Role of bio-metal Fe(III) in anticancer behaviour of tamoxifen.

ABSTRACT

Physicochemical, microbial and pharmacological studies on Fe (III)--Tamoxifen complex have been carried out in solid and aqueous phases. On the basis of elemental analysis, polarographic studies, amperometric titrations and IR spectral studies the probable formula for the complex has been worked out to be 11, Fe(III)--Tamoxifen. A tentative structure has been suggested to the complex. The metal ligand interaction has been studied using polarographic method at 27 degrees +/- 1 degree C and at ionic strength of mu = 1.0 (KCl). Microbial studies on the complex was carried out against various pathogenic bacteria and fungi using Raper's method. Mouse sarcoma cell line 180 and Balb/C mice were used for the anticancer screening of solid complex, in vitro and in vivo, respectively. The results of microbial and pharmacological studies with the MDrug complex revealed that the complex is more potent as compared to the pure drug as regards to its anticancer activity. As such Fe (III) Tamoxifen complex may be recommended to the therapeutic experts for its possible use as more potent anticancer drug.
