A series of 3-[3-(dialkylaminomethyl)indol-1-yl]maleimides containing the indole, dihydroindole, mercaptophenol, or tetrahydroquinoline residues at position 4 of the maleimide ring, as well as 3-(dialkylaminomethyl)indole derivatives have been synthesized. Their ability to inhibit in vitro protein kinase C-α (PKC-α) has been studied. Cytotoxicity of new compounds and their ability to constrain activation of multiple drug resistance (MDR) have been studied in the human tumor cell line. Both the toxic and the low-toxic PKC-α inhibitors prevent the activation of MDR in the tumor cells. Among compounds under study, a number of substances have been found that prevent the activation of MDR but do not inhibit PKC-α.
已合成了含有吲哚、二氢吲哚、巯基苯酚或四氢喹啉残基的3-[3-(二烷基氨基甲基)吲哚-1-基]马来酰亚胺,以及3-(二烷基氨基甲基)吲哚衍生物。已研究其抑制体外蛋白激酶C-α(PKC-α)的能力。已研究新化合物的细胞毒性以及其抑制多重耐药性(MDR)激活的能力。有毒和低毒的PKC-α抑制剂均能阻止肿瘤细胞中MDR的激活。在研究中的化合物中,发现了一些物质可以阻止MDR的激活,但不会抑制PKC-α。
