Potent inhibition of Janus kinase 3 was found for a series of naphthyl(beta-aminoethyl)ketones (e.g. 7, pIC50 = 7.1+/-0.3). Further studies indicated that these compounds fragment in less than 1 h by retro-Michael reaction in the Jak3 in vitro ELISA assay procedure. The breakdown product of 7, 2-naphthylvinyl ketone (22, pIC50 = 6.8+/-0.3) showed very similar inhibitory activity to 7. Compounds 7 (in
发现对一系列萘基(β-氨基乙基)酮(例如7,pIC 50 = 7.1 +/- 0.3)对Janus激酶3的有效抑制。进一步的研究表明,这些化合物在Jak3体外ELISA分析程序中通过Retro-Michael反应在不到1小时内就会断裂。7、2-萘乙烯基酮的分解产物(22,pIC50 = 6.8 +/- 0.3)显示出与7相似的抑制活性。化合物7(在中性缓冲液中)和22将成为研究Janus酪氨酸的有用药理工具激酶Jak3。
