In order to obtain diverse S-acylation inhibitors and address the defects of existing S-acylation inhibitors, a series of novel covalent S-acylation inhibitors are designed through synthesis. According to the results of MTT assay, most compounds produce a better anti-proliferation effect on MCF-7, MGC-803 and U937 cell lines than 2-BP. Among them, 8d, 8i, 8j and 10e exert a significant inhibitory effect
为了获得多样化的S-酰化抑制剂并解决现有S-酰化抑制剂的缺陷,通过合成设计了一系列新型共价S-酰化抑制剂。 MTT法结果显示,大多数化合物对MCF-7、MGC-803和U937细胞系产生比2-BP更好的抗增殖作用。其中8d 、 8i 、 8j和10e对MCF-7细胞有显着的抑制作用,IC 50值均降至20 μM以下。此外,某些化合物对3T3细胞系的毒性作用不如2-BP显着。根据酰基生物素交换(ABE)实验结果,大多数都具有抑制S-酰化作用,其中8i在这方面表现最好,在20 μM浓度下抑制率达到89.3%。分子对接结果显示8i与周围氨基酸的缀合。此外, 8i不仅能抑制MCF-7细胞系的迁移,还能使其停滞在G0/G1期,从而促进细胞凋亡。 图文摘要
