Abstract

The invention provides a high-throughput screening method for screening a vasoactive intestinal peptide I type receptor inhibitor; in experiments, with use of coupling of a vasoactive intestinal peptide type I receptor and a Gs protein, AC is activated, the cAMP content is increased, a product with fluorescence can be produced, the role of the vasoactive intestinal peptide type I receptor is judged by the fluorescence intensity, and thus whether the obtained compound has an inhibitory effect of the vasoactive intestinal peptide type 1 receptor is obtained. The method comprises the following steps: 1) establishment and optimization of a screening model of the vasoactive intestinal peptide I type receptor inhibitor: determining the most suitable concentration for a reaction of VIP and vasoactive intestinal peptide I type receptor cells; and 2) model reliability verification with positive drug: verifying that a positive drug IC50 is in accordance with that of a reference. The method has the advantages that the method is simple and fast, sensitivity of the fluorescence detection value is high, detection accuracy is increased, the result is stable and reliable, and the reappearance is good.

Description

technical field [0001] The invention belongs to the field of pharmacology, and uses fluorescence detection technology to construct a high-throughput screening model for vasoactive intestinal peptide type I receptor inhibitors, which is used for high-throughput screening of the inhibitory activity of test samples on vasoactive intestinal peptide type I receptors. volume detection. technical background [0002] Vasoactive intestinal peptide type I receptor is a co-receptor of neuropeptide and vasoactive intestinal peptide, mediating a variety of important biological functions, such as vasoactive intestinal peptide type I receptor mediating neuropeptide and vasoactive intestinal peptide inhibition Biological functions of appetite and anti-inflammation. Vasoactive intestinal peptide type I receptors are abundantly expressed in the brain and T cells and can regulate neuronal differentiation and T cell activation. Vasoactive intestinal peptide type I receptor, as one of the subt...
