Abstract

OBJECTIVE

Addressing both the initial treatment response and subsequent paclitaxel resistance is a pivotal concern. Nano drug delivery, an emerging approach, presents a cutting-edge alternative to conventional chemotherapy.

METHODS

This investigation synthesized PEGylated nanoparticles (NPs) via the Reverse Phase Evaporation technique for liposomal NPs. Characteristics such as zeta potential, size, drug release and polydispersity index (PDI) were subjected to evaluation. Subsequently, cytotoxicity assays were conducted on gastric cancer cells (AGS) following 24 and 48-hour incubation periods.

RESULTS

In this study, the liposomal NPs had a zeta potential of -22 mV and a particle size of 285 nm. The Entrapment efficiency was determined as 41% that occurred physically. Additionally, the liposomal NPs demonstrated a high drug retention rate (39% remained after 72 hours), and they exhibited significantly increased cytotoxicity compared to the free drug, confirming their effectiveness as a suitable carrier for paclitaxel during both incubation periods (P<0.05).

CONCLUSION

These findings collectively advocate the potential of liposomal NPs as promising contenders for effective nano-drug application in propelling chemotherapy forward.

摘要

目的

解决初始治疗反应和随后的紫杉醇耐药性是一个关键问题。纳米药物递送是一种新兴的方法,为传统化疗提供了一种前沿的替代方案。

方法

本研究通过反相蒸发技术合成了用于脂质体 NPs 的聚乙二醇化纳米颗粒 (NPs)。对 zeta 电位、粒径、药物释放和多分散指数 (PDI) 等特性进行了评估。随后,对胃癌细胞 (AGS) 进行了 24 和 48 小时孵育后的细胞毒性测定。

结果

在这项研究中,脂质体 NPs 的 zeta 电位为-22 mV,粒径为 285 nm。包封效率为 41%,这是通过物理方式实现的。此外,脂质体 NPs 表现出高药物保留率(72 小时后仍有 39%),与游离药物相比,它们表现出显著增强的细胞毒性,证实了它们在两个孵育期作为紫杉醇合适载体的有效性(P<0.05)。

结论

这些发现共同证明了脂质体 NPs 作为有效纳米药物应用的有前途的候选物,为推动化疗向前发展提供了潜力。
