such as PK 11195 and Ro 5-4864 were found more than twenty years ago in the course of research on neurobiology. These ligands were instrumental in pointing out an involvement of the peripheral-type benzodiazepine receptor (PBR) in apoptosis processes. With in mind an improvement of the solubility of PK 11195 in biological media, we report here improved reaction conditions for the palladium-based arylation
二十多年前,在神经生物学研究过程中发现了外周型苯并二氮杂receptor受体配体,例如PK 11195和Ro 5-4864。这些配体有助于指出外周型苯并二氮杂receptor受体(PBR)参与凋亡过程。考虑到PK 11195在生物介质中的溶解度有所改善,我们在此报告了烷基1-溴异喹啉-3-羧酸酯及其4-溴喹啉-2-羧酸乙酯异构体基于钯的芳基化反应的反应条件得到了改善。使用[1,1'-双(二苯基膦基)二茂铁]二氯钯作为前催化剂可以大大改善1-芳基异喹啉-3-羧酸盐和4-芳基喹啉-3-羧酸盐的阵列的制备。
