importance and applications of lipid nanoparticles in antioxidant delivery systems from nutraceuticals by an oral route. The mechanism in enhancing antioxidant compound transport across the gastrointestinal tract can occur by elevating loading capacity, improving chemical and physical stability, and increasing its bioavailability. To date, lipid nanoparticle vehicles have been developed to improve the delivery of antioxidant compounds to enhance bioavailability via oral routes. Lipid nanoparticles have remarkable benefits in delivering antioxidant nutraceuticals via oral administration. Hence, scale-up and commercialization of antioxidant nutraceutical-loaded lipid nanoparticles have been a potential technology in recent years. Subsequently, several vegetable and natural oils with antioxidant activity can also be utilized for nanoparticle formulation lipid components to increase nutraceuticals' antioxidant properties and bioavailability.

Abstract
The global incidence of oral cancer has steadily increased in recent years and is associated with high morbidity and mortality. Oral cancer is the most common cancer in the head and neck region, and is predominantly of epithelial origin (i.e. squamous cell carcinoma). Oral cancer treatment modalities mainly include surgery with or without radiotherapy and chemotherapy. Though proven effective, chemotherapy has significant adverse effects with possibilities of tumor resistance to anticancer drugs and recurrence. Thus, there is an imperative need to identify suitable anticancer therapies that are highly precise with minimal side effects and to make oral cancer treatment effective and safer. Among the available adjuvant therapies is curcumin, a plant polyphenol isolated from the rhizome of the turmeric plant Curcuma longa. Curcumin has been demonstrated to have anti-infectious, antioxidant, anti-inflammatory, and anticarcinogenic properties. Curcumin has poor bioavailability, which has been overcome by its various analogues and nanoformulations, such as nanoparticles, liposome complexes, micelles, and phospholipid complexes. Studies have shown that the anticancer effects of curcumin are mediated by its action on multiple molecular targets, including activator protein 1, protein kinase B (Akt), nuclear factor κ-light-chain-enhancer of activated B cells, mitogen-activated protein kinase, epidermal growth factor receptor (EGFR) expression, and EGFR downstream signaling pathways. These targets play important roles in oral cancer pathogenesis, thereby making curcumin a promising adjuvant treatment modality. This review aims to summarize the different novel formulations of curcumin and their role in the treatment of oral cancer.

Hot-Melt Extrusion as an Effective Technique for Obtaining an Amorphous System of Curcumin and Piperine with Improved Properties Essential for Their Better Biological Activities. Molecules 2023; 28:molecules28093848. [PMID: 37175257 PMCID: PMC10180276 DOI: 10.3390/molecules28093848] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 04/26/2023] [Accepted: 04/28/2023] [Indexed: 05/15/2023] Open
Abstract
Poor bioavailability hampers the use of curcumin and piperine as biologically active agents. It can be improved by enhancing the solubility as well as by using bioenhancers to inhibit metabolic transformation processes. Obtaining an amorphous system of curcumin and piperine can lead to the overcoming of these limitations. Hot-melt extrusion successfully produced their amorphous systems, as shown by XRPD and DSC analyses. Additionally, the presence of intermolecular interactions between the components of the systems was investigated using the FT-IR/ATR technique. The systems were able to produce a supersaturation state as well as improve the apparent solubilities of curcumin and piperine by 9496- and 161-fold, respectively. The permeabilities of curcumin in the GIT and BBB PAMPA models increased by 12578- and 3069-fold, respectively, whereas piperine's were raised by 343- and 164-fold, respectively. Improved solubility had a positive effect on both antioxidant and anti-butyrylcholinesterase activities. The best system suppressed 96.97 ± 1.32% of DPPH radicals, and butyrylcholinesterase activity was inhibited by 98.52 ± 0.87%. In conclusion, amorphization remarkably increased the dissolution rate, apparent solubility, permeability, and biological activities of curcumin and piperine.

Abstract
Numerous preclinical studies provide evidence that curcumin, a polyphenolic phytochemical extracted from Curcuma longa (turmeric) has neuroprotective, anti-inflammatory and antioxidant properties against various neurological disorders. Curcumin neuroprotective effects have been reported in different animal models of epilepsy, but its potential effect attenuating brain glucose hypometabolism, considered as an early marker of epileptogenesis that occurs during the silent period following status epilepticus (SE), still has not been addressed. To this end, we used the lithium-pilocarpine rat model to induce SE. Curcumin was administered orally (300 mg/kg/day, for 17 days). Brain glucose metabolism was evaluated in vivo by 2-deoxy-2-[18F]Fluoro-D-Glucose ([18F]FDG) positron emission tomography (PET). In addition, hippocampal integrity, neurodegeneration, microglia-mediated neuroinflammation, and reactive astrogliosis were evaluated as markers of brain damage. SE resulted in brain glucose hypometabolism accompanied by body weight (BW) loss, hippocampal neuronal damage, and neuroinflammation. Curcumin did not reduce the latency time to the SE onset, nor the mortality rate associated with SE. Nevertheless, it reduced the number of seizures, and in the surviving rats, curcumin protected BW and attenuated the short-term glucose brain hypometabolism as well as the signs of neuronal damage and neuroinflammation induced by the SE. Overall, our results support the potential adaptogen-like effects of curcumin attenuating key features of SE-induced brain damage.

