Abstract

The invention discloses application of a curcumin-zinc compound in preparing bacteriostatic analgesics. The invention discloses the curcumin-zinc compound has good bacteriostatic abirritation, can be used for curing common diseases of retinopathy, skin ulcer and the like caused by bacterial infection, pains and complications of diabetes and has effective treatment and wide application in curing various senile diseases. The curcumin-zinc compound can be used for preparing drugs and various health care products and solves the problems of single indication of the drugs and undesirable curative effect in curing the senile diseases at present. The curcumin-zinc compound has simple preparation method and wide application prospect.

Description

technical field [0001] The invention relates to the field of pharmaceutical compositions, in particular to the medical and health care applications of curcumin-zinc compounds in antibacterial and analgesic aspects. Background technique [0002] Total curcumin [including curcumin, demethoxycurcumin, bisdemethoxycurcumin], the main active ingredient is curcumin, which has a good free radical scavenging , anti-oxidation, anti-mutation, anti-aging, anti-radiation, anti-virus, anti-cancer, anti-cancer, lowering blood fat and cholesterol, anti-atherosclerosis, treatment of depression and other health care and pharmacological effects. [0003] Curcumin and copper ions can form metal complexes in ratios of 1:1 and 1:2. Cu(II)-curcumin metal complex has a stronger ability than curcumin to scavenge free radicals induced by γ-rays and cadmium and simulate SOD antioxidant capacity. Curcumin-magnesium complex, as a neuroprotective agent, has a better effect on scavenging free radicals ...
