Phosphoinositide-3-kinase (PI3K) is an important target for cancer therapeutics due to the deregulation of its signaling pathway in a wide variety of human cancers. We describe herein a novel series of imidazo[1,2-a]pyrazines as PI3K inhibitors.

Page/Page column 49; 241; 242, (2018/06/26)
The first aspect of the invention relates to a phosphoinositide 3-kinase inhibitor for use in the treatment or prevention of a disease or condition associated with the expression of peroxisome proliferator-activated receptor gamma coactivator 1-α (Pgd1α) and/or uncoupling protein 1 (Thermogenin/Ucp1) in brown adipocytes. The disease or condition may be positive energy imbalance-associated, for example, obesity, an obesity-associated disease or condition, steatosis and biological aging (performance aging). Another aspect of the invention provides the use of a phosphoinositide 3-kinase inhibitor for promoting weight loss in an individual.

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.