Abstract
BACKGROUND Due to their plasticity, macrophages exert critical effects on both promoting and suppressing inflammatory processes. Pathologic inflammatory conditions are frequently correlated with dynamic alterations in macrophage activation, with classically activated M1 cells associated with the promotion and maintenance of inflammation and M2 cells being linked to the resolution or smouldering of chronic inflammation. Inflammation deputes a common feature of various chronic diseases and the direct involvement in the insurgence and development of these conditions. Macrophages participate in an autoregulatory loop characterizing the inflammatory process, as they produce a wide range of biologically active mediators that exert either deleterious or beneficial effects during the inflammation. Therefore, balancing the favorable ratios of M1/M2 macrophages can help ameliorate the inflammatory landscape of pathologic conditions. Curcumin is a component of turmeric with many pharmacological properties. OBJECTIVE Recent results from both in-vivo and in-vitro studies have indicated that curcumin can affect polarization and/or functions of macrophage subsets in the context of inflammation-related diseases. There is no comprehensive review of the impact of curcumin on cytokines involved in macrophage polarization in the context of inflammatory diseases. The present review will cover some efforts to explore the underlying molecular mechanisms by which curcumin modulates the macrophage polarization in distant pathological inflammatory conditions, such as cancer, autoimmunity, renal inflammation, stroke, atherosclerosis, and macrophage-driven pathogenesis. RESULTS The accumulation of the findings from in vitro and in vivo experimental studies suggests that curcumin beneficially influences M1 and M2 macrophages in a variety of inflammatory diseases with unfavorable macrophage activation. CONCLUSION Curcumin not only enhances anti-tumor immunity (via shifting M polarization towards M1 phenotype and/or up-regulation of M1 markers expression) but ameliorates inflammatory diseases, including autoimmune diseases (experimental autoimmune myocarditis and Behcet's disease), nephropathy, chronic serum sickness, stroke, and atherosclerosis.

Enhancement of Release and Solubility of Curcumin from Electrospun PEO-EC-PVP Tripolymer-Based Nanofibers: A Study on the Effect of Hydrogenated Castor Oil. ACS OMEGA 2022; 7:37264-37278.

Abstract
This study reveals the state-of-the-art fabrication of a tripolymer-based electrospun nanofiber (NF) system to enhance the release, solubility, and transdermal penetration of curcumin (Cur) with the aid of in situ release of infused castor oil (Co). In this regard, Cur-loaded Co-infused polyethylene oxide (PEO), ethyl cellulose (EC), and polyvinyl pyrrolidone (PVP) tripolymer-based NF systems were developed to produce a hybridized transdermal skin patch. Weight percentages of 1-4% Cur and 3-10% of Co were blended with PEO-EC-PEO and PEO-EC-PVP polymer systems. The prepared NFs were characterized by SEM, TEM, FT-IR analysis, PXRD, differential scanning calorimetry (DSC), and XPS. Dialysis membranes and vertical Franz diffusion cells were used to study the in vitro drug release and transdermal penetration, respectively. The results indicated that maintaining a Cur concentration of 1-3 wt % with 3 wt % Co in both PEO-EC-Co-Cur@PEO and PEO-EC-Co-Cur@PVP gave rise to nanofibers with lowered diameters (144.83 ± 48.05-209.26 ± 41.80 nm and 190.20 ± 59.42-404.59 ± 45.31 nm). Lowered crystallinity observed from the PXRD patterns and the disappearance of exothermic peaks corresponding to the melting point of Cur suggested the formation of an amorphous NF structure. Furthermore, the XPS data revealed that the Cur loading will possibly take place at the inner interface of PEO-EC-Co-PEO and PEO-EC-Co-PVP NFs rather than on the surface. The beneficiary role of Co on the release and dermal penetration of Cur was further confirmed from the respective release data which indicated that PEO-EC-Co-Cur@PEO would lead to a rapid release (4-5 h), while PEO-EC-Co-Cur@PVP would lead to a sustained release over a period of 24 h in the presence of Co. Transdermal penetration of the released Cur was further evidenced with the development of color in the receiver compartment of the diffusion cell. DPPH results further corroborated that a sustained antioxidant activity is observed in the released Cur where the free-radical scavenging activity is intact even after subjecting to an electrospinning process and under extreme freeze-thaw conditions.

Abstract
The present work investigates a blend of jack fruit mucilage (JFM) and okra mucilage (OKM) as promising mucoadhesive carriers for colon-specific delivery of a curcumin (CMN)-loaded mucoadhesive tablet (CMT) formulation. Formulation optimization was performed using central composite design (CCD) to further decipher the effect of varying proportions of the mucoadhesive carriers JFM and OKG on response factors such as drug release (% DR) and mucoadhesive strength (MA). The optimized formulation CMT (F14) demonstrated a favorable 54.35% in vitro release of CMN in 12 h with release kinetics resulting from a zero-order anomalous diffusion mechanism and MA of 34.1733 ± 1.26 g. Accelerated stability testing of CMT (F14) confirmed a shelf life of about 4.7 years. In vivo drug targeting studies performed using rabbit models in order to observe transit behavior (colon-specific delivery) of the dosage form were assessed by fluoroscopic images of the GI tract. Taking the results together, the results confirm that the combination of JFM and OKM could be exploited as an ideal mucoadhesive carrier for effective delivery of macromolecules to the colon.

