“ Folic acid , because it can also potentially be metabolized to methylenetetrahydrofolate, was evaluated for its ability to potentiate FU antitumor activity in a dietary folic acid restricted murine model.”
“These results indicate that folic acid is a potent modulator of FU activity and could be considered as an alternative to leucovorin in the clinical setting.”
“While FU alone suppressed growth 25%, folic acid in combination with FU increased growth suppression to over 70%.”
