Eur J Med Chem. 2017 Sep 29:138:140-151. doi: 10.1016/j.ejmech.2017.06.026. Epub 2017 Jun 15.

Abstract

A series of dihydropyrimidine (DHPM) derivatives bearing 1,3,4-oxadiazole moiety was designed and synthesized as monastrol analogues. The new compounds were screened for their cytotoxic activity toward 60 cancer cell lines according to NCI (USA) protocol. Seven compounds were further examined against the most sensitive cell lines, leukemia HL-60(TB) and MOLT-4. The most active compounds were 9m against HL-60(TB) (IC50 = 56 nM) and 9n against MOLT-4 (IC50 = 80 nM), more potent than monastrol (IC50 = 147 and 215 nM, respectively). Cell cycle analysis of HL-60(TB) cells treated with 9m and MOLT-4 cells treated with 9n showed cell cycle arrest at G2/M phase and pro-apoptotic activity as indicated by annexin V-FITC staining.

Keywords: 1,3,4-Oxadiazole; Anticancer activity; Apoptosis; Cell cycle arrest; Dihydropyrimidine.
