Abstract :
The protonation constants and the stability constants for the formation of copper (II) complex of the ligand [1,4,7] Triazecan-9-ol (L) were presented. Antitumor activity of CuL complex was reported. Preliminary pharmacological tests showed that it had antitumor activity against HXO-RB44 and BEL-7402 cell lines in vitro. Nuclei of [CuL]-stimulated BEL-7402 cells clearly exhibited condensation and break down into chromatin clumps typical of apoptosis. Also it exhibited perturbation effects to BEL-7402 cell lines cycle and further studies showed that it could cleave supercoiled DNA (pBR 322) to nicked and linear DNA.
