8S-Bis(3-methylthiopropanoyl) thiolesters of lipoic acid were synthesized with the carboxyl moiety of lipoate modified as methyl or water soluble choline esters. Evaluation on different cell lines in culture showed that they possessed modest antiproliferative activity. However, the 6-fold decrease in IC50 (from 270 to 45 microM) observed with the water soluble 6S,8S-bis(3-methylthiopropenoyl) thiolester dehydro derivative
合成了硫辛酸的6S,8S-双(3-甲基硫代丙酰基)硫醇酯,并将硫辛酸酯的羧基部分修饰为甲基或水溶性胆碱酯。对培养物中不同细胞系的评估表明它们具有适度的抗增殖活性。然而,在人上皮前列腺癌细胞系(DU145)上使用水溶性6S,8S-双(3-甲基硫代丙烯酰基)硫代酯脱水衍生物观察到的IC50降低了6倍(从270降至45 microM),主张3 -甲硫基丙酰基代谢物,是衍生自蛋氨酸的内源性生长调节(凋亡)化合物。
