cinazepam cinazepam cinazepam (bd-798, sold under brand name levana) is an atypical benzodiazepine derivative. it produces pronounced hypnotic, sedative, and anxiolytic effects with minimal myorelaxant side effects. in addition, unlike many other benzodiazepine and nonbenzodiazepine hypnotics such as diazepam, flunitrazepam, and zopiclone, cinazepam does not violate sleep architecture, and the continuity of slow-wave sleep and rem sleep are proportionally increased. as such, cinazepam produces a sleep state close to physiological, and for that reason, may be advantageous compared to other, related drugs in the treatment of insomnia and other sleep disorders. cinazepamclinical dataatc codenoneidentifiers iupac name 4--4-oxobutanoic acid cas number172986-25-3pubchem cid629281chemspider546502uniiu4ss7ufxc7chemical and physical dataformulac19h14brcln2o5molar mass465.68 g·mol−13d model (jsmol)interactive image smiles c1ccc(c(c1)c2=nc(c(=o)nc3c2cc(cc3)br)oc(=o)ccc(=o)o)cl inchi inchi=1s/c19h14brcln2o5/c20-10-5-6-14-12(9-10)17(11-3-1-2-4-13(11)21)23-19(18(27)22-14)28-16(26)8-7-15(24)25/h1-6,9,19h,7-8h2,(h,22,27)(h,24,25)key:nqtrbzxdwmdxaq-uhfffaoysa-n cinazepam has an order of magnitude lower affinity for the benzodiazepine receptor of the gabaa complex relative to other well-known hypnotic benzodiazepines such as nitrazepam and phenazepam. moreover, in mice, it is rapidly metabolized, with only 5% of the base compound remaining within 30 minutes of administration. as such, cinazepam is considered to be a benzodiazepine prodrug; specifically, to 3-hydroxyphenazepam, as the main active metabolite.
