Isothiocyanates were synthesized by reactions between primary amines and CS2 in the presence of 4-dimethylaminopyridine as a catalyst and tert-butyl hydroperoxide as an oxidant. Various aryl, benzyl, alkyl, and hydroxyl amines were transformed into the corresponding isothiocyanates in 41–82% yields.

Plant samples of Hornungia petraea were analyzed for glucosinolate (GLS) autolysis metabolites for the first time. GC-MS analysis of the autolysate and the synthesis of a series (12 compounds) of possible glucosinolate breakdown products revealed/corroborated the presence of glucoaubrietin, glucolimnanthin, glucolepigramin and glucotropaeolin in this species as the most likely "mustard oil" precursors. GLS degradation products identified in the autolysate of H. petraea, benzyl isothiocyanate, 3- and 4-methoxybenzyl isothiocyanate, along with several other structurally related compounds were evaluated for antimicrobial activity in order to possibly pinpoint the role of the latter secondary metabolites in the plant tissues. The assays showed a very high antibacterial activity of the tested isothiocyanates against Sarcina lutea and an antifungal effect against Aspergillus fumigatus and Candida albicans with MIC values in the order of 1 μg/ml value.

Inhibition of the isoforms of nitric oxide synthase (NOS) has important applications in therapy of several diseases, including cancer. Using 1400W [N-(3-aminomethylbenzyl)acetamidine], thiocitrulline and N δ-(4,5-dihydrothiazol-2-yl)ornithine as lead compounds, series of N-benzyl- and N-phenyl-2-amino-4,5-dihydrothiazoles and thioureas were designed as inhibitors of NOS. Ring-substituted benzyl and phenyl isothiocyanates were synthesised by condensation of the corresponding amines with thiophosgene and addition of ammonia gave the corresponding thioureas in high yields. The substituted 2-amino-4,5-dihydrothiazoles were approached by two routes. Treatment of simple benzylamines with 2-methylthio-4,5-dihydrothiazole at 180 °C afforded the corresponding 2-benzylamino-4,5-dihydrothiazoles. For less nucleophilic amines and those carrying more thermally labile substituents, the 4,5-dihydrothiazoles were approached by acid-catalysed cyclisation of N-(2-hydroxyethyl)thioureas. This cyclisation was shown to proceed by an SN2-like process. Modest inhibitory activity was shown by most of the thioureas and 4,5-dihydrothiazoles, with N-(3-aminomethylphenyl)thiourea (IC50=13 μM vs rat neuronal NOS and IC50=23 μM vs rat inducible NOS) and 2-(3-aminomethylphenylamino)-4,5-dihydrothiazole (IC50=13 μM vs rat neuronal NOS and IC50=19 μM vs human inducible NOS) being the most potent. Several thioureas and 4,5-dihydrothiazoles were found to stimulate the activity of human inducible NOS in a time-dependent manner.
