series of N-benzoylaminoacid analogues was synthesized and obtained compounds were assessed for their ability to inhibit DNMT-dependent DNA methylation in vitro. The biological screening allowed the definition of a set of preliminary structure-activity relationships and the identification of compounds promising for further development. Among the synthesized compounds, L-glutamic acidderivatives 22, 23

Five heretofore undescribed analogues of methotrexate (MTX) and aminopterin (AMT) were synthesized and tested as dihydrofolate reductase (DHFR) inhibitors and tumor cell growth inhibitors. The metaisomer of AMT was obtained from 2,4-diamino-6-(bromomethyl)pteridine and m-(aminobenzoyl)-L-glutamic acid, while the orthoisomer was obtained via the same route by using alpha-methyl gamma-tert-butyl o
