title: Antitumor activity of conjugates of the oncofetal protein alpha-fetoprotein and phthalocyanines in vitro.
abstract: The several conjugates of aluminium and cobalt complexes of phthalocyanines with human alpha-fetoprotein have been synthesized. Their cytotoxic activity against tumor cells and human peripheral blood lymphocytes was studied. The experimental data demonstrate that the cytotoxic activity of alpha-fetoprotein-phthalocyanine conjugates against three types of tumor cells of various origin is much higher (for aluminium and cobalt complexes more than 1000 and 50 times, respectively) in comparison with phthalocyanines themselves. The application of phthalocyanines as conjugates with alpha-fetoprotein makes it possible to markedly enhance the selective toxicity of phthalocyanines against human tumor cells.
