  摘要：

  核苷酸焦磷酸酶/磷酸二酯酶1（NPP1）属于胞外核苷酸酶家族，可控制细胞外核苷酸，核苷和（di）磷酸盐的水平。为了研究具有药物样特性的NPP1强效和选择性抑制剂的（病理）生理作用。因此，使用比色测定法以对硝基苯基5'-胸苷单磷酸酯（p -Nph-5'-TMP）作为人工底物，筛选化合物库中的NPP1抑制剂。这导致发现2-（3 H-咪唑并[4,5 - b ]吡啶-2-基硫基）-N-（3,4-二甲氧基苯基）乙酰胺（5a）为具有K i的命中化合物。值为217 nM。随后的结构-活性关系研究导致了嘌呤和咪唑并[4,5- b ]吡啶类似物的开发，用p -Nph-5'-进行测定具有高抑制力（K i值分别为5.00 nM和29.6 nM）。以TMP为底物。出乎意料的是，与ATP作为底物相比，测试时这些化合物的效力明显较低，K i值在低微摩尔范围内。对原型抑制剂的抑制机理进行了研究，发现该抑制剂与两种底物都具有竞争性。

  Preparations of 2-hydroxy- and 2-mercapto-1H-imidazo[4,5-blpyrazines from pyrazine-2,3-diamines are described. Methylation of 1H-imidazo[4,5-b]pyrazine-2(3H)-thione with methyl iodide and diazomethane gave some S, N1, N3 and N4 methyl derivatives; and 1H-imidazo[4,5-b]pyrazin- 2(3H)-one with diazomethane gave products which involved O, N1, N3 and N4 methylation. These products showed slight activity as amplifiers of phleomycin but the benzothiazoles (10b) and (10c) (as hydrobromides) showed three and four star activity respectively.
