Metallatranes and hydrometallatranes: their immunotropic and antitumor properties

Resumo

A series of biologically active metallatranes and hydrometallatranes was synthesized via the reaction of biogenic triethanolamine with salts or oxides of the essential metals; their toxicity was determined, and the immunotropic and cytotoxic properties were evaluated. Compounds causing immunostimulatory, immunosuppressive, and also competing effects on the immune response were revealed. A pronounced immunosuppressant, 1-oxovanadatran, exhibits a high and selective cytotoxic effect, inhibiting the growth of B16 melanoma cells by 39–80%, but does not affect the tumor cells of L1210 lymphocytic leukemia, P815 mastocytoma, and Lewis lung carcinoma.
