bromine and compound 13 with fluorine substituents can be considered as the leader compounds of the series because of the lowest Ki values in series to make further detailed carbonic anhydrase inhibiton studies.
成功合成了4-(3-(4-取代-苯基)-5-苯基-4,5-二氢-1H-吡唑-1-基)苯磺酰胺(9-16),并通过1H NMR证实了其化学结构, 13 C NMR和HRMS光谱。研究了化合物的碳酸酐酶I和II抑制作用。化合物对hCA I的Ki值在316.7±9.6-533.1±187.8 nM范围内,对hCA II同工酶的Ki值在412.5±115.4-624.6±168.2 nM范围内。而参考化合物乙酰唑酰胺的Ki值分别对hCA I和hCA II同工酶分别为278.8±44.3 nM和293.4±46.4 nM。具有溴的化合物14和具有氟取代基的化合物13可以被认为是该系列的主要化合物,因为串联的最低Ki值可以进行更详细的碳酸酐酶抑制剂研究。
