Design and synthesis of a novel series of N,4-diphenylpyrimidin-2-amine derivatives as potent and selective PI3Kγ inhibitors
Twenty-one novelN,4-diphenylpyrimidin-2-amine derivatives have been synthesized as PI3Kγ selective inhibitors and compoundC8demonstrated the most potent inhibitory activity against PI3Kγ kinase.
the development of effective cytotoxicagents, a series of oxindole linked indolyl-pyrimidine derivatives were synthesized and characterized by IR, 1H NMR, 13C NMR and Mass spectral analysis. All the newly synthesized target compounds were assessed against PA-1 (ovarian), U-87MG (glioblastoma), LnCaP (prostate), and MCF-7 (Breast) cancer cell lines for their cytotoxic potential, with majority of them

The rhodium(III)-catalyzed C−H bond activation and vinylene transfer of enaminones with vinylenecarbonate have been proposed for the synthesis of substituted 1-hydroxy-2-naphthaldehydes in 49–84% yields. Several preliminary mechanistic studies and hydroxyl-directed derivatization reactions of 1-hydroxy-2-naphthaldehydes were also performed. This method offers an alternative approach for the synthesis
