On October 1, 2020, Wang, Shuai; Ma, Xu-Bin; Yuan, Xiao-Han; Yu, Bin; Xu, Yi-Chao; Liu, Hong-Min published an article.Product Details of 10472-24-9 The title of the article was Discovery of new [1,2,4] Triazolo[1,5-a]Pyrimidine derivatives that Kill gastric cancer cells via the mitochondria pathway. And the article contained the following:
A novel series of [1,2,4]triazolo[1,5-a]pyrimidine-based compoundsI [R1 = benzyl, 4-fluorobenzyl, 4-chlorobenzyl, etc.; R2 = Me, Et, Ph; R3 = H, Me] and II [R4 = Ph, (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl), (4-(3-(5-bromo-2-pyridyl)prop-2-enoyl)phenyl), etc.] were synthesized and tested their anti-proliferation efficacy against gastric cancer cell line MGC-803. Among them, compounds II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl), (4-(3-(5-bromo-2-pyridyl)prop-2-enoyl)phenyl)] inhibited gastric cancer cells at micromolar level. Compound II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl)] caused G2/M arrest and induced mitochondria-dependent apoptosis in MGC-803 and SGC-7901. However, inhibiting apoptosis pathway cannot prevent the inhibitory activity of compound II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl)] against gastric cancer cell. To our surprising, ROS level was increased by compound II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl)] and elevation of ROS could be rescued by NAC. In accordance with that, NAC absolutely prevented the anti-proliferation efficacy of compound 4o. We further found that autophagy inhibitor CQ rather than 3-MA partially reversed inhibitory activity of compound II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl)] in MGC-803 cells. Taken together, compound II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl)] exhibited its anti-proliferative activity via increasing ROS level and inducing autophagy, thus leading to apoptosis of gastric cancer cells. Therefore, compound II [R4 = (4-(3-(6-bromo-2-pyridyl)prop-2-enoyl)phenyl)] may support further development of lead compounds for gastric cancer therapy via mitochondria pathway. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Product Details of 10472-24-9
