Title A name given to the resource Synthesis and Biological Evaluation of Novel 8-Morpholinoimidazo[1,2-a]pyrazine Derivatives Bearing Phenylpyridine/Phenylpyrimidine-Carboxamides Creator An entity primarily responsible for making the resource Shan Xu, Chengyu Sun, Chen Chen, Pengwu Zheng, Yong Zhou, Hongying Zhou, Wufu Zhu Description An account of the resource Herein we designed and synthesized three series of novel 8-morpholinoimidazo[1,2-a]pyrazine derivatives bearing phenylpyridine/phenylpyrimidine-carboxamides (compounds 12a–g, 13a–g and 14a–g). All the compounds were evaluated for their IC50 values against three cancer cell lines (A549, PC-3 and MCF-7). Most of the target compounds exhibited moderate cytotoxicity against the three cancer cell lines. Two selected compounds 14b, 14c were further tested for their activity against PI3Kα kinase, and the results indicated that compound 14c showed inhibitory activity against PI3Kα kinase with an IC50 value of 1.25 μM. Structure-activity relationships (SARs) and pharmacological results indicated that the replacement of the thiopyranopyrimidine with an imidazopyrazine was beneficial for the activity and the position of aryl group has a significant influence to the activity of these compounds. The compounds 13a–g in which an aryl group substituted at the C-4 position of the pyridine ring were more active than 12a–g substituted at the C-5 position. Moreover, the cytotoxicity of compounds 14a–g bearing phenylpyrimidine-carboxamides was better than that of the compounds 12a–g, 13a–g bearing phenylpyridine-carboxamides. Furthermore, the substituents on the benzene ring also had a significant impact on the cytotoxicity and the pharmacological results showed that electron donating groups were beneficial to the cytotoxicity.
