Abstract
The invention provides a polaprezinc compound. Polaprezinc compound is an L-carnosine complex of zinc, and the chemical name is poly 2-(S)-[mu-[N <alpha> (3-aminoproionyl)-L-histidine (2-)-N<1>,N<2>,O:N <tau>]-zinc). L-carnosine is a dipeptide that consists of beta-phenylalanine and L-histidine, and is an anti-oxidant that can promote wound healing. The polaprezinc compound of the present invention can be rapidly absorbed in vivo and eliminated after single or multi-time drug-feeding; multi-time drug-feeding has no accumulation phenomenon. Within test dosage, the subject can bear better and no light or severe adverse events happen during the whole test process, which means the drug is safe and has good human body tolerance. The improvement rate of chief complaint ulcer is 94.44%.
Description
Technical field
The invention belongs to the pharmaceutical technology field, relate to particularly a kind of zinc L-carnosine compound.
Background technology
Peptide ulceration is 4.57% at China's sickness rate, and mainly take person between twenty and fifty as main, serious threat China labor force population affects China's Economic development.
Peptide ulceration mainly because of smoking, drink, nervous, medicine irritation (such as NAIDS) causes, its pathogenesis focuses on unbalance between the two of invasion and attack factor and defending factors at present, and the difference of individual neuroendocrine response and hereditary predisposition.Antiulcer drug mainly is divided into anti-invasion factor medicine and promotes the defense factor medicine; the anti-invasion factor comprises antacid, presses down sour medicine such as m receptor blocking agent, G receptor antagonist, histamine H2-receptor blocking agent and Proton pump inhibitor and antipepsin medicine, promotes defense factor class cartridge bag to draw together and promotes mucus generation medicine, mucosa protective agent and improve mucous membrane blood circulation medicine.
Zinc L-carnosine is the N-BETA-Alanyl-L-histidine complex compound of zinc, its chemistry poly-2-(S) by name-[μ-[N
α(3-aminopropan acyl group)-L-Histidine (2-)-N
