A series of O-acyl derivatives of 6-hydroxybenzothiazole-2-sulfonamide (4, L-643,799) was prepared and the potential utility of each series member as a topically active inhibitor of ocular carbonic anhydrase was determined. In vitro studies showed these esters to be substrates for ocular esterases which liberate 4 during corneal translocation. The most interesting series member, 2-sulfamoyl-6-benzothiazolyl
制备了一系列6-羟基苯并噻唑-2-磺酰胺的O-酰基衍生物(4,L-643,799),并确定了每个系列成员作为眼用碳酸酐酶局部活性抑制剂的潜在用途。体外研究表明,这些酯是眼酯酶的底物,它们在角膜移位过程中释放4。发现最有趣的系列成员2,2-磺氨酰基-6-苯并噻唑基2,2-二甲基丙酸酯(22,L-645,151)以4的前药形式存在,当通过分离的白化兔子角膜递送时,其递送能力提高40倍与母体酚4相比。在兔子中的研究表明22是一种有效的局部活性高眼压性碳酸酐酶抑制剂。
