Pyrazoles can be selectively lithiated at different carbons and subsequently react with electrophiles depending on the substitution patterns. 761446-44-0, formula is C10H17BN2O2, Name is 1-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole. 1-Methyl-5-(trifluoromethyl)pyrazole underwent deprotonation and subsequent carboxylation mainly or exclusively at either the 4-position of the heterocycle or at the nitrogen-attached methyl group. SDS of cas: 761446-44-0.
Zhang, Lingzhi;Ju, Qiurong;Sun, Jinjin;Huang, Lei;Wu, Shiqi;Wang, Shuping;Li, Yin;Guan, Zhe;Zhu, Qihua;Xu, Yungen research published 《 Discovery of novel dual extracellular regulated protein kinases (ERK) and phosphoinositide 3-kinase (PI3K) inhibitors as a promising strategy for cancer therapy》, the research content is summarized as follows. The scaffold-hopping generation of a series of 1H-pyrazolo[3,4-d]pyrimidines I (R1 = 2-methylpyridin-4-yl, 1-methyl-1H-pyrazol-4-yl; R2 = Bn, cyclopentyl) dual ERK/PI3K inhibitors was reported. 1-(7-(1H-Pyrazol-4-yl)pyrido[3,2-d]pyrimidin-2-yl)-3-cyclopentylurea was the most promising candidate, with potent inhibitory activities against both ERK2 and PI3Kα which displays superior anti-proliferative profiles against HCT116 and HEC1B cancer cells. Meanwhile, 1-(7-(1H-pyrazol-4-yl)pyrido[3,2-d]pyrimidin-2-yl)-3-cyclopentylurea possessed acceptable pharmacokinetic profiles and showed more efficacious anti-tumor activity than GDDC-0980 and the corresponding drug combination (BVD-523 + GDDC-0980) in HCT-116 xenograft model, with a tumor growth inhibitory rate of 51% without causing observable toxic effects. All the results indicated that 1-(7-(1H-pyrazol-4-yl)pyrido[3,2-d]pyrimidin-2-yl)-3-cyclopentylurea was a highly effective anticancer compound and provided a promising basis for further optimization towards dual ERK/PI3K inhibitors.
