Nucleotide pyrophosphatase/phosphodiesterase 1 (NPP1) belongs to the family of ecto-nucleotidases, which control extracellular nucleotide, nucleoside, and (di)phosphate levels. To study the (patho)physiological roles of NPP1 potent and selective inhibitors with drug-like properties are required. Therefore, a compound library was screened for NPP1 inhibitors using a colorimetric assay with p-nitrophenyl
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。
