An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.

has been found to be a potentinhibitor of both the human constitutive and inducible isoforms of nitricoxidesynthase. A series of substituted N-phenylisothiourea analogues was synthesized to investigate the structure-activity relationship of this class of inhibitor. Each analogue was evaluated for human isoform selectivity. One analogue, S-ethyl N-[4-(trifluoromethyl)phenyl]isothiourea (39), exhibited
