  • Title: Potentiation of the cytotoxic action of melphalan and "activated" cyclophosphamide against cultured tumor cells by centrophenoxine.
    Author: Sladek NE.
    Journal: J Pharmacol Exp Ther; 1977 Jan; 200(1):17-24. PubMed ID: 319221.
    Abstract:
    Centrophenoxine, without antitumor activity itself, enhanced the cytotoxic action of melphalan and "activated" cyclophosphamide against mouse P388 lymphoma and rat W256 carcinosarcoma cells growing in static suspension culture. The concentration of alkylating agent required for 99% cell-kill was approximately halved when centrophenoxine was also present during exposure to the antitumor drug. Maximum potentiation by centrophenoxine of the cytotoxic action of melphalan occurred when cells were exposed to the two agents simultaneously; little or no potentiation was observed when cells were exposed to centrophenoxine before or after exposure to the alkylating agent.
