Carbohydr Polym 2024; 338:122196. [PMID: 38763723 DOI: 10.1016/j.carbpol.2024.122196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/18/2024] [Accepted: 04/21/2024] [Indexed: 05/21/2024]
Abstract
Triple negative breast cancer (TNBC) represents the most aggressive and heterogenous disease, and combination therapy holds promising potential. Here, an enzyme-responsive polymeric prodrug with self-assembly properties was synthesized for targeted co-delivery of paclitaxel (PTX) and ursolic acid (UA). Hyaluronic acid (HA) was conjugated with UA, yielding an amphiphilic prodrug with 13.85 mol% UA and a CMC of 32.3 μg/mL. The HA-UA conjugate exhibited ∼14 % and 47 % hydrolysis at pH 7.4 and in tumor cell lysate. HA-UA/PTX NPs exhibited a spherical structure with 173 nm particle size, and 0.15 PDI. The nanoparticles showed high drug loading (11.58 %) and entrapment efficiency (76.87 %) of PTX. Release experiments revealed accelerated drug release (∼78 %) in the presence of hyaluronidase enzyme. Cellular uptake in MDA-MB-231 cells showed enhanced uptake of HA-UA/PTX NPs through CD44 receptor-mediated endocytosis. In vitro, HA-UA/PTX NPs exhibited higher cytotoxicity, apoptosis, and mitochondrial depolarization compared to PTX alone. In vivo, HA-UA/PTX NPs demonstrated improved pharmacokinetic properties, with 2.18, 2.40, and 2.35-fold higher AUC, t1/2, and MRT compared to free PTX. Notably, HA-UA/PTX NPs exhibited superior antitumor efficacy with a 90 % tumor inhibition rate in 4T1 tumor model and low systemic toxicity, showcasing their significant potential as carriers for TNBC combination therapy.

Int J Pharm 2024; 657:124163. [PMID: 38670473 DOI: 10.1016/j.ijpharm.2024.124163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/07/2024] [Accepted: 04/22/2024] [Indexed: 04/28/2024]
Abstract
Parenteral administration is one of the most commonly used drug delivery routes for nanoparticle-based dosage forms, such as lipid-based and polymeric nanoparticles. For the treatment of various diseases, parenteral administration include intravenous, subcutaneous, and intramuscular route. In drug development phase, multiparameter strategy with a focus on drug physicochemical properties and the specificity of the administration route is required. Nanoparticle properties in terms of size and targeted delivery, among others, are able to surpass many drawbacks of conventional dosage forms, but these unique properties can be a bottleneck for approval by regulatory authorities. Quality by Design (QbD) approach has been widely utilized in development of parenteral nanoparticle-based dosage forms. It fosters knowledge of product and process quality by involving sound scientific data and risk assessment strategies. A full and comprehensive investigation into the state of implementation and applications of the QbD approach in these complex drug products can highlight the gaps and challenges. In this review, the analysis of critical attributes and Design of Experiment (DoE) approach in different nanoparticulate systems, together with the proper utilization of Process Analytical Technology (PAT) applications are described. The essential of QbD approach for the design and development of nanoparticle-based dosage forms for delivery via parenteral routes is discussed thoroughly.

Int J Biol Macromol 2024; 267:131491.

Abstract
Quetiapine hemifumarate (QF) delivery to the CNS via conventional formulations is challenging due to poor solubility and lower oral bioavailability (9 %). Similarly, many other second-generation antipsychotics, such as olanzapine, clozapine, and paliperidone, have also shown low oral bioavailability of <50 %. Hence, the present work was intended to formulate QF-loaded biodegradable PLGA-NPs with appropriate surface charge modification through poloxamer-chitosan and investigate its targeting potential on RPMI-2650 cell lines to overcome the limitations of conventional therapies. QF-loaded poloxamer-chitosan-PLGA in-situ gel (QF-PLGA-ISG) was designed using emulsification and solvent evaporation techniques. Developed QF-PLGA-ISG were subjected to evaluation for particle size, PDI, zeta potential, ex-vivo mucoadhesion, entrapment efficiency (%EE), and drug loading, which revealed 162.2 nm, 0.124, +20.5 mV, 52.4 g, 77.5 %, and 9.7 %, respectively. Additionally, QF-PLGA formulation showed >90 % release within 12 h compared to 80 % of QF-suspension, demonstrating that the surfactant with chitosan-poloxamer polymers could sustainably release medicine across the membrane. Ex-vivo hemolysis study proved that developed PLGA nanoparticles did not cause any hemolysis compared to negative control. Further, in-vitro cellular uptake and transepithelial permeation were assessed using the RPMI-2650 nasal epithelial cell line. QF-PLGA-ISG not only improved intracellular uptake but also demonstrated a 1.5-2-fold increase in QF transport across RPMI-2650 epithelial monolayer. Further studies in the EpiNasal™ 3D nasal tissue model confirmed the safety and efficacy of the developed QF-PLGA-ISG formulation with up to a 4-fold increase in transport compared to plain QF after 4 h. Additionally, histological reports demonstrated the safety of optimized formulation. Finally, favorable outcomes of IN QF-PLGA-ISG formulation could provide a novel platform for safe and effective delivery of QF in schizophrenic patients.

