摘要: 采用热诱导法制备表没食子儿茶素没食子酸酯-抗坏血酸-β-乳球蛋白纳米粒(EGCG-Vc-β-Lg),考察EGCG与Vc摩尔比对纳米粒粒径、Zeta电位、包埋率、装载量、颜色变化的影响;运用噻唑蓝(MTT)比色法和胞质分裂阻滞微核试验(CBMNT)研究纳米粒对人体黑色素瘤细胞(A-375)、食管癌细胞(TE-1)的增殖抑制作用和初步作用机制。结果表明:EGCG-Vc-β-Lg对A-375、TE-1的增殖抑制有增效作用,并且显著提高了其微核率、凋亡率和坏死率。

Abstract: (-)-Epigallocatechin-3-gallate (EGCG) and ascorbic acid (Vc) were loaded in heat treated β-lactoglobulin (β-Lg) to prepare EGCG naonparticles. The effects of EGCG and Vc with different molar ratios on the particle size, Zeta potential, entrapment efficiency, loading capacity, the change of color were investigated. The antitumor activity and mechanism of EGCG naonparticles were obtained by MTT assay and cytokinesis block micronucleus test (CBMNT). The results showed that EGCG naonparticles had stronger inhibition on human melanoma cell (A-375) and esophageal carcinoma cell (TE-1), and significantly increased the number of micronuclei, necrosis and apoptosis of the A-375 and TE1-1 carcinoma cell.

Key words: (-)-epigallocatechin-3-gallate (EGCG), Vc, β-lactoglobulin (β-Lg);, nanoparticle, antitumor activity
