Studies on annelated 1,4-benzothiazines and 1,5-benzothiazepines. VII. Synthesis and inhibition of benzodiazepine receptor binding of some 4,5-dihydro-tetrazolo[5,1-d]-1,5-benzothiazepines and 5-phenyl-s-triazolo[3,4-d]-1,5-benzothiazepines.
The 4,5-dihydro-tetrazolo[5,1-d]-1,5-benzothiazepines 3a-k and the 5-phenyl-s-triazolo[3,4-d]-1,5-benzothiazepines 6a-f and 11a-c have been prepared and tested for their ability to displace [3H] flunitrazepam binding from bovine brain membranes. Some of the triazoloderivatives showed moderate binding affinity for the benzodiazepine receptor.
