  Methotrexate analogs. 19. Replacement of the glutamate side-chain in classical antifolates by L-homocysteic acid and L-cysteic acid: effect on enzyme inhibition and antitumor activity

  摘要：

  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 mouse liver. The ID50 against dihydrofolate reductase was comparable for the MTX and AMT analogues (0.04-0.07 microM), whereas the ID50 against folyl polyglutamate synthetase was 3- to 4-fold lower for the AMT analogues (40-60 microM) than for the MTX analogues (100-200 microM). Thus, N10-substitution has a greater effect on binding to folyl polyglutamate synthetase than dihydrofolate reductase. The cytotoxicity of these compounds was assayed in vitro against L1210 cells, and the AMT analogues again proved more potent (ID50 = 0.03-0.05 microM) than the MTX analogues (ID50 = 0.1-0.4 microM). A similarly increased potency was observed for the AMT analogues against L1210 leukemia in vivo. Though differential cell uptake cannot be ruled out as the basis of increased potency, it is possible that part of the activity of the AMT analogues involves interference with the intracellular polyglutamation of reduced folate cofactors, i.e., that they are "self-potentiating antifolates". Of the four compounds reported, the most active was N-(4-amino-4- deoxypteroyl )-L-homocysteic acid, which produced a 138% increase in life span (ILS) in L1210 leukemic mice when given on a modified bid X 10 schedule at a dose of 2 mg/kg. A comparable ILS was obtained with AMT itself at 0.24 mg/kg. Thus, replacement of gamma-CO2H by gamma-SO3H in the side chain does not decrease therapeutic effect. However, a higher dose is required, presumably to offset pharmacological differences reflecting the inability of the sulfonate group to be polyglutamated .

  2-Amino-4-hydroxy-4,5,6,7-tetrahydropyrido\x9b2,3-d!pyrimidine derivatives of aromatic amides, such as a benzamide or thienylcarboxamide in which the amino portion of the amide is other than L-glutamic acid are inhibitors of enzymes which utilize folic acid, in particular glycinamide ribonucleotide formyl transferase. A typical embodiment is N-(N-4-\x9b2-(2-amino-4-hydroxy-5,6,7,8-tetrahydropyrido\x9b2,3-d!pyrimidin-6-y l)ethyl!benzoyl}-L-.gamma.-glutamyl)-D-aspartic acid.
