The invention relates to compounds and compositions for inhibiting the enzyme fatty acid amide hydrolase (FAAH), the use of the compounds in therapy and, in particular, for treating or preventing conditions whose development or symptoms are linked to substrates of the FAAH enzyme, and methods of treatment or prevention using the compounds and compositions.
N-Aryl and N-alkenyl carbamoyl benzotriazoles were prepared in good to excellent yields from acyl azides and benzotri-azole via Curtiusrearrangement, while N-alkylcarbamoyl benzotriazoles were formed from N-alkanoyl benzotriazoles and sodium azide in one pot. The carbamoyl benzotriazoles can be used as a stable isocyanate alternative, as has been demonstrated by its reaction with amines to synthesize
selectivity and chloro or bromo derivatives 6e-g high selectivity against MCF-7 cells (IC50 0.1–2.6 μM). p-Fluoro derivative 6d, namely 3-(4-fluorophenyl)-1-[(4-[(6-methoxyquinolin-8-yl)amino]pentyl}carbamoyl)amino]urea, is the most promising compound. Further biological experiments showed that 6d affected cell cycle and induced cell death of MCF-7 cell line. Due to its high activity against MCF-7 cell line

synthesized in one-pot from carboxylic acids, diphenylphosphorazidate (DPPA) and benzotriazole (BtH). The reactivity and applications of carbamoyl benzotriazoles were also explored. Carbamoyl benzotriazoles react smoothly with amino acids, hydrazines and alcohols respectively, thus providing facile access to the corresponding ureas, hydrazinecarboxamides and carbamicesters in good to excellent yields
