Abstract
4-Hydroxybenzyl alcohol (HBA), one of the characteristic active components of Gastrodia elata, exhibits obvious effects on the human central nervous system. In order to acquire compounds with superior bioactivity, 10 derivatives of HBA were synthesized from HBA and carboxylic acids. The sedative effects of the 10 HBA derivatives were evaluated using a spontaneous locomotor activity test (SLT) in mice, and their hypnotic effects were determined to be synergistic with pentobarbital-induced sleep. The results showed that 4-hydroxybenzyl alcohol 3-furancarboxylic acid diester (2FHBA, 10 mg kg-1) exhibited the strongest sedative-hypnotic activity among HBA and its derivatives, and 2FHBA could reverse the insomnia caused by p-chlorophenylalanine (pCPA), flumazenil (FLU) and thiosemicarbazide (TSC). Meanwhile, 2FHBA and 5-hydroxytryptophan (5-HTP) showed a synergistic effect. The results suggested that 2FHBA might be a potential agent against insomnia, which might be mediated by the serotonergic and GABAergic systems.
TL;DR
2FHBA might be a potential agent against insomnia, which might be mediated by the serotonergic and GABAergic systems, and 2FHBA could reverse the insomnia caused by p-chlorophenylalanine, flumazenil (FLU) and thiosemicarbazide (TSC).
