and its C8-C9 conformationally restricted E- and Z-isomers (6 and 7) were designed and synthesized in order to investigate the effect of incorporating a methyl group at the C9 position and of conformationalrestriction at the C8-C9 bridge of N-[4-[2-(2,4-diaminofuro[2, 3-d]pyrimidin-5-yl)ethyl]benzoyl]-L-glutamic acid (1) with respect to dihydrofolate reductase (DHFR) inhibitoryactivity as well as antitumor
