derivatives were assayed as inhibitors of the zinc enzyme carbonic anhydrase (CA) and more precisely of three of its isozymes, CA I, II (cytosolic forms), and IV (membrane-bound form), involved in important physiological processes. Efficient inhibition was observed against all three isozymes and especially against CA II and IV (in the nanomolar range), the two isozymes known to play a critical role
26种含氨基,亚氨基,肼基或羟基的芳香族/杂环磺酰胺与Boc-Gly,Boc-Sar,TrS-Crt或Boc-Gly-Gly(Sar =肌氨酸,N-Me-Gly; Crt =肌酸,N-ami肌氨酸; TrS =三苯硫基; Boc =叔丁氧基羰基),在存在碳二亚胺衍生物的情况下,除去保护基团后提供了一系列水溶性化合物(作为强酸的盐,如盐酸,三氟乙酸或三氟甲磺酸) )。分析了新衍生物作为锌酶碳酸酐酶(CA)的抑制剂,更准确地说是涉及重要生理过程的三种同工酶CA I,II(胞质形式)和IV(膜结合形式)的抑制剂。观察到对所有三种同工酶,特别是对CA II和IV(在纳摩尔范围内)的有效抑制,已知这两种同工酶在眼睛睫状突中的房水分泌中起关键作用。当观察到许多强抑制剂和持久的眼内压(IOP)降低时,一些合成的最佳抑制剂以2%水溶液的形式应用于正常血压或青光眼性白化病兔子的眼睛。因此,赋予这些磺酰胺CA
