good selectivity and potency against four prostate cancer cell lines (DU 145, PC-3, LNCaP, and PPC-1). The structure–activity relationship (SAR) of the side chain, the thiazolidine ring, and phenyl substituents is discussed. Cell cycle analysis showed that the percentage of cancer cells undergoing apoptosis (sub-G1 phase) increased after treatment with 1b and 3ad, which also strongly inhibited melanoma
合成了一系列(2RS , 4R ) -2-芳基噻唑烷-4-甲酰胺(ATCAA)。与对照细胞(分别为成纤维细胞和 RH7777)相比,评估了针对黑色素瘤和前列腺癌细胞的抗增殖活性。化合物3id对三种黑色素瘤细胞系(B16-F1、A375 和 WM-164)表现出最佳的选择性和生长抑制活性。化合物15b和3ac对四种前列腺癌细胞系(DU 145、PC-3、LNCaP 和 PPC-1)具有良好的选择性和效力。讨论了侧链、噻唑烷环和苯基取代基的构效关系(SAR)。细胞周期分析表明,用1b和3ad处理后,发生凋亡(亚 G1 期)的癌细胞百分比增加,这也强烈抑制了黑色素瘤集落的形成。对带有 A375 黑色素瘤肿瘤的裸鼠的体内研究表明,化合物1b以剂量依赖性方式抑制肿瘤生长。在 10 mg/kg 的剂量下,1b显着抑制黑色素瘤肿瘤的生长,并且比 60 mg/kg 的达卡巴嗪显示出更高的疗效。
