The preparation of stable complexes between the N7-[2-(2-pyridyl)ethyl] and N7-(2-piperazinylethyl) derivatives of mitomycin C and metal ions such as Cu(II), Zn(II), and Pt(II) was accomplished. Mitomycin C did not form stable complexes, but it rearranged to a mitosene capable of complex formation. Some of these complexes had antitumor activity in mice. However, they were less active than mitomycin C. Weak associations between mitomycin C and metal ions were demonstrated by 13C and 15N NMR spectrometry.
