Design, Synthesis, and Evaluation of the Anticancer Properties of a Novel Series of Imidazolone Fused Pyrazolo[1,5-a]pyrimidine Derivatives
2017
A novel series of imidazolone fused pyrazolo[1,5-a]pyrimidine derivatives has been designed and synthesized using a convergent approach, and the structures of these compounds were confirmed by 1H NMR, 13C NMR, ESI-MS, and IR analyses. These new compounds were tested for their in vitro antiproliferative activity using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Out of the 20 derivatives prepared in the current study, compounds 8h, 8n, and 8r exhibited good anticancer activities tested against HeLa cells and HepG2 cells. However, the in vitro anticancer activity of compound 8r against HeLa, HepG2, and MCF-7 cell lines is superior to the marketed drugs Paclitaxel and SAHA.
