5,6,7,8-TETRAHYDROPYRIDO[2,3-d]PYRIMIDINES

摘要

Glutamic acid derivatives in which the amino group is substituted with a 2-amino-5,6,7,8-tetrahydropyrido[2,3-d]pyrimidin-6-ylalkyl-Z-carbonyl group, in which Z is a divalent, five-membered, nitrogen-containing heterocyclic ring system optionally containing a sulfur or nitrogen atom as a second hetero ring member, are antineoplastic agents. A typical embodiment is N-{3-[2-(2-amino-4-hydroxy-5,6,7,8-tetrahydropyrido[2,3-d]pyrimidin-6-yl)ethyl]-pyrazol-5-ylcarbonyl}-L-glutamic acid.
