The role of angiogenesis in tumor growth and metastasis is discussed. The endogenous activators and inhibitors of tumor angiogenesis are presented and their mechanisms of action are reviewed. An overview on angiogenesis as a new potential targed of antitumor therapy is described. The clinical trials of various antiangiogenic agents are briefly summarized and their differential mechanisms of action are discussed.

A number of co-ordination compounds of Ru(III), Rh(III), Pd(II) and Pt(II) with ligands incorporating azole and pyrimidine rings has been synthesized. The in vitro cell proliferation-inhibitory activity of these compounds was examined against human cancer cell lines: A 549 (lung carcinoma), LS-180 (colon cancer) and MCF-7 (breast cancer), using SRB technique. Six out of 13 compounds studied revealed cytotoxic activity in vitro. Inhibitory dose 50% (ID50) was lower than 4 g/ml, which is an activity criterion accepted in conventional in vitro cytotoxic screening tests. Two compounds revealed weak cytotoxic activity with ID50 higher than 4 g/ml and five compounds were inactive.
