dimethylamino or amino acyl) being the most active ones, and the derivatives incorporating such bulky moieties (n-propyl, n-butyl, diethylaminoethyl, piperazinylethyl, pyridoxal amine or phenoxy) being less effective hCA I, II and IX inhibitors. Some of the new derivatives also showed selectivity for inhibition of hCA IX over hCA II (selectivity ratios of 23.33-32.00), thus constituting excellent leads
据报道,一系列新的芳香族苯磺酰胺分子中包含1,3,5-三嗪部分。通过氰尿酰氯与磺胺,高磺胺或4-氨基乙基苯磺酰胺的反应获得该系列。随后使所制备的二氯三嗪基-苯磺酰胺与各种亲核试剂,例如氨,肼,伯胺和仲胺,氨基酸衍生物或苯酚反应,将其衍生化。测试了掺入三嗪基部分的磺酰胺文库对三种生理相关的碳酸酐酶(CA,EC 4.2.1.1)同工酶,胞质hCA I和II以及跨膜,与肿瘤相关的hCA IX的抑制作用。新化合物以31-8500 nM的抑制常数抑制hCA I,hCA II的抑制常数为14-765 nM,hCA IX的抑制常数为1.0-640 nM。在这类CA抑制剂中,结构活性关系简单明了,相当简单,其中在三嗪环上结合有紧密部分的化合物(例如氨基,肼基,乙基氨基,二甲基氨基或氨基酰基)是活性最高的化合物,这样的大体积部分(正丙基,正丁基,二乙基氨基乙基,哌嗪基乙基,吡ido醛胺或苯氧基)是不太有效的hCA
