Abstract

The invention relates to application of epiberberine in preparation of a urease inhibitor. In application, urease can becanavalia ensiformis urease and can be also helicobacter pylori. The urease inhibitor is granules, capsules or tablets. The urease inhibition effect of the epiberberine is remarkably better than that of recognized acetylhydroxamic acid.

Description

technical field [0001] The present invention relates to heterocyclic compounds, in particular to protoberberine compounds. Background technique [0002] Urease (Urease, EC 3.5.1.5, Ure), also known as urea amidohydrolase, is a nickel-containing ion (Ni 2+ ) metalloenzymes. Urease catalyzes the hydrolysis of urea to ammonia and thus plays an important role in nitrogen metabolism. However, if the activity of urease is too high, the catalytic hydrolysis of urea will be too fast, and a large amount of ammonia gas will be released, which will bring various hazards to agriculture, animal husbandry, the environment and even human health. In agriculture, urease catalyzes the hydrolysis of urea into ammonia too quickly, which will lead to the volatilization of ammonia and the excessive accumulation of nitrate ions and ammonium ions in the soil, thereby reducing the utilization rate of ammonia and polluting the atmosphere, water, soil and other environments; In animal husbandry, no...
