Nitric oxide (NO), a mediator of various physiological and pathophysiological processes, is synthesized by three isozymes of nitric oxide synthase (NOS). In developing candidate clinical drugs, it is very important not to inhibit endothelial NOS, because it plays an important role in maintaining normal blood pressure and flow. Here, we describe the design, synthesis and human NOS-inhibitory activities
一氧化氮(NO)是多种生理和病理生理过程的介体,由一氧化氮合酶(NOS)的三种同工酶合成。在开发候选临床药物中,不抑制内皮型NOS非常重要,因为它在维持正常的血压和流量中起着重要的作用。在这里,我们描述了基于S-甲基-L-异硫瓜氨酸的3-取代精氨酸类似物的设计,合成和人类NOS抑制活性。具有S-甲基异硫脲部分的3R *-甲基化合物4抑制nNOS和iNOS,但不抑制eNOS(IC(50)> 1 mM)。然而,尽管LN-亚氨基乙基鸟氨酸(L-NIO)有效地抑制了全部三个,但带有5-亚氨基乙基部分的3R *-甲基化合物7没有抑制任何NOS同工酶。
