Article abstract of DOI:10.1021/jm00252a011

A series of 2,3 dihydro 1H thieno[2,3 e][1,4]diazepines was synthesized and evaluated for CNS activity. A new antianxiety screen for benzodiazepine like drugs was used along with the standard anticonvulsant test. Structure activity relationships are discussed. One compound, 1,3,6,7,8,9 hexahydro 5 phenyl 2H [1]benzothieno[2,3 e][1,4]diazepin 2 one monosulfate (CI 718), is undergoing clinical studies in man.
