Folinic acid is an adjuvant used in cancer chemotherapy involving the drug methotrexate. It is a 5-formyl derivative of tetrahydrofolic acid and readily converted to other reduced folic acid derivatives, thus, has vitamin activity that is equivalent to that of folic acid. Since it does not require the action of dihydrofolate reductase for its conversion, its function as a vitamin is unaffected by inhibition of this enzyme by drugs such as methotrexate. Synonyms: leucovorin. Grades: >98%. CAS No. 58-05-9. Molecular formula: C20H23N7O7. Mole weight: 473.44.

Leucovorin Calcium
leucovorin calcium is an active metabolite of folic acid (also called folinic acid and citrovorum factor), which does not require metabolism by dihydrofolate reductase, the molecular target of folate antagonist-type chemotherapeutic drugs. Leucovorin calcium counteracts the toxic effects of these medications, 'rescuing' the patient while permitting the antitumor activity of the folate antagonist. This agent also potentiates the effects of fluorouracil and its derivatives by stabilizing the binding of the drug's metabolite to its target enzyme, thus prolonging drug activity.
