Aim: The study explores glycerosomes as effective vesicular systems for transdermal delivery of atorvastatin (ATO) to overcome drawbacks related to its oral administration.Methodology: The objectives of this study were to formulate, by thin-film hydration method, optimize using definitive screening design and evaluate ATO-loaded glycerosomes (ATOG) which were then incorporated into patch followed by the evaluation of glycerosomes containing different concentration of glycerol.Results & discussion: Vesicle size, Polydispersity index (PDI), zeta potential, entrapment efficiency and loading capacity of spherical ATOG (0-30%w/w) showed 137.3-192d.nm, 0.292-0.403, -3.81 to-6.76mV, 80.03-92.77% and 5.80-6.40%, respectively. In-vitro release study showed sustained release, increased skin permeability and better cell viability than pure drug. ATOG patches showed greater skin permeability than pure drug and ATO-liposomal patches.Conclusion: The study concludes that ATOGs are promising for effective transdermal delivery.

目的:本研究探讨了甘油囊作为阿托伐他汀(ATO)透皮给药的有效囊泡系统,以克服口服给药的相关缺点:本研究的目的是通过薄膜水合法配制、使用确定性筛选设计进行优化并评估负载 ATO 的甘油囊(ATOG),然后将其纳入贴片,接着评估含有不同浓度甘油的甘油囊:球形 ATOG(0-30%w/w)的囊泡大小、多分散指数(PDI)、ZETA电位、夹持效率和负载能力分别为 137.3-192d.nm、0.292-0.403、-3.81-6.76mV、80.03-92.77% 和 5.80-6.40%。体外释放研究显示,与纯药物相比,ATOG 贴片具有持续释放、皮肤渗透性更强和细胞存活率更高的特点。ATOG 贴片的皮肤渗透性高于纯药物和 ATO 脂质体贴片:该研究得出结论,ATOGs 有望实现有效的透皮给药。

Aim: Dasatinib (DST) is an oral tyrosine kinase inhibitor with poor aqueous solubility. To outwit this issue, a solid self-nano emulsifying drug delivery system (S-SNEDDS) of DST was formulated.Methods: I-optimal mixture design was used for optimization of DST-loaded SNEDDS using Linalool, Cremophor RH40 and Transcutol P. S-SNEDDS underwent physicochemical characterization, in-vitro release and ex-vivo permeation, cell-based assays and pharmacokinetic study.Results: DST-S-SNEDDS showed globule size and PDI of 141.53 ± 5.371 nm and 0.282 ± 0.020, respectively. DST-S-SNEDDS revealed significantly lower IC50 (1.825 μg/mL) than free DST (7.298 μg/mL) in MDA-MB-231. In-vivo pharmacokinetic study revealed 1.94-fold increment in AUC0-t for the DST-S-SNEDDS group than free DST.Conclusion: S-SNEDDS could be promising approach for improving bioavailability and efficacy of DST.

目的:达沙替尼(DST)是一种口服酪氨酸激酶抑制剂,水溶性较差。为了解决这一问题,我们配制了一种 DST 固体自纳米乳化给药系统(S-SNEDDS):方法:使用芳樟醇、Cremophor RH40 和 Transcutol P 对负载 DST 的 SNEDDS 进行了 I-optimal 混合物设计,并对 S-SNEDDS 进行了理化表征、体外释放和体内渗透、细胞检测和药代动力学研究:结果:DST-S-SNEDDS 的球形尺寸和 PDI 分别为 141.53 ± 5.371 nm 和 0.282 ± 0.020。在 MDA-MB-231 中,DST-S-SNEDDS 的 IC50(1.825 μg/mL)明显低于游离 DST(7.298 μg/mL)。体内药代动力学研究显示,DST-S-SNEDDS 组的 AUC0-t 比游离 DST 组增加了 1.94 倍:结论:S-SNEDDS 是提高 DST 生物利用度和疗效的有效方法。

Aim: This study aimed to formulate erlotinib hydrochloride (ERT-HCL)-loaded chitosan (CS) and poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) using Quality-by-Design (QbD) to optimize critical quality attributes (CQAs). Materials & methods: Quality target product profile (QTPP) and CQAs were initially established. Based on L8-Taguchi screening and risk assessments, central composite design (CCD) design was used to optimize NPs. Results: ERT-HCL-loaded CS-PLGA NPs had a mean particle diameter, zeta potential and entrapment efficiency of 226.50 ± 1.62 d.nm, 27.66 ± 0.64 mV and 78.93 ± 1.94 %w/w, respectively. The NPs exhibited homogenous spherical morphology and sustained release for 72 h. Conclusion: Using systematic QbD approach, ERT-HCL was encapsulated in CS-PLGA NPs, optimizing CQAs. These findings propel future research for improved NSCLC treatment.

