  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。

  been validated as an anticancer target in mantle cell lymphoma. In this study, we found a potent and selective PRMT5 inhibitor by performing structure-based virtual screening and hit optimization. The identified compound 17 (IC50 = 0.33 μM) exhibited a broad selectivity against a panel of other methyltransferases. The direct binding of 17 to PRMT5 was validated by surface plasmon resonance experiments

  PRMT5在多种细胞过程中起着重要作用，并在几种人类恶性肿瘤中被上调。此外，PRMT5已被确认为套细胞淋巴瘤的抗癌靶标。在这项研究中，我们通过执行基于结构的虚拟筛选和命中优化，发现了一种有效的选择性PRMT5抑制剂。鉴定出的化合物17（IC 50 = 0.33μM）对一组其他甲基转移酶表现出广泛的选择性。通过表面等离振子共振实验验证了17与PRMT5的直接结合，K d为0.987μM。动力学实验表明17是除底物以外的SAM竞争性抑制剂。另外17提示对MV4-11细胞具有选择性的抗增殖作用，进一步的研究表明，细胞抗肿瘤活性的机制是由于PRMT5介导的SmD3甲基化的抑制。17可能是一种有前途的先导化合物，可以进一步了解PRMT5，并可能有助于开发白血病适应症的治疗方法。
