Abstract
The thiosemicarbazone derivative of 9,10-phenanthrenequinone, 1, and its metal complexes were synthesized. The X-ray crystal structure for 1 confirms the presence of the E tautomeric arrangement in this compound. Its copper complex shows 1:1 stoichiometry while nickel and cobalt compounds show 1:2 stoichiometry. The X-ray crystal structure of the nickel complex indicates two tridentate ligands coordinating in the thiolato form yielding an octahedral geometry for the 'mer' isomer. The copper complex exhibits maximum antiproliferative activity against human breast cancer cell-line, T47D probably due to inhibition of steroid binding to the cognitive receptor or by preventing dimerization of the estrogen receptor.
