Usage

Uses

8-Chlorodibenzo[b,f]thiepin-10(11H)-one is an intermediate in the synthesis of Zotepine-d6, which is the labeled analogue of Zotepine (Z700900), an atypical antipsychotic drug used for the treatment of acute and chronic schizophrenia, and acute bipolar mania. It acts as antagonist at dopamine and serotonin receptors. It has a high affinity for the D1 and D2 receptors.

Exploring the neuroleptic substituent in octoclothepin: Potential ligands for positron emission tomography with subnanomolar affinity for α1-adrenoceptors

A series of 1-(10,11-dihydrodibenzo[b,f]thiepin-10-yl)-4-methylpiperazine analogues substituted in the 8-position of the 10,11-dihydrodibenzo[b,f]thiepine scaffold with aryl, heteroaryl, amine, and amide substituents are described. The compounds were designed using the previously reported Liljefors- B?ges? pharmacophore model for dopamine D2 and α1-adrenoceptor antagonists, with the aim of obtaining selective α1-adrenoceptor antagonists suitable for development as radioligands for imaging of central α1-adrenoceptors by positron emission tomography. Sixteen aryl and heteroaryl substituted octoclothepin analogues were prepared by a convergent synthesis via coupling of 1-methyl-4-(8-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-10, 11-dihydrodibenzo[b,f]thiepin-10-yl)piperazine with aryl and heteroaryl halides under palladium catalysis. The most selective compound obtained, (S)-N-((11-(4-methylpiperazin-1-yl)-10,11-dihydrodibenzo[b,f]thiepin-2-yl) methyl)isobutyramide (S)-35, showed a similar subnanomolar affinity compared to α1a, α1b, and α1d- adrenoceptors and a selectivity ratio of 20, 440, and 20 with respect to D 2, 5-HT2C, and H1 receptors, respectively.
