salt 1, all the dithiocarbamate ester analogs (2 and 4a–4g) displayed lower cytotoxicity than compound 1 (PC3, IC50 = 0.087 ± 0.005 μM; DU145, IC50 = 0.079 ± 0.003 μM and LNCaP, IC50 = 0.079 ± 0.003 μM) on day 7 of treatment. Consequently, it appears that S-alkylation of compound 1 leads to a more stable dithiocarbamate ester derivative that resulted in lower anticancer activity in the prostate cancer
通过使依替丁的N2'-位衍生化,合成了一个少量的依替丁二硫代氨基甲酸酯衍生物库,产率为25-86%。这些化合物在雄激素受体阳性LNCaP和雄激素受体阴性PC3和DU145前列腺癌细胞系中的抗癌评估显示出时间依赖性和剂量依赖性细胞毒性。除化合物4c外,本研究中的所有二硫代氨基甲酸酯类似物在所有前列腺癌细胞系中均显示出显着的效力(无论是雄激素受体阳性还是阴性),其细胞毒性IC 50值范围为1.312±0.032μM。治疗第7天时为5.201±0.125μM。与二硫代氨基甲酸钠盐1相比,所有二硫代氨基甲酸酯类似物(2和4a – 4g )在治疗的第7天显示出比化合物1(PC3,IC 50 = 0.087±0.005μM; DU145,IC 50 = 0.079±0.003μM和LNCaP,IC 50 = 0.079± 0.003μM)低的细胞毒性。因此,似乎化合物1的S-烷基化导致更稳定的二
