New N-hydroxyamides of n-alkyl carboxylic acids omega substituted with suitable tricyclic systems characterised by a central 7-membered ring, having activity as inhibitors of histone deacetylase (HDAC).
Histonedeacetylases are promising molecular targets for the development of antitumor agents. A novel series of histonedeacetylaseinhibitors of the hydroxamic acid type were synthesized for structure-activity studies. Thirteen tricyclic dibenzo-diazepine, -oxazepine, and -thiazepine analogues were studied and shown to induce variable degrees of histone H3/H4 and tubulin acetylation in a cellular

from 2-bromobenzamides and 2-bromo(thio)phenols via twice copper-catalyzed couplings to afford dibenzothiazepines and dibenzoxazepinones has been developed. High levels of yield and chemoselectivity are achieved in a single-pot reaction by using an appropriate ligand. Moreover, this facile methodology allows rapid access to a variety of bioactive compounds and known psychotropic drug, which should
