program, SC-22716 (1, 1-[2-(4-phenylphenoxy)ethyl]pyrrolidine) was identified as a potent inhibitor of LTA(4) hydrolase. Structure-activity relationship (SAR) studies around this structural class resulted in the identification of a number of novel, potent inhibitors of LTA(4) hydrolase, several of which demonstrated good oral activity in a mouse ex vivo whole blood assay.
白三烯B(4)(LTB(4))是促炎性介质,已与包括炎症性肠病(IBD)和牛皮癣在内的多种疾病的发病机制有关。由于LTA(4)水解酶的作用是LTB(4)生产的限速步骤,因此该酶代表了抑制LTB(4)生产的诱人药理学目标。通过内部筛选程序,SC-22716(1,1- [2-(4-苯基苯氧基)乙基]吡咯烷)被确定为LTA(4)水解酶的有效抑制剂。围绕此结构类别的结构活性关系(SAR)研究导致鉴定了许多新型的,有效的LTA(4)水解酶抑制剂,其中几种在小鼠离体全血试验中表现出良好的口服活性。
