Antiproliferative Evaluation of (E)-3-(3-(Allyloxy)-2-Methoxyphenyl)-1-(2,4,6-Trimethoxyphenyl)Prop-2-En-1-One as a Novel Apoptosis Inducer Against Prostate Cancer PC-3 Cells

Abstract

(E)-3-(3-(Allyloxy)-2-methoxyphenyl)-1-(2,4,6-trimethoxyphenyl)prop-2-en-1-one displayed potent antiproliferative activity against the PC-3 cell line. For colony assay, it can inhibit the colony formation at a concentration of 10 μM. Morphological changes of PC-3 cells were determined using DAPI (4′,6-diamidino-2-phenylindole) staining and chromatin condensation. Treatment with this compound at 10 μM induced apoptosis from 2.0% to 30.4% compared with control according to flow cytometry analysis. It also induced the downregulation of apoptosis-related markers Bcl-2 and XIAP (X-linked inhibitor of apoptosis protein). However, treatment with NAC (N-acetyl-L-cysteine) almost completely attenuated chalcone-induced cell inhibition and cell apoptosis in PC-3 cells.
