, (2008/06/13)
The present invention relates to pharmaceutically active ornithine compounds, particularly to pharmaceutically acceptable ammonium salts of Nδ-acyl derivatives of Nα(4-amino-4-deoxypteroyl)-L-ornithine compounds; and methods of treatment and pharmaceutical compositions that utilize or comprise one or more of such ammonium salts. The ammonium salts provided by the invention exhibit superior chemical stability than corresponding acidic Nδ-acyl derivatives of Nδ-acyl derivatives of Nα(4-amino-4-deoxypteroyl)-L-ornithine compounds.

Methotrexate (MTX) and aminopterin (AMT) analogues containing L-homocysteic acid or L-cysteic acid in place of L-glutamic acid were synthesized and tested as inhibitors of dihydrofolate reductase from L1210 cells and folyl polyglutamate synthetase from mo
