Folitixorin  (Synonyms: 5,10-Methylenetetrafolate; ANX-510 free acid)

Folitixorin (5,10-methylenetetrahydrofolate) is a cofactor and an analog of leucovorin. Folitixorin is a promising agent for modulation of 5-FU cytotoxicity in adjuvant cancer research^[1][2].

5,10-methylenetetrahydrofolate reductase (MTHFR) catalyzes the conversion of 5,10-methylenetetrahydrofolate into 5-methyltetrahy-drofolate, which is the major circulating form of folate^[3].

A colon adenocarcinoma cell suspension is inoculated intrahepatically in a rodent experimental model. Intravenous 5-FU (30 mg/kg) in combination with Folitixorin (15 mg/kg or 30 mg/kg) is administered after 1, 2, 3, 4 and 7 days. 5-FU in combination with Folitixorin (regardless of folate-dose) eliminats tumor take^[1].
