Аннотация
In this work, a series of novel heterocyclic 2-phenylacetate derivatives were designed and synthesized as water-soluble and rapid recovery hypnotic agents. After introducing heterocyclic ring to the amide group of propanidid, the obtained propanidid derivatives showed greatly improved hydrophilicity and good anesthetic activity. In three animal experiments (mice, rats, and rabbits), compounds 13-15 showed potent hypnotic potency (HD50 = 7.6, 6.5, 7.4 mg/kg in rabbits, respectively) and higher therapeutic indexes (TI = 17.3, 16.6, 15.2 in rabbits, respectively) than propanidid (TI = 14.7 in rabbits) or propofol (TI = 5.4 in rabbits). Moreover, the recovery time of compounds 13-15 (time to walk, 96.6, 79.6, 81.4 s in rabbits, respectively) were shorter than that of propanidid (124.5 s in rabbits) or propofol (425.3 s in rabbits). The experimental results suggested the potential of compounds 13-15 as water-soluble anesthetics with rapid recovery profile.
