of alkyl and aryl phosphonate and phosphinate acid-based leaving groups has been developed for utilization in the synthesis of benzoisothiazolone (BIT) inhibitors of human leukocyte elastase (HLE). A number of BITs were synthesized with phosphonate and phosphinate acid-based leaving groups and were found to be potent inhibitors of HLE. Compound 3c with a diethyl phosphonate leaving group is the most
已开发出一类新型的基于烷基和芳基膦酸酯和次膦酸的离去基团,用于合成人白细胞弹性蛋白酶(HLE)的苯并异噻唑酮(BIT)抑制剂。用基于膦酸酯和次膦酸的离去基团合成了许多BIT,发现它们是HLE的有效抑制剂。具有膦酸二乙酯离去基团的化合物3c是该系列中合成的最有效抑制剂,Ki * = 0.035 nM,ED50 = 2.0 mg / kg。
