A dibenzothiazepine compound is suitably prepared by subjecting a 2-amino-2′-carboxy-diphenylsulfide compound to dehydration-condensation reaction in the presence of an acidic catalyst; the 2-amino-2′-carboxy-diphenylsulfide compound is suitably prepared by reducing a 2-nitro-2′-carboxy-diphenylsulfide compound in a lower aliphatic ester solvent; and the 2-nitro-2′-carboxy-diphenylsulfide compound is suitably prepared by reacting a nitrobenzene compound with a thiosalicylic acid compound in a mixture of a lower aliphatic alcohol and water.
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

The synthesis and pharmacological activity of basically substituted dibenzothiazepines are described. They possess interesting antihistamine and antiserotonine activity. By varying the substituents in the benzene nuclei, and by a suitable choice the basic side chains, the specifity and activity of some derivatives could be increased considerably, especially with the dibenzothiazepinones.

A process for preparing a dibenzothiazepine derivative such as dibenzo[b,f][1,4]thiazepin-11-one employable as a starting material for the preparation of 11-[4-(2-(2-hydroxyethoxy)ethyl)]-1-piperadinyldibenzothiazepine derivative which is known to be effective as an antipsychotic pharmaceutical, has the steps of reacting a nitrobenzene derivative with a thiosalicylic acid derivative, reducing the obtained 2-nitro-2′-carboxy-diphenylsulfide derivative, and subjecting the obtained 2-amino-2′-carboxy-diphenylsulfide derivative to dehydration-condensation reaction.