Abstract
Second-generation antipsychotics, quetiapine hemifumarate (QF), exhibited highly active against negative and positive signs of psychosis. However, contemporary reports have shown that long-term therapy with QF causes lethal thrombocytopenia and leukopenia. Hence, to circumvent the drawbacks of available therapies, the current work aimed to design a QF-loaded biodegradable nanoemulsion (QF-NE) with suitable surface charge modification by poloxamer-chitosan and evaluate its targeting efficiency against RPMI-2650 cell lines. QF-loaded poloxamer-chitosan in-situ gel (QF-Nanoemulgel) was formulated through the O/W emulsification aqueous titration technique and optimized using the QbD approach. Optimized QF-Nanoemulgel subjected to evaluate for globule size, PDI, zeta potential, %T, viscosity, %EE, and ex-vivo mucoadhesive strength were found to be 15.0 ± 0.3 nm, 0.05 ± 0.001, -18.3 ± 0.2 mV, 99.8 ± 0.8 %, 13.5 ± 2.1 cP, 69.0 ± 1.5 %, and 43.7 ± 1.5 g, respectively. QF-Nanoemulgel revealed sustained release and obeyed zero-order kinetics compared to QF-NE and QF-suspension. Additionally, nanoformulations treated blood samples did not cause hemolytic activity compared to drug and negative control after 10 h treatment. Further, in-vitro cytotoxicity, cellular uptake, and permeation of 12.5 and 25 μM QF-Nanoemulgel were assessed on RPMI-2650 cells and discovered nontoxic with 0.55 ± 0.02 µg and 1.1 ± 0.04 µg cellular permeation, respectively, which ensured the safety and potency of QF-Nanogel. Current research revealed the successful development of intranasal QF-Nanoemulgel as a novel dosage form for the safe and effective delivery of QF in schizophrenia patients.

Abstract
The present study attempts to treat S. aureus-induced soft skin infections using a combinatorial therapy with an antibiotic, Ciprofloxacin (CIP), and an efflux pump inhibitor 5-Nitro-2-(3-phenylpropoxy) pyridine (5-NPPP) through a smart hydrogel delivery system. The study aims to reduce the increasing rates of infections and antimicrobial resistance; therefore, an efflux pump inhibitor molecule is synthesized and delivered along with an antibiotic to re-sensitize the pathogen towards antibiotics and treat the infections. CIP-loaded polyvinyl alcohol (PVA) hydrogels at varying concentrations were fabricated and optimized by a chemical cross-linking process, which exhibited sustained drug release for 5 days. The compound 5-NPPP loaded hydrogels provided linear drug release for 2 days, necessitating the need for the development of polymeric nanoparticles to alter the release drug pattern. 5-NPPP loaded Eudragit RSPO nanoparticles were prepared by modified nanoprecipitation-solvent evaporation method, which showed optimum average particle size of 230-280 nm with > 90% drug entrapment efficiency. The 5-NPPP polymeric nanoparticles loaded PVA hydrogels were fabricated to provide a predetermined sustained release of the compound to provide a synergistic effect. The selected 7% PVA hydrogels loaded with the dual drugs were evaluated using Balb/c mice models induced with S. aureus soft skin infections. The results of in vivo studies were evidence that the dual drugs loaded hydrogels were non-toxic and reduced the bacterial load causing re-sensitization towards antibiotics, which could initiate re-epithelization. The research concluded that the PVA hydrogels loaded with CIP and 5-NPPP nanoparticles could be an ideal and promising drug delivery system for treating S. aureus-induced skin infections.

