Pharmaceutics 2022; 14:pharmaceutics14061218. [PMID: 35745795 PMCID: PMC9229590 DOI: 10.3390/pharmaceutics14061218] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 06/03/2022] [Accepted: 06/06/2022] [Indexed: 02/06/2023] Open
Abstract
The objective of this study was to fabricate and evaluate a pH sensitive cross-linked polymeric network through the free radical polymerization technique for the model drug, cyclophosphamide, used in the treatment of non-Hodgkin’s lymphoma. The Hydrogels were prepared using a polymeric blend of agarose, Pluronic acid, glutaraldehyde, and methacrylic acid. The prepared hydrogels were characterized for drug loading (%), swelling pattern, release behavior, the ingredient’s compatibility, structural evaluation, thermal integrity, and toxicity evaluation in rabbits. The new polymer formation was evident from FTIR findings. The percentage loaded into the hydrogels was in the range of 58.65–75.32%. The developed hydrogels showed significant differences in swelling dynamics and drug release behavior in simulated intestinal fluid (SIF) when compared with simulated gastric fluid (SGF). The drug release was persistent and performed in a controlled manner for up to 24 h. A toxicity study was conducted on white albino rabbits. The developed hydrogels did not show any signs of ocular, skin, or oral toxicity; therefore, these hydrogels can be regarded as safe and potential carriers for controlled drug delivery in biomedical applications.

Abstract
Self-assembled cylindrical aggregates made of amphiphilic molecules emerged almost 40 years ago. Due to their length up to micrometers, those particles display original physico-chemical properties such as important flexibility and, for concentrated samples, a high viscoelasticity making them suitable for a wide range of industrial applications. However, a quarter of century was needed to successfully take advantage of those improvements towards therapeutic purposes. Since then, a wide diversity of biocompatible materials such as polymers, lipids or peptides, have been developed to design self-assembling elongated drug nanocarriers, suitable for therapeutic or diagnostic applications. More recently, the investigation of the main forces driving the unidirectional growth of these nanodevices allowed a translation toward the formation of pure nanodrugs to avoid the use of unnecessary side materials and the possible toxicity concerns associated.

Abstract
Diosgenin (DG) isolated from yam roots revealed various bioactivities and applications as drug carrier. In the present study, a conjugate of DG with cytarabine (Ara-C) was used to prepare the self-assembled nanoparticles (NPs) of DG-Ara-C by a nanoprecipitation method. Dynamic light scattering (DLS) as well as transmission electron microscopy (TEM) were employed to analyze the size and the morphology of NPs, respectively. The stability and absorption of DG-Ara-C NPs were measured. Additionally, the cytotoxicity of the NPs was determined via MTT assay. The results indicated that the average particle size of DG-Ara-C NPs was around 190 nm with a narrow size distribution (PDI = 0.1). TEM showed that DG-Ara-C NPs had a spherical morphology. Compared to free DG or Ara-C, the self-assembled DG-Ara-C NPs exhibited a better anti-tumor activity against solid tumor cells as well as leukemia cells. In conclusion, DG possesses dual role in the self-assembled NPs of DG-Ara-C conjugate, being as a promising anticancer drug and drug carrier.

Abstract
With Remdesivir being approved by FDA as a drug for the treatment of Corona Virus Disease 2019 (COVID-19), nucleoside drugs have once again received widespread attention in the medical community. Herein, we summarized modification of traditional nucleoside framework (sugar + base), traizole nucleosides, nucleoside analogues assembled by other drugs, macromolecule-modified nucleosides, and their bioactivity rules. 2′-“Ara”-substituted by –F or –CN group, and 3′-“ara” substituted by acetylenyl group can greatly influence their anti-tumor activities. Dideoxy dehydrogenation of 2′,3′-sites can enhance antiviral efficiencies. Acyclic nucleosides and L-type nucleosides mainly represented antiviral capabilities. 5-F Substituted uracil analogues exihibit anti-tumor effects, and the substrates substituted by –I, –CF3, bromovinyl group usually show antiviral activities. The sugar coupled with 1-N of triazolid usually displays anti-tumor efficiencies, while the sugar coupled with 2-N of triazolid mainly represents antiviral activities. The nucleoside analogues assembled by cholesterol, polyethylene glycol, fatty acid and phospholipid would improve their bioavailabilities and bioactivities, or reduce their toxicities.

Triple Strategies to Improve Oral Bioavailability by Fabricating Coamorphous Forms of Ursolic Acid with Piperine: Enhancing Water-Solubility, Permeability, and Inhibiting Cytochrome P450 Isozymes. Mol Pharm 2020; 17:4443-4462.

