  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.

  A Simple and Efficient Method for Synthesis of Benzothiazepine Derivatives

  摘要：

  A series of 1,5-benzothiazepines were synthesized using disulfides and alpha,beta-unsaturated carbonyl or nitrite compounds as reaction substrates. After reductive cleavage of the S-S bond of disulfides, the resulting thiols were reacted with alpha,beta-unsaturated carbonyl or nitrite compounds to generated seven-membered heterocyclic compounds. In the presence of ammonium thioglycolate, the Michael reaction occurred between disulfides (1) and 4-methyl-3-penten-2-one to give 2,2,4-trymethyl-3H-1,5-benzothiazepine derivatives in good yields. When ethyl acrylate or acrylonitrile was used as the Michael acceptor, 90-99% of (2-amino-phenylsulfanyl)propionitriles (3) and/or 92-99% of (2-amino-phenylsulfanyl)propionic acid ethyl esters (4) were produced. Subsequently, the 1,5-benzothiazepine compounds 5 and 6 were obtained due to the cyclization reaction.

  An improved one-pot synthesis of 1,5-benzothiazepinone derivatives is described. 2-Aminobenzenethiols are conveniently converted into 2,3-dihydro-1,5-benzothiazepin-4(5H)-ones by reaction with ß-propiol-actone or ß-butyrolactone in anhydrous pyridine followed by treatment with acetic anhydride. Some substituent effects are noted.

  Some derivatives of indolo[2,3-b]-1,5-benzothiazepine, a novel heterocyclic ring system, and of its 5,6-dihydroderivative have been obtained by Fischer indolization of corresponding phenylhydrazones. All the tetracyclic compounds were studied for their antimicrobial and cytostatic activities and several of them showed good activity against Gram-positive bacteria and Cryptococci.
