Description

A kind of pharmaceutical composition of the suppression drug-resistant staphylococcus aureus containing resveratrol
Technical field
The invention belongs to pharmaceutical field, is related to the pharmaceutical composition for suppressing drug-resistant staphylococcus aureus, and in particular to compound 3,4 ', 5- trihydroxy talan (resveratrol Resveratrol) and its preparing the anti-methicillin-resistant staphylococcus of resistance to fluoroquinolones Purposes in staphylococcus medicine.
Background technology
Prior art discloses methicillin-resistant Staphylococcus aureus (Methicillin-Resistant Staphylococcus aureus, MRSA) it is one of most common disease carrying germ in hospital, except superficial skin infection, it is also The deep infection of inside of human body can be caused.Clinical practice shows have to medicines such as all lactam antibioticses such as penicillin There is the MRSA of drug resistance, drug resistance is also generated to antibiotic such as macrolide, fluorine quinolione, tetracyclines, this causes its sense Dye becomes more difficult to treat.At present, the antibiotic available for treatment MRSA only has vancomycin, Unfortunately, completely Anti-vancocin MRSA bacterial strains had occurred for 2002 already in the U.S..China is widely used due to antibiotic in recent years, or even excessively With for particularly vancomycin after multiple hospitals become Conventional antibiotic class medication, this situation becomes further severe.Except Take measures to slow down the speed that drug resistance MRSA increases by limiting abuse of antibiotics, while research and develop new anti-multidrug resistance MRSA Medicine is particularly important, it will be to when existing antibacterials can not work, the large-scale outbreak of bacterium plays prevention Effect.
Studies have shown that bacterium can produce drug resistance (Drug Resistance) through a variety of ways, and wherein bacterium is to medicine Outer pump (efflux) drug resistance is important mechanism of drug resistance caused by producing outer row's effect.According to the report of the World Health Organization Accuse, the bacterial infection with multidrug resistance efflux pump has accounted for the 60% of nosocomial infection.
Studies have reported that methicillin-resistant staphylococcus aureus has a variety of resistance mechanisms, except being with chromosome The drug resistant gene (mecA) of 40Kb is produced by encoding methicillin adaptor protein (Penicilin Bindin Protein, PBP) Outside life is to the drug resistance of beta-lactam antibiotic, also to macrolides (macrolide), fluoroquinolones (fluoroqiunolones), tetracycline and quaternary ammonium salt produce resistance to by MsrA, NorA, TekA, the outer chlGs of QacA respectively Medicine mechanism, bacterial cell pumps out the most antibiotic generally used extracellularly in these resistance mechanisms, makes intracellular Antibiotic concentration reduce and antibacterial action can not be played.The gene of resistance to fluoroquinolones NorA (42kDa) is present in S. aureus L-forms In the Sma I D fragments of S.aureus chromosomes, at first it is only regarded as fluoroquinolones drug resistant gene, shows later pair The drug resistance of Multiple Classes of Antibiotics type.NorA genes over-express product NorA albumen in S.aureus and are located on cytoplasma membrane It is sub (transporter) as main transhipment, using the multi-medicament including fluoroquinolones as matrix, or it is sub with other transhipments Synergistic effect, pumps out cell by drug molecule, produces the drug resistance of bacterium.Therefore, the multiple medicine with NorA drug resistant genes is chosen Drug-resistant staphylococcus aureus are an important channels for finding new drug resistance bacteria inhibitor in the industry as target.
It is reported that resveratrol has antitumor, anti-inflammatory, immunological regulation, antibacterial, antiviral, anti-aging and estrogen-like The multiple pharmacological effects such as activity, wherein in terms of antimicrobial agent, have been reported resveratrol joint Ciprofloxacin to resistance to methoxy west The gold-coloured staphylococci MTCC 902 of woods has good inhibitory action, and FICI values reach 0.14, and (FICI values < 0.5 is to have association Same-action);And resveratrol joint cefotaxime equally has the gold-coloured staphylococci MTCC 902 for cooperateing with anti-methicillin-resistant Effect, FICI values reach 0.31;Resveratrol combines fluorine quinolone compounds Ciprofloxacin to bacillus subtilis MTCC 2756 (FICI values are 0.13) and Escherichia coli MTCC 2622 (FICI values are 0.12) and pseudomonas aeruginosa MTCC 2642 (FICI values are 0.25) equally has coordinate repression;Still some researches show that resveratrol joint Quercetin can cooperate with anti- Drug-resistant staphylococcus aureus SA1056 (FICI values are 0.375);, resveratrol may interfere with quorum sensing (quorum sensing, QS, again Claim threshold value sensitive, be that bacterium carries out the exchange of intracellular or cell-tocell according to population density size, coordinate group behavior and adjust Control gene expression a kind of mode) and surface protein and capsular polysaccharide synthesis;The prior art discloses resveratrol can Can participate in the auxiliary treatment of MRSA infection by acting on biomembrane.
So far, there is not yet on resveratrol to the antibacterial action with the MRSA bacterial strains that gene is pumped outside NorA Report.Based on this, present inventor intends providing a kind of drug regimen of the suppression drug-resistant staphylococcus aureus containing resveratrol Thing, wherein resveratrol are combined with Norfloxacin, will be had to fluorine-resistant promise quinoline ketone antibiotic Methicillin-resistant Staphylococcus aureus good Coordinate repression.