Abstract
Although paclitaxel is a front-line chemotherapeutic agent for the treatment of metastatic breast cancer, its intravenous therapy produces deleterious adverse effects. In an attempt to address the issue, the present study aimed to develop a paclitaxel loaded thermosensitive/thermoresponsive hydrogel (PTXNp-TGel) for loco-regional administration to breast tumors to provide dose-dense chemotherapy. Poloxamer and xanthan gum were used to prepare TGel by the cold method. In vitro and in vivo performance of PTXNp-TGel was compared with TGel, pure drug loaded TGel (PTX-TGel) and marketed formulation, Taxol®. The formulated PTXNp-TGel showed acceptable gelation temperature and time (37 °C and 57 s), lower viscosity at room temperature and higher viscosity at body temperature to support sol-gel transition with increasing temperature, and sustained drug release up to 21 days. Additionally, PTXNp-TGel showed negligible hemolytic toxicity as compared to PTX-TGel and Taxol®. Intratumoral administration of PTXNp-TGel produced significantly higher antitumor activity as indicated by lowest relative tumor volume (1.50) and relative antitumor proliferation rate (27.71 %) in comparison with PTX-TGel, Taxol®, and PTXNp (p < 0.05). Finally, insignificant body weight loss during the experimental period, lack of hematotoxicity, nephrotoxicity, and hepatotoxicity imply improved therapeutic performance of the locally administrated dose-dense therapy of PTXNp-TGel as compared to Taxol®.

Abstract
Increasing interest in developing antifibrotic therapies became a paramount priority due to the globally raised incidence of deaths secondary to hepatic cirrhosis. This work deals with the development of innovative antifibrotic pirfenidone -loaded lecithin core nanocapsules. This with the intention to target the liver and to increase the drug bioavailability, reducing drug liver toxicity, and studying the associated hepatic microenvironment changes. PFD-loaded lecithin nanocapsules (PFD-LENCs) were prepared using the natural lipoid S45 for its dual benefits of being both a lipid and an amphiphilic surfactant. The selected formulation exhibited in vitro sustained drug release up to 24 h compared to free PFD, which is consistent with the studied pharmacokinetic profile. The studied cytotoxicity of PFD as well as PFD-LENCs exhibited negligible cytotoxicity in normal oral epithelial cells. For exploring the capability of the PFD-LENCs in reaching the liver; in vivo tracing using CLSM, in vivo biodistribution to the vital organs were conducted and electron microscopic examination for depicting nanoparticles in liver tissue was performed. Results revealed the capability of the prepared fluorescent LENC2 in reaching the liver, PFD-LENCs detection in the Disse space of the liver and the significant accumulation of PFD-LENCs in liver tissue compared to the other tested organs. The assessment of the necro-inflammatory, antioxidant and the anti-fibrotic effect of PFD-LENCs (50 & 100 mg/kg) exhibited a significant decrease of liver enzymes, TNF-α, TGF-β, Col-1, α-SMA, and TIMP-1, and a significant increase of catalase enzyme and MMP2 compared to free PFD. EM studies, revealed often detection of dendritic cells in PFD-LENCs (100 mg/kg) treated mice and abnormal collagen structure which can represent an adjunct contribution to the antifibrotic mechanism of PFD-LENCs. In conclusion, the development of this innovative PFD loaded lecithin nanocapsules achieved a targeting ability to the liver, controlled drug release, thereby increase the PFD therapeutic value in downregulating hepatic fibrosis in adjunct with the reduction of liver toxicity.

Abstract
PURPOSE To counteract early morning pathology like hypertension a time-dependent release of the drug is required. This study is focused to formulate a pulsatile and mucoadhesive drug delivery system of an ACE inhibitor Perindopril Erbumine. METHOD Two matrix tablets were punched with Eudragit RSPO, Eudragit RLPO, and HPMC K15M using a 3-3-3 Box-Behnken Design of Response Surface Methodology. Based on the design-optimized formulation P1T3 and P2T8 were coated for a lag time with compression coating of HPMC K4M and a blend of 1:1 ratio of ethylcellulose and carbopol polymer and further encapsulated in a Eudracap™ capsule to provide gastric resistance. RESULT The in-vitro release data confirmed an initial pause phase of 4.5 h then release of the drug for 5.2 ± 0.3 h to cope with the early morning rush in blood pressure. After that, a gap of 6 h and then sustained release of the drug for 10.5 ± 0.5 h. From the ex-vivo study, mucoadhesive strength was obtained as 55.13 ± 0.03 gm and 56.39 ± 0.02 gm for P1T3 and P2T8 respectively. The lag time for coated tablet P1T3 came to 2.15 ± 0.15 h and for P2T8 11.9 ± 0.10 h proving the coating efficiency of polymers. CONCLUSION The current study strongly suggests that perindopril Erbumine in association with Eudragit and Hypromellose polymer can open a path for the time-regulated release of the drug for hypertension chronotherapy with less risk of dose dumping.

