compounds in which 5-chloroanthranilic acid was bound to a variety of highly lipophilic moieties with appropriate linkers was investigated. As the result it appeared that some of the derivatives possessing aryl- or heteroaryl-substituted phenyl groups in the acyl chain had potent in vitro PAI-1 inhibitory activity. Oral absorbability of typical compounds was also evaluated in rats, and compounds 40,
通过对N-酰基-5-氯邻氨基苯甲酸衍生物的结构-活性关系研究发现了新型的具有显着改善的口服生物利用度的纤溶酶原激活物抑制剂-1(PAI-1)抑制剂。由于亲脂性N-酰基对于邻氨基苯甲酸衍生物强烈抑制PAI-1似乎很重要,因此研究了其中5-氯邻氨基苯甲酸与各种具有适当连接基的高度亲脂性部分结合的化合物的合成。结果表明,某些在酰基链上具有被芳基或杂芳基取代的苯基的衍生物具有有效的体外PAI-1抑制活性。还评估了大鼠中典型化合物的口服吸收能力,化合物40,55,60和76被选择具有相互不同的化学结构,用于进一步药理评价。