Synthesis and release studies on amylose-based ester prodrugs of fenamic acid NSAIDs. 基于淀粉糖的非那根酸类非甾体抗炎药酯原药的合成和释放研究。
IF 3 Q2 PHARMACOLOGY & PHARMACY Pub Date : 2024-01-01 Epub Date: 2024-09-17 DOI: 10.1080/20415990.2024.2400041

Aim: To achieve colon-targeted release of mefenamic acid from its ester-linked amylose prodrugs.Materials & methods: The prodrug was characterized by 1H NMR and IR spectroscopy. Drug activation and release profile was studied in enzyme enriched simulated physiological media via UV-vis spectroscopy and was validated with HPLC analysis. ELISA assay was employed for evaluating the % inhibition of COX-1 and COX-2 inhibition at different concentrations of the prodrug preincubated with ester and/ or amylose hydrolyzing enzymes. SEM studies further validated the performance of the prodrug under simulated physiological conditions.Results: Pancreatin was essential for the prodrug activation in SIM to make the ester bonds in prodrug vulnerable to hydrolysis by esterase. This evidence was confirmed by drug release studies, HPLC analysis, ELISA assay and SEM investigation where the ester conjugated prodrug showed marked stability in physiological media only to get activated in the presence of amylose degrading enzyme.Conclusion: Ester linked amylose-mefenamic acid conjugate showed both enzyme responsive activation and release in SIM.

材料与方法:通过酯联淀粉原药实现甲灭酸的结肠靶向释放:通过 1H NMR 和 IR 光谱对原药进行表征。在富含酶的模拟生理介质中,通过紫外可见光谱对药物的活化和释放曲线进行了研究,并通过高效液相色谱分析进行了验证。酶联免疫吸附试验(ELISA)用于评估不同浓度的原药与酯和/或淀粉水解酶预孵育时对 COX-1 和 COX-2 的抑制率。扫描电镜研究进一步验证了原药在模拟生理条件下的性能:结果:胰蛋白酶是 SIM 中原药活化的关键,它使原药中的酯键容易被酯酶水解。这一证据通过药物释放研究、高效液相色谱分析、酶联免疫吸附试验和扫描电镜研究得到了证实,在这些研究中,酯结合原药在生理介质中表现出明显的稳定性,只有在淀粉降解酶存在时才会被激活:结论:酯类连接的淀粉-甲灭酸共轭物在 SIM 中表现出酶反应性激活和释放。

Aim: Benznidazole (BNZ), a class-II drug, is the primary treatment for Chagas disease, but its low aqueous solubility presents challenges in formulation and efficacy. Nanosuspensions (NS) could potentially address these issues.Methods: BNZ-NS were prepared using a simple, organic solvents-free nano-milling approach. Physicochemical characterizations were conducted on both NS and lyophilized solid-state BNZ-nanocrystals (NC).Results: BNZ-NS exhibited particle size <500 nm, an acceptable polydispersity index (0.23), high Z-potential, and physical stability for at least 90 days. BNZ-NC showed tenfold higher solubility than pure BNZ. Dissolution assays revealed rapid BNZ-NS dissolution. BNZ-NC demonstrated biocompatibility on an eukaryotic cell and enhanced BNZ efficacy against trypomastigotes of Trypanosoma cruzi.Conclusion: BNZ-NS offers a promising alternative, overcoming limitations associated with BNZ for optimized pharmacotherapy.

目的:苯并咪唑(BNZ)是一种二类药物,是治疗南美锥虫病的主要药物,但其水溶性较低,给配制和疗效带来了挑战。纳米悬浮剂(NS)有可能解决这些问题。方法:采用简单、无有机溶剂的纳米研磨方法制备 BNZ-NS。对纳米悬浮剂和冻干固态 BNZ 纳米晶体(NC)进行了物理化学表征。结果显示BNZ-NS 的粒度与克鲁斯锥虫的粒度一致。结论:BNZ-NSBNZ-NS 是一种很有前景的替代品,它克服了 BNZ 在优化药物治疗方面的局限性。

Aim: Design of moxifloxacin and ornidazole co-loaded polycaprolactone and gelatin nanofiber dressing for diabetic wounds. Materials & methods: The composite nanofibers were prepared using electrospinning technique and characterized for in vitro drug release, antibacterial activity, laser doppler and in vivo wound healing. Results: The optimized nanofiber demonstrated an interconnected bead free nanofiber with average diameter <200 nm. The in vitro drug release & antimicrobial studies revealed that optimized nanofiber provided drug release for >120 h, thereby inhibiting growth of Escherichia coli and Stapyhlococcus aureus. An in vivo wound closure study on diabetic rats found that optimized nanofiber group had a significantly higher wound closure rate than marketed formulation. Conclusion: The nanofiber provided prolonged drug release and accelerated wound healing, making it a promising candidate for diabetic wound care.

目的:设计用于糖尿病伤口的莫西沙星和奥硝唑共负载聚己内酯和明胶纳米纤维敷料。材料与方法:采用电纺丝技术制备复合纳米纤维,并对体外药物释放、抗菌活性、激光多普勒和体内伤口愈合进行表征。结果:体外药物释放和抗菌研究表明,优化纳米纤维的药物释放时间超过 120 小时,从而抑制了大肠杆菌和金黄色葡萄球菌的生长。对糖尿病大鼠进行的体内伤口闭合研究发现,优化纳米纤维组的伤口闭合率明显高于市售制剂。结论纳米纤维可延长药物释放时间并加速伤口愈合,因此有望用于糖尿病伤口护理。
