Metabolite Identification
Common Name10-Formyldihydrofolate
Description10-formyldihydrofolate is a folate compound that has not been found as a component of intracellular folates in normal tissues but has been identified in the cytosol of methotrexate (MTX)-treated MCF-7 breast cancer cells and normal human myeloid precursor cells. The origin of 10-formyldihydrofolate remains an enigma. Its appearance only in the extracts from MTX-treated cells is not consistent with a simple oxidation of lO-formyl-H4folate during the extraction procedure. This, however, does not exclude the occurrence of spontaneous oxidation of 10-formyl-H4folate within the intact cells prior to the folate extraction. (PMID: 3366769 ).
