High-performance liquid chromatography of methotrexate analogs containing terminal lysine or ornithine and their
Analytical Biochemistry
|January 1, 1983
Abstract:
A procedure utilizing a reverse-phase semipreparative high-performance liquid chromatography column and a binary solvent system consisting of trifluoroacetic acid and 1-propanol has been developed for the semipreparative scale purification and analytical identification of four newly synthesized analogs of methotrexate. The methotrexate analogs containing a lysine or an ornithine residue in place of a terminal glutamate residue together with their respective dansyl derivatives were purified in milligram quantities by the procedures described.
