the derivatives equaled or exceeded the efficacy shown by SHetA2. Compounds 1a-d (series 1), lacking a methyl on the Ring A nitrogen and the gem-dimethyls on the adjacent carbon, showed only weak activity. Salt 2, the quaternized N,N-dimethyl iodide salt analog of 1a, also possessed very modest growth inhibition in the cell line studied. Series 3 compounds, which had a C3 ketone and an N-methyl replacing
SHetA2(NSC 721689)是我们的领先Flex-Het抗癌药,由硫代色烷(A环)和4-硝基苯基(B环)通过硫脲桥连接而成。在这项工作中,已经制备了一系列新的类似物,它们具有通过尿素或硫脲接头与4-取代的苯基(环B)连接的四氢喹啉(THQ,环A)单元,并相对于SHetA2进行了结合亲和力评估。 mortalin和抑制A2780卵巢癌细胞。六种衍生物等于或超过了SHetA2所示的功效。化合物1a-d(系列1)在A环氮原子上缺少甲基,而在相邻碳原子上缺少宝石-二甲基,则仅显示出较弱的活性。盐2,1a的季铵化N,N-二甲基碘盐类似物,在所研究的细胞系中也具有非常适度的生长抑制作用。系列3化合物 碳原子数为3的酮和N-甲基取代了环A中的硫的化合物最为成功。化合物3a [环A = 1,2,2,4,4-五甲基-3-氧代-1,2,3,4-四氢喹啉-6-基;尿素接头; B环= 4-硝基苯基]的效能(IC50
