Abstract

6-p-Methoxyphenylpyrrolo[2,1-d][1,5]benzothiazepin-7(6H)-one (IV), cis-7-acetoxy-6,7-dihydro-6-p-methoxyphenylpyrrolo[2,1-d] [1,5]benzothiazepine (V) and some significant 7-acyloxy-6-p-methoxyphenylpyrrolo[2,1-d][1,5]benzothiazepines (VI a-g) were synthesized and tested in vitro for inhibition of the specific binding of 3H-Flunitrazepam, 3H-PK 11195, 3H-Muscimol and 3H-(-)Baclofen to central and peripheral benzodiazepine, GABA-A and GABA-B receptors, respectively. The compounds (IV), VI a) and (VI c) were active on the peripheral benzodiazepine receptor; in particular (VI a) and (VI c) were very active. The compound (VI g) showed an affinity, even though scanty, for the central benzodiazepine receptor.