Abstract
Although curcumin is globally recognized for its health benefits, its clinical application has been restricted by its poor aqueous solubility and stability. To overcome these limitations, nanocarrier-based drug delivery systems (NDS) are one of the most effective approaches being extensively explored over the last few decades to improve curcumin's physicochemical and pharmacological effects. Various NDS could provide productive platforms for addressing the formulation challenge of curcumin, but evidence of such systems has not been summarized. This study aimed to systematically review current evidence of lipid and polymer-based NDS for an oral delivery of curcumin focusing on in vivo models and clinical studies. Among the 48 included studies, 3 studies were randomized controlled clinical trials, while 45 studies were animal models. To date, only five curcumin NDS have been studied in healthy volunteers: γ-cyclodextrin, phytosome, liposome, microemulsion and solid dispersion, while most curcumin NDS have been studied in animal models. Most included studies found that NDS could increase oral bioavailability of curcumin as compared to free curcumin. In conclusion, this systematic review showed evidence of the positive effect of NDS for enhancement of oral bioavailability of curcumin. EXECUTIVE SUMMARY: Curcumin is globally recognized for its health benefits, but its clinical application has been limited by its poor aqueous solubility and stability, which causes poor absorption in the gastrointestinal tract (GI tract) via oral administration. Nanocarrier-based drug delivery systems (NDS) are considered as a productive platform to solve the formulation challenge of curcumin, but evidence of such systems has not been summarized. This study aimed to systematically review current evidence of lipid and polymer-based NDS for an oral delivery of curcumin focusing on in vivo models and clinical studies. Overall, most studies found that all studied NDS could increase the absorption of curcumin as compared to free curcumin. Curcumin was rapidly absorbed and exhibited a long residence time after oral administration of curcumin NDS. In summary, this systematic review showed positive impacts of NDS for enhancement of oral absorption of curcumin.

Recent Advances in the Local Drug Delivery Systems for Improvement of Anticancer Therapy. Curr Drug Deliv 2021; 19:560 - 586. [PMID: 34906056 DOI: 10.2174/1567201818666211214112710] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 09/29/2021] [Accepted: 10/12/2021] [Indexed: 11/22/2022]
Abstract
The conventional anticancer chemotherapies not only cause serious toxic effects, but also produce resistance in tumor cells exposed to long-term therapy. Usually, the killing of metastasized cancer cells requires long-term therapy with higher drug doses, because the cancer cells develop resistance due to the induction of poly-glycoproteins (P-gps) that act as a transmembrane efflux pump to transport drugs out of the cells. During the last few decades, scientists have been exploring new anticancer drug delivery systems such as microencapsulation, hydrogels, and nanotubes to improve bioavailability, reduce drug-dose requirement, decrease multiple drug resistance, and to save normal cells as non-specific targets. Hopefully, the development of novel drug delivery vehicles (nanotubes, liposomes, supramolecules, hydrogels, and micelles) will assist to deliver drug molecules at the specific target site and reduce the undesirable side effects of anticancer therapies in humans. Nanoparticles and lipid formulations are also designed to deliver small drug payload at the desired tumor cell sites for their anticancer actions. This review will focus on the recent advances in the drug delivery systems, and their application in treating different cancer types in humans.

[PMID: 34597726 DOI: 10.1016/j.ijpharm.2021.121124] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 09/17/2021] [Accepted: 09/18/2021] [Indexed: 12/20/2022]
Abstract
Curcumin and chloramphenicol are drugs with different solubility properties in physiological conditions due to their hydrophobic and hydrophilic structure, respectively. In this work, sodium alginate-cellulose nanofibers (SA-CNF) based inks loaded with curcumin and/or chloramphenicol have been developed for syringe extrusion 3D printing technology. Printability and shape fidelity of the drug-loaded inks were analyzed through rheological characterization. Suitable drug-loaded inks were 3D printed showing shape fidelity, and samples were either freeze-dried or crosslinked with Ca2+ and air-dried to achieve functional pharmaceutical forms with different morphological characteristics. In vitro drug delivery tests were carried out from the resulted forms and it was observed that the release performed faster in freeze-dried than in Ca2+ crosslinked/air-dried ones for all cases, resulting in two different methods for controlling drug delivery over time. The differences in aqueous solubility of the drugs, the different CNF content of the inks and the surface area of the samples also played an important role during drug delivery, involving strategies to control the release over an extended duration.

Mechanistic Insight into the Effects of Curcumin on Neuroinflammation-Driven Chronic Pain. Pharmaceuticals (Basel) 2021; 14:ph14080777.

Abstract
Chronic pain is a persistent and unremitting condition that has immense effects on patients' quality of life. Studies have shown that neuroinflammation is associated with the induction and progression of chronic pain. The activation of microglia and astrocytes is the major hallmark of spinal neuroinflammation leading to neuronal excitability in the projection neurons. Excessive activation of microglia and astrocytes is one of the major contributing factors to the exacerbation of pain. However, the current chronic pain treatments, mainly by targeting the neuronal cells, remain ineffective and unable to meet the patients' needs. Curcumin, a natural plant product found in the Curcuma genus, improves chronic pain by diminishing the release of inflammatory mediators from the spinal glia. This review details the role of curcumin in microglia and astrocytes both in vitro and in vivo and how it improves pain. We also describe the mechanism of curcumin by highlighting the major glia-mediated cascades in pain. Moreover, the role of curcumin on inflammasome and epigenetic regulation is discussed. Furthermore, we discuss the strategies used to improve the efficacy of curcumin. This review illustrates that curcumin modulating microglia and astrocytes could assure the treatment of chronic pain by suppressing spinal neuroinflammation.