Abstract
As a BCS IV drug, ursolic acid (UA) has low oral bioavailability mainly because of its poor aqueous solubility/dissolution, poor permeability, and metabolism by cytochrome P450 (CYP) isozymes, such as CYP3A4. Most UA preparations demonstrated a much higher dissolution than that of its crystalline form yet a low drug concentration in plasma due to their lower consideration or evaluation for the permeability and metabolism issues. In the current study, a supramolecular coamorphous system of UA with piperine (PIP) was prepared and characterized by powder X-ray diffraction, differential scanning calorimetry, and scanning electron microscopy. In comparison to crystalline UA and UA in physical mixture, such coamorphous system enhanced solubility (5.3-7-fold in the physiological solution) and dissolution (7-8-fold in the physiological solution within 2 h) of UA and exhibited excellent physical stability under 90-day storage conditions. More importantly, the pharmacokinetic study of coamorphous UA in rats exhibited 5.8-fold and 2.47-fold improvement in AUC0-∞ value, respectively, compared with its free and mixed crystalline counterparts. In order to further explore the mechanism of such improvement, the molecular interactions of a coamorphous system in the solid state were investigated. Fourier transform infrared spectroscopy, solid-state 13C nuclear magnetic resonance spectroscopy, and density functional theory modeling suggested that intermolecular hydrogen bonds with strong interactions newly formed between UA and PIP after coamorphization. The in vitro permeability studies across Caco-2 cell monolayer and metabolism studies by rat hepatic microsomes indicated that free PIP significantly increased the permeability of UA and inhibited the enzymatic metabolism of UA by CYP3A4. However, PIP in the coamorphous combination exhibited a much lower level in the bioenhancing than its free form arising from the synchronized dissolution characteristic of the preparation (only 60% of PIP released in comparison to its free counterpart in 2 h). The in situ loop study in rats proposed that the acid-sensitive dissolution in the stomach of the coamorphous preparation helped to improve the effective free drug concentration, thereby facilitating PIP to play its role in bioenhancing. The current study offers an exploratory strategy to overcome poor solubility/dissolution, poor permeability, and metabolism by cytochrome P450 isozymes of the BCS IV drug to improve its oral bioavailability.

Abstract
Many drug molecules that are currently in the market suffer from short half-life, poor absorption, low specificity, rapid degradation, and resistance development. The design and development of lipophilic prodrugs can provide numerous benefits to overcome these challenges. Fatty acids (FAs), which are lipophilic biomolecules constituted of essential components of the living cells, carry out many necessary functions required for the development of efficient prodrugs. Chemical conjugation of FAs to drug molecules may change their pharmacodynamics/pharmacokinetics in vivo and even their toxicity profile. Well-designed FA-based prodrugs can also present other benefits, such as improved oral bioavailability, promoted tumor targeting efficiency, controlled drug release, and enhanced cellular penetration, leading to improved therapeutic efficacy. In this review, we discuss diverse drug molecules conjugated to various unsaturated FAs. Furthermore, various drug-FA conjugates loaded into various nanostructure delivery systems, including liposomes, solid lipid nanoparticles, emulsions, nano-assemblies, micelles, and polymeric nanoparticles, are reviewed. The present review aims to inspire readers to explore new avenues in prodrug design based on the various FAs with or without nanostructured delivery systems.

Abstract
Cytarabine (Ara-C) is an essential medicine used in the clinical treatment of acute lymphoblastic leukemia. However, Ara-C suffers from high hydrophilicity, rapid plasma degradation and significant side effects. Thus, herein, to eliminate the limitations of Ara-C in the treatment of leukemia, Sgc8 aptamer targeting and glutathione (GSH)-responsive polymeric micelles (PCL-ss-Ara@Sgc8-BSA) were prepared. The prodrug was synthesized via covalent bond formation between acryloyl chloride-terminal PCL-ss-PCL and Ara-C, and surface decoration with Sgc8-bovine serum albumin (Sgc8-BSA). The obtained PCL-ss-Ara@Sgc8-BSA exhibited good GSH-responsive drug release behavior, obvious targetability and sufficient antitumor effect to acute lymphoblastic leukemia (ALL) cells (CCRF-CEM). A hemolysis test was further carried out to demonstrate that these polymeric micelles are safe to be administrated intravenously. Compared with free Ara-C, PCL-ss-Ara@Sgc8-BSA significantly enhanced tumor growth inhibition in mice bearing CCRF-CEM xenograft tumors, while causing little side effects, and improved the survival rate of CCRF-CEM tumor-bearing mice in vivo. Therefore, this new self-assembling small molecular prodrug equipped with Sgc8 targeting function is a potential treatment for the targeted therapy of acute lymphoblastic leukemia.

