Facile Synthesis of cis-Dichloro-(1,4,7-Triazacyclononane) Platinum(II) and its Screening Against Human Ovarian Cancer (SK-OV-3) and Leukemia (K-562) Cell Lines.

A simple method for the preparation of cis-dichloro(1,4,7-triazacyclononane)platinum(II), cis-Pt(tacn)Cl(2) is presented, together with the results of screening the compound against the K-562 (leukemia) and SK-OV-3 (ovarian) human cancer cell lines. While the compound shows no activity against K-562 cells, there is evidence for some cytotoxicity against SK-OV-3. The compound is much less effective than cisplatin, and its limited solubility restricts the useable concentration range.