Abstract
The present study aims to develop curcumin-loaded nanostructured lipid carriers (CUR-NLCs) and investigate their neuroprotective effects in lipopolysaccharide (LPS)-induced depression and anxiety model. Nanotemplate engineering technique was used to prepare CUR-NLCs with Compritol 888 ATO and oleic acid as solid and liquid lipid, respectively. Poloxamer 188, Tween 80 and Span 80 were used as stabilizing agents for solid-liquid lipid core. The physicochemical parameters of CUR-NLCs were determined followed by in vitro drug release and in vivo neuroprotective activity in rats. The optimized CUR-NLCs demonstrated nanometric particle size of 147.8 nm, surface charge of -32.8 mV and incorporation efficiency of 91.0%. CUR-NLCs showed initial rapid followed by a sustained drug release reaching up to 73% after 24 h. CUR-NLCs significantly elevated struggling time and decreased immobility time in forced swim and tail suspension tests. A substantial increase in time spent and number of entries into the light and open compartments was observed in light-dark box and elevated plus maze models. CUR-NLCs improved the tissue architecture and suppressed the expression of p-NF-κB, TNF-α and COX-2 in brain tissues from histological and immunohistochemical analysis. CUR-NLCs improved the neuroprotective effect of curcumin and can be used as a potential therapeutics for depression and anxiety.

Abstract
At present, saccharides as hydrophilic matrixes, have been gradually used in amorphous solid dispersions (ASD) for dispersing poorly water-soluble drugs without surfactants. In this study, an amorphous chitosan oligosaccharide (COS) was applied as a water-soluble matrix to form surfactant-free ASD via the ball milling to vitrify quercetin (QUE) and enhance the dissolution and bioavailability. Solid-state characterization (DSC, XRPD, FTIR, SEM and PLM) and physical stability assessments verified that the prepared ASDs showed excellent physical stability with complete amorphization due to potential interactions between QUE and COS. In vitro sink dissolution tests suggested all QUE-COS ASDs (w:w, 1:1, 1:2 and 1:4) significantly enhanced the dissolution rate of QUE. Meanwhile, in vitro non-sink dissolution exhibited that the maximum supersaturated concentration ranged from 112.62 to 138.00 µg/mL for all QUE-COS ASDs, which was much higher than that of pure QUE. Besides, the supersaturation of QUE-COS ASD kept for at least 24 h. In rat pharmacokinetics, the oral bioavailability of QUE-COS ASDs showed 1.64 ∼ 2.25 times increase compared to the pure QUE (p < .01). Hence, the present study confirms the amorphous COS could be applied as a promising hydrophilic matrix in QUE-COS ASDs for enhancing dissolution performance and bioavailability of QUE.

Abstract
Background: Therapeutic activities of curcumin (CUR) via oral administration are hampered by the lack of bioavailability due to its poor water solubility and rapid degradation in GI tract. Materials & methods: This preliminary study developed CUR micelle-eudragit S100 (EUD) dry powder (CM-EDP) spray-dried formulations. Poloxamer 407 was used as a micelle-forming agent and EUD as an entrapping matrix for protection over hydrolysis and enzymes in the GI tract. Results: The morphology of CM-EDP showed agglomeration with cratering on the surface of particles. Differential thermal analysis and x-ray diffractometry data exhibited evidence that CUR was converted into amorphous solid. An increased concentration of micelle-forming and dispersion matrix polymers resulted in a high fraction of drug being converted into the amorphous state. A significant increase in dissolution by 7–10 times was achieved compared with that of raw CUR. Conclusion: The present study disclosed the CM-EDP potency for future development of CUR oral formulation. Curcumin (CUR) is a natural compound that shows several pharmacological activities, including anti-inflammatory and potential actions against Parkinson’s and Alzheimer’s. However, several drawbacks need to be addressed its application as a therapeutic agent via oral administration. These drawbacks include its poor water solubility and rapid degradation in the GI tract. The present study developed CUR micelle-eudragit S100 (EUD) dry powder formulation involving poloxamer 407 as solubilizing agent and EUD as entrapping matrix for protection in acidic environments and the enzymes in the GI tract. The final product is in the form of dry powder, which showed potency in enhancing CUR absorption following oral administration.

Abstract
The nutraceutical system of curcumin-piperine in 2-hydroxypropyl-β-cyclodextrin was prepared by using the kneading technique. Interactions between the components of the system were defined by X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR). Application of hydroxypropyl-β-cyclodextrin as a carrier-solubiliser improved solubility of the curcumin-piperine system, its permeability through biological membranes (gastrointestinal tract, blood-brain barrier) as well as the antioxidant, antimicrobial and enzyme inhibitory activities against acetylcholinesterase and butyrylcholinesterase.

Abstract
BACKGROUND Although curcumin has been demonstrated to be beneficial in treating various diseases, its low solubility, chemical stability and bioavailability limit its application, especially in cancer therapy. METHODS Solid dispersions have been utilized in the last few decades to improve the bioavailability and stability of curcumin. RESULTS However, there is a lack of summaries and classifications of the methods for preparing curcumin with this technology. The current review aims to overview the strategies used to develop solid dispersions containing curcumin for improving drug delivery. The classification of techniques for creating solid dispersions for curcumin was summarized, including systems for protecting curcumin degradation despite its chemical stability. The applications of advanced nanotechnologies in recent studies of solid dispersions were also discussed to explain the roles of nanoparticles in formulations. CONCLUSION This overview of recent developments in formulating solid dispersions for improving curcumin bioavailability will contribute to future studies of curcumin for clinical development.

