The therapeutic potential of epigallocatechin-3-gallate (EGCG), a green tea polyphenol with anticancer properties, is limited by its inability to specifically reach tumors following intravenous administration. The purpose of this study was to determine whether a tumor-targeted vesicular formulation of EGCG would suppress the growth of A431 epidermoid carcinoma and B16-F10 melanoma in vitro and in vivo.
MATERIALS & METHODS: Transferrin-bearing vesicles encapsulating EGCG were administered intravenously to mice bearing subcutaneous A431 and B16-F10 tumors.
The intravenous administration of EGCG encapsulated in transferrin-bearing vesicles resulted in tumor suppression in 40% of A431 and B16-F10 tumors. Animal survival was improved by more than 20 days compared with controls.
Encapsulation of EGCG in transferrin-bearing vesicles is a promising therapeutic strategy.
表没食子儿茶素没食子酸酯(EGCG)是一种具有抗癌特性的绿茶多酚,其治疗潜力受到限制,因为它在静脉给药后无法专门到达肿瘤。本研究旨在确定 EGCG 的肿瘤靶向囊泡制剂是否会抑制体外和体内 A431 表皮样癌细胞和 B16-F10 黑色素瘤的生长。
将携带转铁蛋白的囊泡包裹的 EGCG 静脉给药给患有皮下 A431 和 B16-F10 肿瘤的小鼠。
静脉给予转铁蛋白囊泡包裹的 EGCG 导致 40%的 A431 和 B16-F10 肿瘤受到抑制。与对照组相比,动物的存活时间延长了 20 多天。
将 EGCG 包裹在转铁蛋白囊泡中是一种很有前途的治疗策略。
