Ca V 1.3 L 型钙通道 (LTCC) 已成为帕金森病的潜在靶标,因为钙离子通过该通道流入与线粒体氧化应激的产生有关,从而导致多巴胺能神经元中的细胞死亡。选择性抑制 Ca V 1.3 对其他 LTCC 同种型,尤其是 Ca V 1.2,对于最大限度地减少潜在副作用至关重要。我们最近将嘧啶三酮 (PYT) 鉴定为 Ca V 1.3 选择性支架;在这里,我们报告了 PYTs 与 Ca V 1.3 和 Ca V 1.2 LTCC的构效关系。通过改变 PYT 的环戊基和芳烷基上的取代基,SAR 研究允许表征 CaV 1.3 和 Ca V 1.2 LTCC 结合位点。SAR 还确定了四个重要的部分,它们保留了选择性或增强了结合亲和力。我们的研究代表了 Ca V 1.3 和 Ca V 1.2 LTCC中 PYT 的 SAR 的显着增强,并突出了该系列化合物用于药物开发的先导优化和多样化方面的一些进展。
Lithiated 2-arylpropionitriles were found to react with selenium and carbon monoxide under mild conditions to yield lithium selenocarboxylates. Subsequent alkylation of the selenocarboxylates with methyl iodide gave the corresponding selenol esters in good to high yields.
of aryl halides and activated alkylhalides in DMF in the presence of catalytic amount of NiBr(2)bipy leads to cross-coupling products in good to high yields. The method applies to the synthesis of alpha-aryl ketones, alpha-aryl esters, and allylated compounds from readily available organic halides. Optimization of the process has been obtained by slowly adding the most reactive organic halide (usually
