Biomedical chromatography : BMC, 26(1), 76-80 (2011-03-26)
A simple and sensitive HPLC method has been developed for the determination of methotrexate (MTX) and its major metabolites, 7-hydroxymethotrexate (7-OH-MTX) and 2,4-diamino-N(10-) methylpteroic acid (DAMPA), in human plasma. After deproteinization of the plasma with 5% aqueous acetonitrile solution containing

The Journal of pharmacology and experimental therapeutics, 294(3), 894-901 (2000-08-17)
The novel methotrexate (MTX) rescue agent carboxypeptidase-G(2) (CPDG(2)) converts >98% of plasma MTX to 2, 4-diamino-N(10)-methylpteroic acid (DAMPA) and glutamate in patients with MTX-induced renal failure and delayed MTX excretion. DAMPA is eliminated more rapidly than MTX in these patients
D A Cairnes et al.
Therapeutic drug monitoring, 5(3), 363-366 (1983-01-01)
Simple and convenient preparations of two metabolites of the antineoplastic drug methotrexate (MTX) are described. MTX is incubated in a Tris-HCl rabbit liver homogenate to produce 7-hydroxymethotrexate. Filtration, lyophilization, and recrystallization from water gives a chromatographically pure product. Analytical amounts
Rapid quantitation of methotrexate and its metabolites in human serum, urine and bile, using solid-phase extraction and high-performance liquid chromatography.

Therapeutic drug monitoring, 12(2), 191-194 (1990-03-01)
A procedure for the determination of methotrexate in human plasma is reported. The analysis involved extraction of methotrexate as an ion pair in ethyl acetate. Reconstituted residue was analyzed using reverse phase C-18 column and a mobile phase consisting of
