Prepare new derivatives 5-(3-Fluoro-biphenyl-2-yl)-7-nitro-1,3-dihydro-benzo[e] [1,4]diazepin-2-ol (88)and 5-Nitro-2’-(7-nitro-2-oxo-2,3-dihydro-1H-benzo[e][1,4]diazepin-5-yl)-biphenyl-3-carboxylic acid (89)compound from clonazepam and identified by spectrum of 13C-NMR and showed spectrum 1H-NMR . Clonazepam has massive adverse effect on prostate,lung,liver,kidney and spleen 3-new derivatives 5-(3-Fluoro-biphenyl-2-yl)-7-nitro-1,3-dihydro-benzo[e] [1,4]diazepin-2-ol (88) has limited effect and there is no clear changes in most organs studies.4-5-Nitro-2’-(7-nitro-2-oxo-2,3-dihydro-1Hbenzo[e][1,4]diazepin-5-yl)-biphenyl-3-carboxylic acid (89)compound has significant adverse effect but still less potent than clonazepam.
OBJECTIVE
To characterization and synthesis of new drugs related to clonazepam as well as to overcome massive adverse effect of clonazepam and increase the potency and half live of drugs.
