III, VB, VI, and XIV), making it a very interesting candidate for situations in which a strong/selective inhibition of certain isozymes is needed. The crystal structure of the hCA II adduct of this sulfonamide revealed interesting interactions between the inhibitor and the enzyme which are quite different from those observed in the adducts of CA II with the structurally related aliphatic derivatives
测试了2-N,N-二甲基氨基-1,3,4-噻二唑-5-甲磺酰胺与12种具有催化活性的哺乳动物碳酸酐酶(CA,EC 4.2.1.1)同工酶CA I-XIV的相互作用。该化合物是CA IV,VII,IX,XII和XIII的有效抑制剂(K(I)为0.61-39 nM),CA II和VA的中效抑制剂(121(438)K(I)s nM)和对其他同工型(CA III,VB,VI和XIV)的弱抑制剂,使其成为需要强烈/选择性抑制某些同工酶的情况下非常有趣的候选药物。该磺酰胺的hCA II加合物的晶体结构揭示了抑制剂与酶之间有趣的相互作用,这与在CA II与结构相关的脂族衍生物zonisamide,2-氨基-1,3,