Abstract
This study deals with the synthesis of a gliadin-stabilized gold quantum cluster (AuQC) for the encapsulation of curcumin (CUR) and its targeted delivery to the cancer cell. CUR is an anticancer drug containing a hydrophobic polyphenol derived from the rhizome of Curcuma longa. The utilization of CUR in cancer treatment is limited because of suboptimal pharmacokinetics and poor bioavailability at the tumor site. In order to improve the bioavailability of CUR, we have encapsulated it into AuQCs stabilized by a proline-rich protein gliadin because proline-rich protein has the ability to bind a hydrophobic drug CUR. The encapsulation of CUR into the hydrophobic cavity of the protein was confirmed by various spectroscopic techniques. Compared to CUR alone, the encapsulated CUR was stable against degradation and showed higher pH stability up to pH 8.5. The encapsulation efficiency of CUR in AuQCs was calculated as 98%, which was much higher than the other reported methods. In vitro drug release experiment exhibited a controlled and pH-dependent CUR release over a period of 60 h. The encapsulated CUR-QCs exhibited less toxicity in the normal cell line (L929) and high toxicity in breast cancer (MDA-MB239). Thus, it can be used as a potential material for anticancer therapy and bioimaging.

Abstract
BACKGROUND Palmitic acid (PA) is a common saturated fatty acid that induces apoptosis in various types of cells, including testicular Leydig cells. There is evidence suggesting that PA is increased in patients with obesity and that PA-induced cell apoptosis may play an important role in obesity-related male infertility. Curcumin, a natural polyphenol, has been reported to exert cytoprotective effects in various cell types. However, the cytoprotective effect of curcumin against PA-induced apoptosis in Leydig cells remains unknown. Therefore, the current study was performed to investigate the protective effects of curcumin in response to PA-induced toxicity and apoptosis in murine Leydig tumor cell line 1 (MLTC-1) cells and explore the mechanism underlying its anti-apoptotic action. METHODS MLTC-1 cells were cultured in Roswell Park Institute-1640 medium and divided into five groups. First four groups were treated with 50-400 μM PA, 400 μM PA + 5-40 μM curcumin, 400 μM PA + 500 nM 4-phenylbutyric acid (4-PBA, an endoplasmic reticulum (ER) stress inhibitor), and 500 nM thapsigargin (TG, an ER stress inducer) + 20 μM curcumin, respectively, followed by incubation for 24 h. Effects of PA and/or curcumin on viability, apoptosis, and ER stress in MLTC-1 cells were then determined by cell proliferation assay, flow cytometry, and western blot analysis. The fifth group of MLTC-1 cells was exposed to 400 μM of PA and 5 IU/mL of human chorionic gonadotropin (hCG) for 24 h in the absence and presence of curcumin, followed by measurement of testosterone levels in cell-culture supernatants by enzyme-linked immunosorbent assay (ELISA). Rats fed a high-fat diet (HFD) were treated with or without curcumin for 4 weeks, and the testosterone levels were detected by ELISA. RESULTS Exposure to 100-400 μM PA reduced cell viability, activated caspase 3, and enhanced the expression levels of the apoptosis-related protein BCL-2-associated X protein (BAX) and ER stress markers glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in MLTC-1 cells. Treating cells with 500 nM 4-PBA significantly attenuated PA-induced cytotoxicity through inhibition of ER stress. Curcumin (20 μM) significantly suppressed PA- or TG-induced decrease in cell viability, caspase 3 activity, and the expression levels of BAX, CHOP, and GRP78. In addition, treating MLTC-1 cells with 20 μM curcumin effectively restored testosterone levels, which were reduced in response to PA exposure. Similarly, curcumin treatment ameliorated the HFD-induced decrease in serum testosterone level in vivo. CONCLUSIONS The present study suggests that PA induces apoptosis via ER stress and curcumin ameliorates PA-induced apoptosis by inhibiting ER stress in MLTC-1 cells. This study suggests the application of curcumin as a potential therapeutic agent for the treatment of obesity-related male infertility.

Abstract
The objective of the present study was to investigate the effect of partially hydrolyzed ginsenoside on the physicochemical properties and in vitro release of curcumin from phospholipid-based nanostructured lipid carrier (NLC). NLC formulas modified with partially hydrolyzed ginsenoside (NLC-PG) were prepared with different amounts of ginsenoside using the conventional hot-melt method. The average particle size of curcumin-loaded NLC-PG ranged from 150 to 200 nm, and polydispersity index was in the range of 0.101-0.177, indicating monodispersed particle size distribution. Optical microscopy showed no sedimentation or recrystallization of curcumin even at 10,000 μg/ml concentration as NLC-PG in distilled water, indicating significantly enhanced solubility. TEM image showed that the nanoparticles were monodispersed with a multilayered core/shell structure. X-ray diffraction and FTIR spectroscopy showed that curcumin was amorphous in the NLC-PG, and there was no interaction between curcumin and the excipients. In vitro release study using simulated gastric/intestinal fluid media revealed that the release rate (Jss) of curcumin from the NLC-PG increased as a function of the ginsenoside content in the lipid carrier. Moreover, the Jss of curcumin kept gradually increasing in the presence of lipase, whereas in the presence of viscozyme, it sharply increased until the ginsenoside content reached 9.09% and subsequently plateaued. Partially hydrolyzed ginsenoside increased the Jss of curcumin from curcumin-loaded NLC-PG and therefore may be useful for improving the bioavailability of curcumin.

Abstract
Curcumin (CUR) has gained increasing interest worldwide due to multiple biological activities. However, the therapeutic application remains limited because of its low aqueous solubility, intestinal metabolism and poor membrane permeability. In present study, an excipient-free CUR solid dispersion co-formed with piperine (PIP), the absorption enhancer involving metabolism-permeability, was successfully prepared by melting and quench cooling (co-amorphous CUR-PIP). The co-amorphous CUR-PIP exhibited superior performance in non-sink dissolution compared with crystalline and amorphous CUR, and showed physically stable at least 3 months, attributing to the strong molecular interactions between CUR and PIP as evaluated by FTIR spectra. Furthermore, the combination of PIP with CUR in the co-amorphous formulation could inhibit the glucuronidation of CUR, as exhibited in the in vitro assay of rat intestinal microsomes. The co-amorphous CUR-PIP would also exhibit higher gastrointestinal membrane permeability of CUR, as confirmed by Papp of CUR in Caco-2 model. After administration of co-amorphous CUR-PIP, the AUC of CUR significantly increased by 2.16- and 1.92-fold those in crystalline and amorphous CUR, respectively. This study demonstrates that the developed co-amorphous CUR-PIP can enhance the bioavailability of CUR by increasing its dissolution, inhibiting metabolic processes, and facilitating membrane permeability.

