| Abstract: | This report describes a highly active chemotherapeutic drug combination, consisting of W-(phosphonacetyl)-L-aspartate plus 6-methylmercaptopurine riboside plus 6-aminonicotinamide plus 5-fluorouracil, in CD8F1 mice bearing spontaneous, autochthonous, breast tumors or first-passage advanced transplants of these spontaneous tumors. The combination and sequence of administration of these drugs were selected on the basis of known potentiating biochemical interactions. High performance liquid chromatography and nuclear magnetic resonance spectroscopy measurements of biochemical changes resulting from treatment with AKphosphonacetylH-aspartate plus 6-methylmercaptopurine riboside plus 6-aminonicotinamide indicated a severe depletion of cellular energy levels in the treated tumors. 6-Aminonicotinamide produced a severe block of the pentose shunt, and 5-fluorouracil severely inhibited both thymidylate synthase and thymidine kinase in the treated tumors. This quadruple drug combination, administered on a 10-11-day schedule, produced an impressive partial tumor regression rate of 67% of large, spontaneous, autochthonous, murine breast tumors and a tumor regression rate of 74% of first-passage transplants of the spontaneous breast tumors. © 1992, American Association for Cancer Research.
