Studies on annulated 1,4-benzothiazines and 1,5-benzothiazepines. IX. Imidazo [2,1-d][1,5] benzothiazepines: synthesis and in vitro benzodiazepine receptor affinity
摘要:
The synthesis of three series of 1- and 2-substituted imidazo[2,1-d][1,5]benzothiazepines is accomplished starting from 1,5-benzothiazepin-4-ones. All the synthesized compounds were evaluated for their affinity for the benzodiazepine receptor, testing their ability to displace [H-3]Flunitrazepam from bovine brain membrane protein. A few of the tested compounds showed good affinity, in particular compound 9a (K-i = 43.00 nM). The GABA-ratio of the active compounds suggests an antagonist or partial agonist activity. The data obtained allow us to draw some comments on the structure-activity relationships.

2,3‐dihydro‐1,5‐benzothiazepinones, by an organocatalyzed sulfa‐Michael reaction of readily available α,β‐unsaturated N‐acyl pyrazoles with 2‐aminothiophenols followed by silica‐gel‐catalyzed lactamization, has been developed. The method proceeds under mild conditions at room temperature and it requires only 1 mol % catalyst loading, to give 2‐aryl/alkyl‐substituted 1,5‐benzothiazepines in generally

A practical and efficient method for the preparation of 1,5-benzothiazepinone derivatives in good yields has been developed using tetrabutylammonium fluoride (TBAF) as a catalyst. This study not only expands the previous work on the substrate scope and also provides more understanding of the chemistry of such drug scaffolds.

amenable to generating both racemic and enantioenriched benzothiazepine-based derivatives. The obtained compounds showed potent HDAC inhibitory activity, especially those containing the sulphone moiety, endowed with IC50 in the nanomolar range. In addition, in vitro outcomes of our synthesized compounds demonstrated a cytotoxic effect on U937 and HCT116 cell lines and an arrest in the G2/M phase (13 ≤ IC50 ≤ 18 µM)