Abstract
Effective drug delivery is one of the most important issues associated with the administration of therapeutic agents that have low oral bioavailability. Curcumin is an active ingredient in the turmeric plant, which has low oral bioavailability due to its poor aqueous solubility. One strategy that has been considered for enhancing the aqueous solubility, and, thus, its oral bioavailability, is the use of chitosan as a carrier for curcumin. Chitosan is a biodegradable and biocompatible polymer that is relatively water-soluble. Therefore, various studies have sought to improve the aqueous solubility of chitosan. The use of different pharmaceutical excipients and formulation strategies has the potential to improve aqueous solubility, formulation processing, and the overall delivery of hydrophobic drugs. This review focuses on various methods utilized for chitosan-based delivery of curcumin.

Surfactant-free solid dispersion of BCS class IV drug in an amorphous chitosan oligosaccharide matrix for concomitant dissolution in vitro - permeability increase. Eur J Pharm Sci 2019; 130:147-155. [PMID: 30699368 DOI: 10.1016/j.ejps.2019.01.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Revised: 01/22/2019] [Accepted: 01/25/2019] [Indexed: 02/06/2023]
Abstract
Saccharides have been applied as a water-soluble matrix for dispersing hydrophobic drugs homogeneously without the need to use surfactants in amorphous solid dispersions (ASD). Up to now, concomitant permeability improvement of BCS Class IV drug by such matrices have not been much appreciated. Herein, an amorphous chitosan oligosaccharide (COS) was used as matrix to prepare surfactant-free ASD of BCS class IV drug by the ball milling method, with curcumin (CUR) as a model drug. The DSC, XRPD, FTIR and physical stability experiments indicated that CUR was in an amorphous state with high physical stability and exhibited potential interactions with COS in the ASD. Non-sink dissolution in vitro studies showed the maximum dissolution concentration of all CUR-COS ASD (CUR and COS at weight ratios of 1:1, 1:2 and 1:4) reached ranging from 97.85 to 101.21 μg/mL, far above that of pure CUR. The supersaturated concentration remained for at least 24 h under non-sink condition. Caco-2 cell model revealed that, compared to the pure CUR group, the apparent permeability coefficients were increased by 1.72-4.44-fold in all three CUR-COS ASD, which was mainly attributed to opening the tight junctions of Caco-2 cells by COS. The pharmacokinetic study showed that all CUR-COS ASD groups exhibited significant enhancements in AUC0-∞, with 1.55-3.01-fold that of pure CUR (p < 0.01). Tmax of CUR was shortened after oral administration of all three ASD. The current study demonstrates the amorphous COS could be used as a promising matrix in ASD for enhancing the oral bioavailability of BCS class IV drug by improving dissolution behavior and membrane permeability.

Abstract
The purpose of our article is to assess the current understanding of Indian spice, curcumin, against amyloid-β (Aβ)-induced toxicity in Alzheimer's disease (AD) pathogenesis. Natural products, such as ginger, curcumin, and gingko biloba have been used as diets and dietary supplements to treat human diseases, including cancer, cardiovascular, respiratory, infectious, diabetes, obesity, metabolic syndromes, and neurological disorders. Products derived from plants are known to have protective effects, including anti-inflammatory, antioxidant, anti-arthritis, pro-healing, and boosting memory cognitive functions. In the last decade, several groups have designed and synthesized curcumin and its derivatives and extensively tested using cell and mouse models of AD. Recent research on Aβ and curcumin has revealed that curcumin prevents Aβ aggregation and crosses the blood-brain barrier, reach brain cells, and protect neurons from various toxic insults of aging and Aβ in humans. Recent research has also reported that curcumin ameliorates cognitive decline and improves synaptic functions in mouse models of AD. Further, recent groups have initiated studies on elderly individuals and patients with AD and the outcome of these studies is currently being assessed. This article highlights the beneficial effects of curcumin on AD. This article also critically assesses the current limitations of curcumin's bioavailability and urgent need for new formulations to increase its brain levels to treat patients with AD.

Abstract
SHetA2 is a novel anticancer drug with poor aqueous solubility. In formal toxicological studies, Kolliphor HS 15 was used as a solubilizing agent to increase the oral bioavailability of SHetA2. The purpose of this study was to formulate SHetA2 and Kolliphor HS 15 as solid powders to facilitate their filling in hard gelatin capsules for clinical trials. Two manufacturing processes, ultra-rapid freeze-drying (URFD) and spray freeze drying (SFD), were employed to fabricate solid powders of SHetA2-Kolliphor HS 15 and trehalose. The morphology, size, flowability, and compressibility of URFD-SHetA2 and SFD-SHetA2 powders were characterized. The crystallinity and apparent maximum solubility of SHetA2 in both powders were also determined. SFD-SHetA2 powders were spherical in shape, small, and with a wide size distribution while the URFD-SHetA2 powders were irregularly shaped and big but with a narrower distribution. DSC and XRD analyses indicated that SHetA2 was mostly amorphous in both powders. The flow of both powders was categorized as "good" (angle of repose < 35°). The uniformity of drug content in URFD-SHetA2 powders was more variable than that in SFD-SHetA2 powders. The solubility profile of SHetA2 in both powders SGF exhibited a transient supersaturation "spring effect" due to the drug's amorphousness followed by extended supersaturation "parachute effect" at approximately 6 μg/ml for both powders compared to 0.02 ± 0.01 μg/ml for unprocessed drug. In conclusion, both URFD and SFD formed solid SHetA2 Kolliphor powders that are possible formulation candidates to be filled in hard gelatin capsules for clinical trials.

