Inhibitors of human nitric oxide synthase isoforms with the carbamidine moiety as a common structural element
摘要:
Identification of potent and selective inhibitors of inducible nitric oxide synthase (NOS) is of great interest because of their therapeutic potential for treatment of diseases mediated by excess production of nitric oxide. We present here a comparison of potency and selectivity for amino acid and nonamino acid based compounds as inhibitors of human inducible, human endothelial constitutive and human neuronal constitutive NOS isoforms. In addition, a novel series of substituted amidines has been identified as NOS inhibitors. 2-Methylthioacetamidine and 2-thienylcarbamidine were the most potent of the series examined with IC50 values of 3.9 and 2.9 mu M for human neuronal constitutive NOS. Cyclopropylcarbamidine and 2-thienylcarbamidine were the most potent inhibitors for human inducible NOS with IC50 values of 5.2 and 6.5 mu M, respectively. These substituted amidines represent a new class of NOS inhibitors acid provide a foundation for potential therapeutic agents. Copyright (C) 1996 Elsevier Science Ltd

CuI/L5 (N,N′-dimethylethylenediamine) proves to be an efficient catalyst system for the amination of arylhalides with guanidines. The same catalyst system is then successfully applied to the one-step synthesis of 1-H-2-amino-benzimidazoles through tandem aminations of 1,2-dihaloarenes in modest yields. This methodology is also applicable for the preparation of 1-H or 1-substutituted 2-aryl- or 2-alkyl-benzimidazoles
事实证明,CuI / L5(N,N'-二甲基乙二胺)是一种用于将芳基卤化物与胍胺化的有效催化剂体系。然后将相同的催化剂体系成功地通过1,2-二卤代芳烃的串联胺化以适度的产率成功地一步合成1- H -2-氨基-苯并咪唑。该方法学也可用于制备1- H或1-取代的2-芳基-或2-烷基-苯并咪唑。
