  摘要：

  The Chemical Universe Generated Databases up to 11 atoms of CNOF (GDB-11) and up to 13 atoms of CNOClS (GDB-13) were used to enumerate analogues of the diamine part of two known alpha 7 nicotinic receptor agonists and construct libraries of virtual analogues of these drugs. The libraries were scored using structure-based (docking to the nicotine binding site of the acetylcholine binding protein 1uw6.pdb) or ligand-based (similarity to the parent drugs) methods, and the top-scoring virtual ligands were inspected for easily accessible synthetic targets. In total, 21 diamines were prepared and acylated with aromatic carboxylic or oxycarbonic acids to produce 85 analogues of the parent drugs. The compounds were profiled by electrophysiology in Xenopus oocytes expressing human nicotinic acetylcholine receptor (nAChR) subtypes alpha 7, alpha 3 beta 2, alpha 4 beta 2, alpha 3 beta 4, or alpha 4 beta 4. Characterization of selected compounds revealed eight inhibitors of the alpha 7 nicotinic receptor and three positive allosteric modulators of the alpha 3 beta 2 nAChR.

  activity of novel small molecule inhibitors of ChoKα. Starting from weakly binding fragments, we describe a structure based lead discovery approach, which resulted in novel highly potent inhibitors of ChoKα. In cancer cell lines, our lead compounds exhibit a dose-dependent decrease of phosphocholine, inhibition of cell growth, and induction of apoptosis at low micromolar concentrations. The druglike lead

  胆碱激酶α（ChoKα）是一种参与磷脂合成的酶，因此在调节细胞增殖，致癌转化和人类致癌作用中起着关键作用。由于ChoKα的几种抑制剂在细胞和动物模型中均表现出抗增殖活性，因此这种新型致癌基因作为一种有前景的癌症治疗小分子靶标最近引起了人们的兴趣。在这里，我们总结了为进一步验证ChoKα作为致癌靶点所做的努力，并探讨了新型的ChoKα小分子抑制剂的活性。从弱结合的片段开始，我们描述了一种基于结构的先导发现方法，该方法导致了新型高效的ChoKα抑制剂。在癌细胞系中，我们的先导化合物显示出剂量依赖性的磷酸胆碱减少，抑制细胞生长，在低摩尔浓度下诱导细胞凋亡。此处介绍的类药物前导系列对于改善细胞效力，药物靶标停留时间和药代动力学参数是可优化的。这些抑制剂不仅可以用来进一步证实ChoKα作为致癌靶标，而且还可以作为新化学物质使用，从而可能导致抗肿瘤剂特异性地干扰癌细胞的代谢。
