4‐diaminopteridine derivatives 10a–10l were prepared in moderate to good yield. Their structures were confirmed by 1H‐NMR and MS spectroscopy, as well as by elemental analysis. Their inhibitory properties against inducible nitric oxide synthase (iNOS) were evaluated in vitro. Biological tests indicated that compound 10a, 10d, 10e, 10h, 10i, and 10l showed potent inhibitory activities similar to that of