Abstract
Curcumin (CRC) has been widely used as a therapeutic agent for various drug delivery applications. In this work, we focused on the applicability of CRC as a nanodrug delivery agent for doxorubicin hydrochloride (DOX) (commercially known as Adriamycin) coated with poly(ethylene glycol) (PEG) as an effective therapeutic strategy against multidrug-resistant cancer cells. The developed PEG-coated CRC/DOX nanoparticles (NPs) (PEG-CRC/DOX NPs) were well localized within the resistant cancer cells inducing apoptosis confirmed by flow cytometry and DNA fragmentation assays. The PEG-CRC/DOX NPs suppressed the major efflux proteins in DOX-resistant cancer cells. The in vivo biodistribution studies on HCT-8/DOX-resistant tumor xenograft showed improved bioavailability of the PEG-CRC/DOX NPs, and thereby suppressed tumor growth significantly compared to the other samples. This study clearly shows that curcumin nanoparticles could deliver DOX efficiently into the multidrug-resistant cancer cells to have potential therapeutic benefits.

Abstract
Despite the promising biological and antioxidant properties of curcumin, its medical applications are limited due to poor solubility in water and low bioavailability. Polymeric nanoparticles (NPs) adapted to oral delivery may overcome these drawbacks. Properties such as particle size, zeta potential, morphology and encapsulation efficiency were assessed. Then, the possibility of storing these NPs in a solid-state form obtained by freeze-drying, in vitro curcumin dissolution and cytocompatibility towards intestinal cells were evaluated. Curcumin-loaded Eudragit® RLPO (ERL) NPs showed smaller particle diameters (245 ± 2 nm) and better redispersibility after freeze-drying than either poly(lactic-co-glycolic acid) (PLGA) or polycaprolactone (PCL) NPs. The former NPs showed lower curcumin encapsulation efficiency (62%) than either PLGA or PCL NPs (90% and 99%, respectively). Nevertheless, ERL NPs showed rapid curcumin release with 91 ± 5% released over 1 h. The three curcumin-loaded NPs proposed in this work were also compatible with intestinal cells. Overall, ERL NPs are the most promising vehicles for increasing the oral bioavailability of curcumin.

Abstract
CONTEXT Curcumin (CUR) is a promising drug candidate based on its broad bioactivities and good antitumor effect, but the application of CUR is potentially restricted because of its poor solubility and bioavailability. OBJECTIVE This study aims at developing a simple and effective drug delivery system for CUR to enhance its solubility and bioavailability thus to improve its antitumor efficacy. MATERIALS AND METHODS Curcumin nanosuspensions (CUR-NSps) were prepared by precipitation-ultrasonication method using mPEG2000-DSPE and soybean lecithin as a combined stabilizer. RESULTS CUR-NSps with a high drug payload of 67.07% were successfully prepared. The resultant CUR-NSps had a mean particle size of 186.33 ± 2.73 nm with a zeta potential of -19.00 ± 1.31 mV. In vitro cytotoxicity assay showed that CUR-NSps exhibited enhanced cytotoxicity compared to CUR solution. The pharmacokinetics results demonstrated that CUR-NSps exhibited a significantly greater AUC0-24 and prolonged MRT compared to CUR injections after intravenous administration. In the biodistribution study, CUR-NSps demonstrated enhanced biodistribution compared with CUR injections in liver, spleen, kidney, brain, and tumor. The CUR-NSps also showed improved antitumor therapeutic efficacy over the injections (70.34% versus 40.03%, p < 0.01). CONCLUSIONS These results suggest that CUR-NSps might represent a promising drug formulation for intravenous administration of CUR for the treatment of cancer.

Abstract
The development of novel combination anticancer drug delivery systems is an important step to improve the effectiveness of anticancer treatment in metastatic breast cancer and to overcome increased toxicity of the currently used combination treatments. The aim of this study was to assess efficient targeting, therapeutic efficacy, and bioavailability of a combination of drugs (curcumin and α-tocopheryl succinate) loaded polystyrene–polysoyaoil–diethanol amine nanoparticles. Polystyrene–polysoyaoil–diethanol amine nanoparticles encapsulating two drugs, individually or in combination, were prepared by double-emulsion solvent evaporation method, resulting in particle size smaller than 250 nm with a surface negative charge between −30 and −40 mV. Entrapment efficiency of curcumin and α-tocopheryl succinate in the epigallocatechin gallate–conjugated dual-drug-loaded nanoparticles was found to be 68% and 80%, respectively. The release kinetics of curcumin and α-tocopheryl succinate from the nanoparticles exhibited a gradual and continuous profile followed by an initial burst behavior with a release over 20 days in vitro. Next, we have investigated the anticancer activity of nanoparticles encapsulating both the drugs and individually drug in human breast cancer cells (MDA-MB-231) using double-staining-based cell death analysis, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assessment of cytotoxicity and flow cytometer. In vitro cytotoxicity studies revealed that epigallocatechin gallate–α-tocopheryl succinate/curcumin–polystyrene–polysoyaoil–diethanol amine nanoparticles are more potent than the corresponding α-tocopheryl succinate/curcumin–polystyrene–polysoyaoil–diethanol amine nanoparticles and their single-drug-loaded forms and show a synergistic and breast tumor targeting function. Thus, here, we propose epigallocatechin gallate–conjugated curcumin and α-tocopheryl succinate–loaded polystyrene–polysoyaoil–diethanol amine nanoparticles which effectively inhibit tumor growth and reduce toxicity compared to single-drug chemotherapy.

