چکیده
As part of an anti-psychotic drug discovery program, we report the crystal structure of the title compound, C(24)H(23)ClN(4)O. The mol-ecule has a tricyclic framework with a characteristic buckled V-shaped pyridobenzoxazepine unit, with the central seven-membered heterocycle in a boat configuration. The piperazine ring displays a chair conformation with the 2-phenyl-ethyl substituent assuming an equatorial orientation. There are two crystallographically independent, but virtually identical, mol-ecules in the asymmetric unit.

Effects of JL13, a pyridobenzoxazepine with potential atypical antipsychotic activity, in animal models for schizophrenia.
JL13 [5-(4-methylpiperazin-1-yl)-8-chloro-pyrido[2,3-b][1,5] benzoxazepine fumarate] is a substance with a close structural resemblance to clozapine. However, it is less sensitive to oxidation and may therefore have less hematological side effects. In the present study, JL13 was compared with clozapine and haloperidol in several animal models for schizophrenia. The paw test represents a screeni...

متن کاملSynthesis and antiproliferative activity in vitro of new 2-, 3- or 4-substituted pyrido[2',3':3,4]pyrazolo[1, 5-a]pyrimidines.
The synthesis of several new 2-, 3- or 4-substituted pyrido[2',3':3,4]pyrazolo[1,5-a]pyrimidines is described. The obtained compounds were tested for their antiproliferative activity in vitro. Two of them: 3-chloro-2-methylpyrido[2',3':3,4]pyrazolo[1,5-a] pyrimidin-4-one [X] and 2,3-cyclopentylpyrido [2',3':3,4] pyrazole[1,5-a]pyrimidin-4-one [XII] revealed weak cytotoxic activity against the c...
متن کاملDifferential effects of antipsychotic drugs on serotonin-1A receptor-mediated disruption of prepulse inhibition.
Serotonin-1A (5-HT(1A)) receptors have been implicated in the symptoms of schizophrenia. However, there is limited in vivo evidence for an interaction of antipsychotic drugs with 5-HT(1A) receptor-mediated behavioral effects. We therefore investigated in rats the action of several antipsychotic drugs on prepulse inhibition (PPI), a measure of sensorimotor gating that is deficient in schizophren...
