and their inhibitory activity against the human carbonic anhydrase (hCA) isoforms I, II, IX and XII were evaluated. In addition, cytotoxic effects of the synthesized compounds on renal adenocarcinoma (769P), hepatocellular carcinoma (HepG2) and breast adeno carcinoma (MDA-MB-231) cell lines were examined. While the hCA I and II isoforms were inhibited in the micromolar range, the tumor-associated isoform
合成了一系列新的含有三唑部分作为烷基链之间连接基的双香豆素衍生物,并评估了它们对人碳酸酐酶(hCA)同工型I,II,IX和XII的抑制活性。另外,检查了合成化合物对肾腺癌(769P),肝细胞癌(HepG2)和乳腺腺癌(MDA-MB-231)细胞系的细胞毒性作用。虽然hCA I和II亚型在微摩尔范围内受到抑制,但与肿瘤相关的同种型hCA IX和XII在高纳摩尔范围内受到抑制。4-甲基-7-((1-(12-(((2-oxo-2H-chromen-7-yl)oxy)十二烷基)-1H-1,1,2,3-三唑-4-基)甲氧基)-2H -chromen-2-one(5p)对hCA IX的抑制作用最强,Ki为144.6 nM,4-甲基-7-((1-(10-((2-oxo-2H-chromen-7-yl )氧)癸基)-1H-1,2,3-三唑-4-基)甲氧基)-2H-铬-2--2-(5n)表现出最高的hCA XII抑制作用,Ki为71