Abstract
Cytarabine (Ara-C) has become cornerstones for the treatment of hatmatological malignancies for several decades; however, it still faces serious challenges in clinical applications due to its side effects such as hand foot syndrome (HFS) and stomatitis. Therefore, considerable researchers have devoted to looking for the new derivative with desirable activity and low toxicity. A new prodrug based on the conjugation of cytarabine with lauric acid (LA-Ara) was synthesized in our group, and it could self-assemble into nanofibers (NFs) in aqueous solution with high drug loading (57 wt%). The lauric acid moiety protects NH2 group of from the enzymatic attachment and simultaneously raises the lipophilicity of Ara-C, thus obviously prolongs its plasma half-life. The oil/water partition coefficient (lg P) and the permeability of cell membrane of LA-Ara were obviously increased compared with Ara-C. Furthermore, the in vitro gastrointestinal stability results indicated the prodrug was suitable to be administrated orally. In the current study, the in vitro cytotoxicity and in vivo anti breast cancer experimental results indicate LA-Ara markedly improved antitumor activity compared with free Ara-C. The favorable safety evaluations elucidated its potentiality for oral alternative treatment to Ara-C. Importantly, LA-Ara can effectively decrease the incidence of toxic effects (HFS and stomatitis) of Ara-C, thereby exhibiting favorable skin safety profile. Overall, these results indicated the LA-Ara would be an excellent candidate for further clinical investigation and simultaneously highlight the prospects of Ara-C prodrug strategies in solid tumors therapy.

Abstract
The short lifetime and easy quick elimination of the near-infrared (NIR) dye new indocyanine green (IR820) in the body restrict its practical application as a photothermal agent in cancer therapy. Meanwhile, the drawback of poor water solubility of the chemotherapeutic drug paclitaxel (PTX) largely restricts its clinical applications. Herein, we, for the first time, combined IR820 and PTX in an "all-in-one" fluorescence imaging-guided chemo-photothermal therapy (PTT) platform by a rational design of a novel pH- and enzyme-sensitive IR820-PTX conjugate assembly. Specifically, the IR820-PTX conjugate nanoparticles exhibit an extremely high therapeutic agent content (IR820 and PTX, 95.7%). Besides the good stability in bloodstream, the IR820-PTX nanoparticles can target tumors for high accumulation via the enhanced permeation and retention effect. Particularly, our IR820-PTX nanoparticles simultaneously solve the obstacles of PTX poor solubility and the short lifetime of IR820 for cancer therapy. The simultaneous release of the free drug and dye can efficiently kill tumor cells by the combination of PTT and chemotherapy via NIR irradiation. Furthermore, the combined therapy can be imaging-guided by measuring the NIR fluorescence imaging resulting from the IR820 component. Therefore, our rationally designed pH- and enzyme-sensitive IR820-PTX conjugate nanoparticles provide an alternative "all-in-one" option for an efficient combinational dual-therapy and imaging.

Abstract
With the advent from the laboratory bench to patient bedside in last five decades, vesicular systems have now come to be widely accepted as pragmatic means for controlled delivery of drugs. Their success stories include those of liposomes, niosomes and even the lately developed ethosomes and transferosomes. Pharmacosomes, which, as delivery systems offer numerous advantages and have been widely researched, however, remain largely unacknowledged as a successful delivery system. Though a large number of drugs have been derivatized and formulated into self-assembled vesicular systems, the term pharmacosomes has not been widely used while reporting them. Therefore, their relative obscurity may be attributed to the non-usage of the nomenclature of pharmacosomes by the researchers working in the area. We present a review on the scenario that lead to origin of these bio-inspired vesicles composed of self-assembling amphiphilic molecules. Various drugs that have been formulated into pharmacosomes, their characterization techniques, their properties relative to those of other vesicular delivery systems, and the success achieved so far are also discussed.

Rational Design of a New Self-Codelivery System from Redox-Sensitive Camptothecin-Cytarabine Conjugate Assembly for Effectively Synergistic Anticancer Therapy. Adv Healthc Mater 2017; 6.

Abstract
Herein, two careful selected anticancer drugs camptothecin (CPT) and cytarabine (Ara-C) with different biological action mechanisms and different water solubility are conjugated together through a glutathione (GSH) cleavable disulfide bond to construct a redox-sensitive drug-drug conjugate, which can self-assemble into nanoparticles, thus notably improving the water solubility of CPT and the cell membrane permeability of Ara-C. Compared with free drugs, the self-assembled CPT-ss-Ara nanoparticles can concentrate in tumor tissues through the enhanced permeability and retention (EPR) effect, then they can be rapidly internalized by tumor cells and degrade into free drugs for killing the tumor cells when exposed to the reductive environment (GSH) of tumor cells, thereby reducing the injury to normal cells. Meanwhile, the CPT-ss-Ara nanoparticles can effectively protect CPT and Ara-C molecules from biological inactivation before their arrival in tumor microenvironment since free CPT and Ara-C are easy to partly lose their therapy efficacy due to their structure degradation in blood circulation. The in vitro and in vivo anticancer experimental results indicate that simultaneous release of free CPT and Ara-C can realize synergistic chemotherapy effects, thus markedly improve their anticancer activity. Therefore, our designed carrier-free, redox-sensitive CPT-ss-Ara nanoparticles might have promising clinical application to combat cancers.
