New Tetracyclic Derivatives of Imidazo[1,5-a][1,4]benzodiazepines and of Imidazo[1,5-a]-thieno[3,2-f][1,4]-diazepines
摘要:
The synthesis of new tetracyclic 1,4-diazepine derivatives is described. In these compounds, an additional five-membered heterocycle is fused on the known tricyclic ring systems imidazo[1,5-a][1,4]benzodiazepine and imidazo[1,5-a]thieno[3,2-f][1,4]diazepine. Many of these new compounds display a very high affinity to the benzodiazepine receptor in mammals.
The novel imidazodiazepine derivatives of the formula: ##STR1## wherein the substituents are as described in the specification, can be used for the control or prevention of epileptic seizures, anxiety, tension and excitation states, sleep disorders, schizophrenic symptoms, hepatic encephalopathy and senile dementia, as well as, in the partial or complete antagonization of undesired side-effects of substances acting on benzodiazepine receptors after over-dosage or after their use in intensive medicine and in anesthesia.
