Abstract

Basis on molecular docking and pharmacophore analysis of naphthoquinone moiety, a total of 23 compounds were designed and synthesised. With the help of reverse targets searching, anti-cancer activity was preliminarily evaluated, most of them are effective against some tumour cells, especially compound 12: 1-(5,8-dihydroxy-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-4-methylpent-3-en-1-yl-4-oxo-4-((4-phenoxyphenyl)amino) butanoate whose IC₅₀ against SGC-7901 was 4.1 ± 2.6 μM. Meanwhile the anticancer mechanism of compound 12 had been investigated by AnnexinV/PI staining, immunofluorescence, Western blot assay and molecular docking. The results indicated that this compound might induce cell apoptosis and cell autophagy through regulating the PI3K signal pathway.

摘要

基于萘醌部分的分子对接和药效团分析，总共设计和合成了23种化合物。借助反向靶标搜索，初步评估了其抗癌活性，其中大多数对某些肿瘤细胞有效，尤其是化合物12：1-（5,8-dihydroxy-1,4-dioxo-1,4-dihydronaphthalen -2-基）-4-甲基戊-3-烯-1-基-4-氧代-4-（（4-苯氧基苯基）氨基）丁酸酯，其对SGC-7901的IC ₅₀为4.1±2.6μM。同时通过AnnexinV / PI染色，免疫荧光，Western印迹分析和分子对接研究了化合物12的抗癌机理。结果表明该化合物可能通过调节PI3K信号通路诱导细胞凋亡和细胞自噬。
