beta-Elemene monosubstituted amine, ether and rhenium coordinated complex were synthesized. Their structures were characterized by IR, H-1 NMR, C-13 NMR, HRMS or EA. Their IC50 on HeLa cell lines, cell cycle and protein expression of G(1) phase (Cyclin D-1, Rb, P-Rb) were detected respectively by the method of WST-1, Flow Cytometry and Western Blot. The Results showed that the in vitro anti-proliferative activity of beta-elemene monosubstituted amine and Re(CO)(3)-beta-elemene derivatives in human cervix epitheloid carcinoma HeLa cells were improved significantly compared with both of ether derivatives and parent beta-belemene. These derivatives could reduce Rb phosphorylation and cyclin D1 protein expression to arrest the cell cycle at G1 phase. (C) 2008 Elsevier Ltd. All rights reserved.
