Daunomycin-arachidonic acid complex as a potential new antitumor agent

A daunomycin-arachidonic acid complex (DM-C20:4) administered IV had a marked antitumor effect on the intraperitoneal growth of the AFP-producing hepatoma cell line, AH66. However, the daunomycin-arachidic acid (DM-C20:0) saturated fatty acid complex showed only the same antitumor effect on the AH66 cells as free daunomycin. It was demonstrated that the DM-C20:4 preparation maintained its chemical properties for some time in both plasma and liver homogenate.
