- Clozapine intermediate as well as synthesis method and application thereof (by machine translation)
-
The invention discloses a clozapine intermediate and a synthesis method and application thereof, and belongs to the technical field of drug synthesis. The synthesis method comprises 1) synthesis of 2 - [(2 - amino -4 - chlorophenyl) amino] benzoic acid, 2) 8 - chlorine -5, 10 - dihydro - 111111H-dibenzo [b, e] [1, 4]-diazepine -11 - ketone. The synthesis method of the clozapine intermediate is simple in preparation process, recyclable in solvent, easy to operate and control, good in color, good in quality, high in purity and high in yield, can be directly used for production and use, and has good practicability.

- Synthesis and pharmacological evaluation of 11-(1,6-dimethyl-1,2,3,6-tetrahydropyridin-4-yl)-5H-dibenzo[b,e][1,4]diazepines with clozapine-like receptor occupancy at dopamine D1/D2 receptor

Clozapine-like compound without agranulocytosis risk is need to cure the treatment resistant schizophrenia (TRS). We discovered (S)-3 as Clozapine-like dopamine D2/D1 receptor selectivity and improved reactive metabolites formation profile by the modification of piperazine moiety in Clozapine. The optimization of (S)-3 gave compound 5 to be best compound (approximately 10-fold stronger affinity for D2/D1 receptor and similar D2/D1 selectivity ratio with Clozapine). Clozapine-like D2/D1 receptor occupancy profile was proved by in vivo evaluation. In addition, the reactive metabolites derived agranulocytosis risk of compound 5 was considered to be lower than Clozapine. The pharmacology detail of compound 5 is being investigated to develop it for TRS treatment.

- Design, synthesis and anticancer activity evaluation of diazepinomicin derivatives
-
A series of diazepinomicin derivatives were synthesized and evaluated in vitro for their growth inhibitory activity against the human carcinoma cell lines. The results indicated the anticancer selectivity of this kind of compounds. Based on the results, preliminary structure-activity relationships were discussed.

- Synthesis and preliminary pharmacological evaluation of 4′-arylmethyl analogues of clozapine. I - The effect of aromatic substituents
-
As part of a research program to develop compounds with mixed dopamine D4 and serotonin 5-HT2A antagonist activity with potential for the treatment of schizophrenia, we report a family of compounds based on structural modification of the atypical antipsychotic, clozapine (2). The chemical synthesis, structural characterization and pharmacological evaluation of a series 4′-arylmethyl analogues of clozapine are described. Preliminary receptor binding data are presented, examining primarily the electronic and positional effects of substituents on the introduced arylmethyl group, and secondarily the nature of the aryl ring.