Abstract
Skin cancer is one of the most widely prevalent cancer types with over expression of multiple oncogenic signaling molecules including STAT3. Curcumin is a natural compound with effective anti-cancer properties. The objective of this work was to investigate the liposomal co-delivery of curcumin and STAT3 siRNA by non-invasive topical iontophoretic application to treat skin cancer. Curcumin was encapsulated in cationic liposomes and then complexed with STAT3 siRNA. The liposomal nanocomplex was characterized for particle size, zeta-potential, drug release and stability. Human epidermoid (A431) cancer cells were used to study the cell uptake, growth inhibition and apoptosis induction of curcumin-loaded liposome-siRNA complex. Topical iontophoresis was applied to study the skin penetration of nanocomplex in excised porcine skin model. Results showed that curcumin-loaded liposome-siRNA complex was rapidly taken up by cells preferentially through clathrin-mediated endocytosis pathway. The co-delivery of curcumin and STAT3 siRNA using liposomes resulted in significantly (p < .05) greater cancer cell growth inhibition and apoptosis events compared with neat curcumin and free STAT3 siRNA treatment. Furthermore, topical iontophoresis application enhanced skin penetration of nanocomplex to penetrate viable epidermis. In conclusion, cationic liposomal system can be developed for non-invasive iontophoretic co-delivery of curcumin and siRNA to treat skin cancer.

Abstract
BACKGROUND Nanosuspension is one of the most promising strategies to improve the oral bioavailability of insoluble drugs. The existing techniques applied to produce nanosuspensions are classified as "bottom-up" or "top-down" methods, or a combination of both. Curcumin (CUR), a Biopharmaceutics Classification System (BCS) class IV substance, is a promising drug candidate in view of its good bioactivity, but its use is limited due to its poor solubility and permeability. In the present study, CUR nanosuspensions were developed to enhance CUR oral bioavailability using a cost-effective method different from conventional techniques. RESULTS The physicochemical properties of CUR nanosuspensions were characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM). The crystalline state of CUR in different nanosuspensions analyzed using differential scanning calorimeter (DSC) and X-ray diffraction analysis (PXRD) confirmed its amorphous state. In vitro dissolution degree of the prepared CUR nanosuspensions using TPGS or Brij78 as stabilizer was greatly increased. Pharmacokinetic studies demonstrated that the oral bioavailability of CUR was increased 3.18 and 3.7 times after administration of CUR/TPGS nanosuspensions or CUR/Brij78 nanosuspensions, when compared with the administration of CUR suspension. CONCLUSIONS CUR nanosuspensions produced by our cost-effective method could improve its oral bioavailability. In addition, the low-cost and time-saving method reported here is highly suitable for a fast and inexpensive preparation.

Abstract
More than 230,000 diagnosed cases of invasive breast cancer in women was estimated in 2014 and an expected 40,000 deaths attributed to the aggressive carcinoma. An effective approach to diminish the morbidity and mortality of breast cancer is the development of chemopreventive and chemotherapeutic agents. Nutraceuticals have demonstrated their ability to proficiently halt carcinogenesis. The administration of natural compounds able to effectively serve as chemoprevention and chemotherapeutics without causing harm or adverse effects is imperative. Curcumin derived from the rhizome of Curcuma longa L., is a common spice of India, used for centuries because of its medicinal properties. The main component of curcumin possesses a wide range of biological activities; anti-proliferative, anti-inflammatory, and apoptotic characteristics modulated through the inactivation of pathways such as EGK and Akt/mTOR. In addition, curcumin alters the expression of cytokines, transcription factors, and enzymes involved in cell vitality. The in vivo application of curcumin in breast cancer is hindered by its limited bioavailabiity. The synthesis of curcumin analogues and delivery via nanoparticles has demonstrated enhanced bioavailability of curcumin in the malignancy. This review focuses on recent developments in the use of curcumin, curcumin analogues, and novel delivery systems as a preventive and therapeutic method for breast cancer.

Abstract
The concept of using phytochemicals has ushered in a new revolution in pharmaceuticals. Naturally occurring polyphenols (like curcumin, morin, resveratrol, etc.) have gained importance because of their minimal side effects, low cost and abundance. Curcumin (diferuloylmethane) is a component of turmeric isolated from the rhizome of Curcuma longa. Research for more than two decades has revealed the pleiotropic nature of the biological effects of this molecule. More than 7000 published articles have shed light on the various aspects of curcumin including its antioxidant, hypoglycemic, anti-inflammatory and anti-cancer activities. Apart from these well-known activities, this natural polyphenolic compound also exerts its beneficial effects by modulating different signalling molecules including transcription factors, chemokines, cytokines, tumour suppressor genes, adhesion molecules, microRNAs, etc. Oxidative stress and inflammation play a pivotal role in various diseases like diabetes, cancer, arthritis, Alzheimer's disease and cardiovascular diseases. Curcumin, therefore, could be a therapeutic option for the treatment of these diseases, provided limitations in its oral bioavailability can be overcome. The current review provides an updated overview of the metabolism and mechanism of action of curcumin in various organ pathophysiologies. The review also discusses the potential for multifunctional therapeutic application of curcumin and its recent progress in clinical biology.
