the amidine nitrogen and phenyl ring to give N-(3-(aminomethyl)phenyl)acetamidine (14) dramatically altered the selectivity to give a neuronal selective nitric oxide synthase (nNOS) inhibitor. Part of this large shift in selectivity was due to 14 being a rapidly reversible inhibitor of iNOS in contrast to the essentially irreversible inhibition of iNOS observed with 13. Structure-activity studies revealed
与内皮和诱导型亚型相比,可能需要选择性抑制一氧化氮合酶(NOS)的神经元亚型,以治疗由一氧化氮过量产生引起的神经系统疾病。最近,我们将N-(3-(氨基甲基)苄基)乙am(13)描述为一种缓慢,紧密结合的抑制剂,对人诱导型一氧化氮合酶(iNOS)具有高度选择性。除去the氮和苯环之间的单个亚甲基桥以得到N-(3-(氨基甲基)苯基)乙am(14)极大地改变了选择性,从而得到了神经元选择性一氧化氮合酶(nNOS)抑制剂。选择性大幅度变化的部分原因是14是iNOS的快速可逆抑制剂,而13观察到的iNOS基本上不可逆的抑制。结构活性研究表明,与芳香环相连的碱性胺官能团和空间紧凑的idine是此类NOS抑制剂的关键药效团。用N-(3-(氨基甲基)苯基)-2-呋喃基idine啶(77)可获得最大的nNOS抑制能力(Ki-nNOS = 0.006 microM; Ki-eNOS = 0.35 microM;
