Recently, a series of potent and selective neuronal nitric oxide synthase inhibitors containing two basic nitrogen atoms was reported (Ji, H.; Stanton, B. Z.; Igarashi, J.; Li, H.; Martásek, P.; Roman, L. J.; Poulos, T. L.; Silverman, R. B. J. Am. Chem. Soc. 2008, 130, 3900–3914). In an effort to improve their bioavailability, three compounds (2a–c) were designed with electron-withdrawing groups near
最近,报道了一系列含有两个碱性氮原子的强效选择性神经元一氧化氮合酶抑制剂(Ji, H.;Stanton, BZ;Igarashi, J.;Li, H.;Martásek, P.;Roman, LJ;Poulos , TL; Silverman, RB J. Am. Chem. Soc . 2008 , 130 , 3900–3914)。为了提高其生物利用度,设计了三种化合物(2a - c)在其中一个碱性氮原子附近带有吸电子基团以降低其 p K a. 对这些化合物的抑制研究表明,其中两种化合物不仅保留了早期系列最佳类似物的大部分效力和选择性,而且还显示出基于细胞分析数据的膜渗透性提高。
