Embodiment Construction

[0015] A method for preparing adenyl succinic acid or salt, using the Escherichia coli expression system pET-28-a vector to express PhAdSS with the sequence of MGSSHHHHHHSSGLVPRGSH at the N-terminal, and using the recombinant protein as a catalyst to catalyze inosinic acid IMP , L-aspartic acid and guanosine triphosphate GTP to synthesize S-AMP and GDP. After the synthesis reaction, use silica gel thin-layer chromatography to analyze the components in the product, and perform silica gel column chromatography separation according to the results of silica gel thin-layer chromatography Purify S-AMP, and then use recrystallization method to further improve the purity of product S-AMP.

[0016] The specific preparation method is:

[0017] (1) Construction of expression plasmid: In the previous study, we used the pET-19-b prokaryotic expression vector to express and purify PhAdSS. According to the reported expression and purification conditions of PhAdSS, 5 mg of PhAdSS with a purit...

Abstract

The invention belongs to the technical field of scale production of candidate medicines for treating glucose-lipid metabolism disorder diseases. In order to solve the problems that existing S-AMP is difficultly produced, the price of the S-AMP is expensive, and raw material sources of the druggability of the S-AMP is difficulty ensured, the invention provides a preparation method of adenylosuccinic acid or adenylosuccinate. PhAdSS of which the N terminal is provided with an His-tag sequence is expressed by utilizing a pET-28-a carrier; with the PhAdSS as a catalyst, inosinic acid IMP, L-aspartic acid and guanosine triphosphate (GTP) are catalyzed and subjected to reaction to synthesize S-AMP; after the reaction is carried out, components in a product are analyzed by adopting silica gel thin-layer chromatography, and separation and purification on the S-AMP are carried out by adopting silica gel coluumn chromatography. The content of the s-AMP in a synthetic product is 61 percent, and arecycling ratio is about 20 percent. A preparation process is simple, the cost is low, and a basis is laid for building an industrialized S-AMP synthetic process; monopoly sale on S-AMP by foreign sellers is expected to be broken through, and the S-AMP druggability research cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of large-scale production of candidate drugs for the treatment of disorders of glucose and lipid metabolism, and in particular relates to a preparation method of adenylosuccinic acid or a salt thereof and an application thereof. Using enzymes from deep-sea archaea to catalyze the synthesis of a natural adenosine compound: adenylyl succinic acid (salt), a small-scale laboratory preparation method was established. This compound has the function of promoting insulin secretion, and can be used as a candidate drug for improving glucose and lipid metabolism disorders to carry out druggability research. Background technique [0002] Adenylosuccinic acid (Adenylosuccinate), referred to as S-AMP] is a natural adenosine compound that promotes insulin secretion and restores the normal function of islet cells in patients with type II diabetes [1]. In previous studies, we found that S-AMP is an agonist of AMPK, and its ...
