RESUMO

Insomnia is extremely common and is a risk factor for a variety of physical and psychological disorders in addition to contributing to the reduced quality of life of patients and the burden of healthcare costs. Although cognitive behavioral therapy is the first-line treatment for insomnia, its difficulty of access and high cost have hindered its application. Therefore, pharmacotherapy remains the common treatment choice for patients and clinicians. Existing chemical drugs including benzodiazepine receptor agonists, dual orexin receptor antagonists, melatonin and its receptor agonists, histamine antagonists, antidepressants, and antipsychotics are able to induce and/or maintain sleep and have good therapeutic effects on acute insomnia, but their efficacy on chronic insomnia is indefinite. Furthermore, they have several side effects and affect sleep structure and physiological function. Under the guiding principle of holistic view and treatment based on syndrome differentiation, traditional Chinese medicine(TCM) has shown a good effect in clinical practice, but with little high-grade clinical evidence. The mechanism, dose, half-life period, adjustment of sleep structure, and side effects of hypnotic drugs are key factors to be considered for clinical use. This paper analyzed and summarized the drugs for insomnia from the above aspects, and is expected to provide references for the application and development of sedative and hypnotic drugs.

RESUMO

Chemical investigation of the culture extract of an endophyte Xylaria curta YSJ-5 from Alpinia zerumbet (Pers.) Burtt. et Smith resulted in the isolation of eight previously undescribed compounds including five eremophilane sesquiterpenes xylarcurenes A-E, one norsesquiterpene xylarcurene F, and two α-pyrone derivatives xylarpyrones A-B together with eight known related derivatives. Their chemical structures were extensively established based on the 1D- and 2D-NMR spectroscopic analysis, modified Mosher's method, electronic circular dichroism calculations, single-crystal X-ray diffraction experiments, and the comparison with previous literature data. All these compounds were tested for in vitro cytotoxic, anti-inflammatory, α-glucosidase inhibitory, and antibacterial activities. As a result, 6-pentyl-4-methoxy-pyran-2-one was disclosed to display significant antibacterial activity against Staphylococcus aureus and methicillin-resistant S. aureus with minimal inhibitory concentration value of 6.3 µg/mL.
