The numerous positive results and broad avenues of research on Murrayanine, a heterocyclic compound (carbazole) obtained from Indian curry plant Murraya koenigii L. (Rutaceae) have attracted us in developing semi-synthetic products with better pharmacodynamics and pharmacokinetic profiles. From our research group, various therapeutically active murrayanine based hybrid compounds have been developed where the extracted murrayanine was cyclized to various five/six-membered heterocyclic components such as isoxazole, thiazole, phthalimide, pyrazole, pyrimidine, hydantoin, Schiff ’s bases, etc. which demonstrated multifarious pharmacological activities like anti-oxidant, anti-convulsant, anti-bacterial, anti-fungal, anti-cancer, anti-diabetic, and anti-inflammatory. The present research aimed at developing several seven-membered heterocycle 3H-benzo[b][1,4]diazepine derivatives from Murrayanine-Chalcone, a hybrid compound previously reported by our research group by cyclization reaction and exploring the anti-anxiety or hypnotic effects of the fabricated molecule by evaluating locomotor inhibitory activity in Swiss albino rat. The study revealed the perspective to fabricate semi-synthetic heterocycles from murrayanine, which is a natural product and thus render desired safety and efficacy. The sophisticated analytical and spectroscopic tools revealed that the compounds were found to be in close agreement with that of the proposed structure. The influence of position, number, and the type of substituent were comprehensively studied where the lipophilic substituent containing scaffold (3h) presented the highest locomotor inhibition and therefore will translate antianxiety effect therapeutically. The study will open new avenues of research and will surely motivate the researchers in the rational development of safe and efficacious molecules in future from natural origin.
