Ferrocene incorporated selenoureas as anticancer agents.

For a compound to be a best chemopreventive agent it should be a descent DNA binder and at the same time should be active against any of the three stages of carcinogenesis i.e. cancer initiation, cancer propagation and tumor growth. Most of the problems associated with chemotherapy can be overcome if the chemopreventive agent is active against all the three stages of cancer development. Cancer may be initiated by higher concentration of free radicals, inflammating agents and phase I enzymes (Cytochrome P450) in the body. Cancer propagation can be very efficiently controlled by inducing the phase II enzymes (glutathione S-transferases (GSTs), UDP-glucuronosyl transferases, and quinone reductases) in the body and cancer termination depends on the killing of the faulty cells i.e. cytotoxic actions. This article reports comprehensively the comparative DNA binding studies (with, cyclic voltammetry, UV-vis spectroscopy and viscometry), antioxidant activities (DPPH scavenging), anti-inflammatory activities (nitrite inhibition), phase I enzyme inhibition activities (aromatase inhibition), phase II enzyme induction studies (quinone reductase induction) and cytotoxic studies against neuroblastoma (MYCN2 and SK-N-SH), liver cancer (Hepa 1c1c7) and breast cancer (MCF-7) of seventeen ferrocene incorporated selenoureas.
