Treatment of N-alpha-Cbz-N-epsilon-(2-hydroxyethylaminothiocarbonyl)-L-lysine N-(2-hydroxyethyl)amide with boiling hydrochloric acid gave N-epsilon-(4,5-dihydrothiazol-2-yl)-L-lysine. This was a weak and non-isoform selective inhibitor of NOS, whereas N-epsilon-aminothiocarbonyl-L-lysine and its methyl ester were potent, with IC50 = 13 and 18 muM, respectively, against human iNOS and IC50 = 3 and 8 muM, respectively, against rat nNOS. Time dependence was observed for inhibition of nNOS by the ester. (C) 2003 Elsevier Ltd. All rights reserved.
