Structure–activity relationship studies of salubrinal lead to its active biotinylated derivative
摘要:
The synthesis and structure-activity relationships (SAR) of salubrinal, a small molecule that protects cells from apoptosis induced by endoplasmic reticulum (ER) stress, are described. It is revealed that the trichloromethyl group greatly contributes to the activity. Based on the SAR results, salubrinal was converted into a biotinylated derivative which retains activity and can be used as a biological tool for target identification. (c) 2005 Elsevier Ltd.

We report a transition-metal-free trans-selective semireduction of alkynes with pinacolborane and catalytic potassium tert-butoxide. A variety of 3-substituted primary and secondary propiolamides, including an analog of FK866, a potent nicotinamide mononucleotide adenyltransferase (NMNAT) inhibitor, are reduced to the corresponding (E)-3-substituted acrylamide derivatives in up to 99% yield with >99:1
我们报道了频哪醇硼烷和催化叔丁醇钾对炔烃的无过渡金属反式选择性半还原。各种 3-取代的一级和二级丙炔酰胺,包括 FK866 的类似物(一种有效的烟酰胺单核苷酸腺苷酸转移酶 (NMNAT) 抑制剂),可被还原为相应的 ( E )-3-取代的丙烯酰胺衍生物,产率高达 99%,且 >99 :1 E / Z选择性。机理研究表明,活化的路易斯酸碱配合物将氢化物转移到α-碳上,然后以反式方式快速质子化。
