Eight sansalvamide A peptide analogues with 4â²-fluoride, 4â²-chloride, 4â²-bromide, 4â²-iodide, and 4â²-methoxyphenylalanine moieties were synthesized. The effect of these para-substitutions of sansalvamide A peptide on their cytotoxicity was evaluated using HCT-116, MDA-MB-231, HT-29, HCT-15, K562, HeLa, and A549 cell lines. The 4â²-methoxyphenylalanine analog of sansalvamide A peptide was found to be a promising antitumor agent.
合成了8种具有4'²-氟、4'²-氯、4'²-溴、4'²-碘和4'²-甲氧基苯丙氨酸分子的山沙酰胺A肽类似物。研究人员使用 HCT-116、MDA-MB-231、HT-29、HCT-15、K562、HeLa 和 A549 细胞系评估了山沙酰胺 A 肽的这些对位取代对其细胞毒性的影响。结果发现,4²-甲氧基苯丙氨酸类似物丹沙酰胺 A肽是一种很有前景的抗肿瘤药物。