Abstract
Recent findings revealed that low-concentration paclitaxel(DTX) could enhance cytotoxicity by upregulating p53 expression in lung cancer cell lines. So, co-delivery of DTX and RFP-p53 gene with PEA nanoparticles (NPs) was studied. The prepared DTX loaded PEA NPs (PEA/DTX) were characterized by particle size distribution, morphology, zeta potential, and crystallography and cytotoxicity. Results showed that the PEA/DTX NPs had a mall particle size (≤100 nm), moderate zeta potential (≥40 mV) and drug loading of 9.0%, DTX was released from PEA/DTX NPs in an extended period in vitro. More important, agarose gel electrophoresis showed that PEA/DTX cationic NPs were able to completely bind RFP-p53 gene with mean particles size and zeta potential. Studies on cellular uptake of (PEA/DTX)/RFP-p53 NPs demonstrated that both drug and gene were effectively taken up by A549 tumor cells. It was found that intravenous injection of (PEA/DTX)/RFP-p53 NPs efficiently inhibited growth of subcutaneous A549 carcinoma in vivo (p < 0.05) and was significantly less side effect than that of mice treated with the other groups. Therefore, the (PEA/DTX)/RFP-p53 NPs might be a promising candidate for A549 cancer therapy.

Abstract
Background: Serious side effects caused by paclitaxel formulation, containing toxic solubilizer Cremophor® EL, and its nonspecific accumulation greatly limit clinical paclitaxel application. Aim: To design paclitaxel-loaded copolymer of lactic and glycolic acids nanoparticles decorated with alpha-fetoprotein third domain (rAFP3d-NP) to increase paclitaxel safety profile. Methods: rAFP3d-NP was obtained via carbodiimide technique. Results: The particles were characterized with high paclitaxel loading content of 5% and size of 280 nm. rAFP3d-NP revealed biphasic profile with 67% release of paclitaxel during 220 h. Increased area under the curveinf and mean residence time values after rAFP3d-NP administration confirmed prolonged blood circulation compared with paclitaxel. rAFP3d-NP demonstrated significant tumor growth inhibition at 4T1 and SKOV-3 models. Conclusion: rAFP3d-NP is a promising delivery system for paclitaxel and can be applied similarly for delivery of other hydrophobic drugs.

SBA-15 Mesoporous Silica as Delivery Vehicle for rhBMP-2 Bone Morphogenic Protein for Dental Applications. NANOMATERIALS 2022; 12:nano12050822. [PMID: 35269309 PMCID: PMC8912683 DOI: 10.3390/nano12050822] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 02/20/2022] [Accepted: 02/22/2022] [Indexed: 01/14/2023]
Abstract
(1) Background: A proposed approach to promote periodontal tissue regeneration in cases of peri-implantitis is the local administration of growth factors at the implant site. Recombinant human bone morphogenetic protein-2 (rh-BMP-2) can effectively promote bone regeneration and osseointegration and the development of appropriate carriers for its delivery is of paramount importance. The aim of the present study was to develop SBA-15 mesoporous nanoparticles (MSNs) with varying porosity, evaluate their biocompatibility with human Periodontal Ligament Cells (hPDLCs) and to investigate their effectiveness as carriers of rh-BMP-2. (2) Methods: SBA-15 type mesoporous silicas were synthesized via sol-gel reaction. The calcined SBA-15 samples were characterized by N2 porosimetry, Fourier transform-infrared spectrometry (FTIR), Scanning (SEM) and Transmission Electron Microscopy (TEM). Rh-BMP-2 loading and release kinetics were evaluated by UV spectroscopy. (3) Results: MSNs presented hexagonally arranged, tubular pores of varying length and diameter. Slightly higher loading capacity was achieved for SBA-15 with large pores that presented good hemocompatibility. MTT assay revealed no cytotoxic effects for all the tested materials, while SBA-15 with large pores induced a significant upregulation of cell viability at day 5. (4) Conclusions: SBA-15 MSNs may prove a valuable delivery platform towards the effective release of bone-inducing proteins.
