Description
Technical Field
The invention belongs to the field of natural pharmaceutical chemistry, and relates to a preparation method of a monobenzyl isoquinoline alkaloid and application thereof in preventing or treating diseases such as pain, anxiety, depression and the like.
Background
The root and stem of Menispermaceae plant (Menispermum dauricum DC) is a traditional Chinese medicine, and is also called rhizoma Menispermi. Is used for treating tonsillitis, rheumatic arthritis, diarrhea, dysentery, gastroenteritis, cardiovascular diseases, thrombosis diseases, etc. The main component of the radix puerariae of bats is isoquinoline alkaloid and shows wide biological activity such as antiarrhythmic, antibacterial, anti-inflammatory, anti-tumor and the like. The isoquinoline alkaloid in radix Puerariae comprises multiple subclasses such as dibenzyl isoquinoline, benzyl isoquinoline, aporphine, protoberberine and morphinane. Wherein the content of dibenzyl isoquinoline alkaloid is high, and is about more than 85% of liposoluble alkaloid, represented by dauricine and dauricine Ge Sulin.
The technology of label-free cell integrated pharmacology (CLIP) based on an optical sensor is a novel phenotypic screening technology, and the principle of the technology is that when cells are subjected to external stimulus (such as drug small molecules are combined with receptors), many physiological actions generated by the cells bring about redistribution of cell internal mass, the change of the mass distribution is changed through a resonance waveguide grating (Resonant Waveguide Grating, RWG) biosensor, and an output signal is a change of reflection wavelength, so that a visualized dynamic mass reset (Dynamic mass redistribution, DMR) signal is formed, and the experimental operation process can be carried out on an Epic system. The CLIP technology has the characteristics of no labeling (no labeling of receptor and compound), no bias (phenotypic screening), high throughput, no damage, high spatial-temporal resolution (change of reflection wavelength in the whole measurement time range), and the like, and thus, the CLIP technology is widely applied in various fields including screening and discovery of natural product active molecules.
The radix puerariae hepiali is rich in isoquinoline alkaloid, and in view of the important pharmacological activity of isoquinoline alkaloid widely reported at present, the novel active isoquinoline alkaloid is found to be very significant from the radix puerariae hepiali by combining with the CLIP technology.
