(3). visible by above-mentioned experiment; Nuezhenoside, hyperin compositions can be through suppressing influenza virus surface neuraminidase; And then suppress that influenza virus gets into the cell the inside, the influenza virus that suppresses to have got into the cell the inside duplicates, breeds; Thereby reduced infection, the growth of influenza virus pair cell, and prevention and treatment influenza and complication thereof.
Medical science and study of pharmacy personnel can't not do the inhibition influenza infection, duplicate in advance, or under the prerequisite of the experiment of inhibition neuraminidase, learn that in advance nuezhenoside, hyperin compositions have prevention and treat the good result that the influenza virus sexuality is emitted.
Experimental data 2: nuezhenoside, hyperin compositions infect the inhibitory action of Embryo Gallus domesticus to influenza virus
Get nuezhenoside, hyperin compositions that embodiment 6 method for preparinies are obtained, use influenza virus A-prime Mus lung adapted strain (FM1) and (H1N1) identify that nuezhenoside, hyperin compositions suppress the ability that the FM1 influenza virus is duplicated and suppresses in Embryo Gallus domesticus.(1). FM1 influenza virus liquid is inoculated in 10d no-special pathogen in age chick embryo allantois intracavity, and every embryo 0.2ml is hatched 72h for 37 ℃, observes and calculate half Embryo Gallus domesticus infective dose (EID50).(2). nuezhenoside, hyperin compositions adopt the toxic action of Embryo Gallus domesticus; Physiological saline solution is done to be inoculated in 10d no-special pathogen in age chick embryo allantois intracavity behind the serial dilution to nuezhenoside, hyperin compositions; Every embryo 0.2ml, each concentration is inoculated 6 embryos, hatches for 37 ℃; Observe Embryo Gallus domesticus growth promoter situation, can survive the Cmax of 96h as the TD of medicine with Embryo Gallus domesticus.(3). nuezhenoside, the hyperin compositions inhibitory action to influenza virus in Embryo Gallus domesticus adopts; 0.1ml influenza virus liquid and different dilution nuezhenoside, hyperin compositions mix; 37 ℃ of effect 2h; Be inoculated in 10d no-special pathogen in age chick embryo allantoic cavity, every winding kind 6 embryos are hatched 72h for 37 ℃.The virus attack amount is 50EID50, establishes virus control, physiological saline solution normal control simultaneously, calculates nuezhenoside, the hyperin compositions median effective dose (ED50) to viral inhibition.
(1) the .FM1 influenza virus is calculated through the Reed-Muench method the virulence of Embryo Gallus domesticus, and its EID50 is 10
-5.07(2). after nuezhenoside, hyperin compositions are inoculated in Embryo Gallus domesticus, its growth promoter and normal control group basically identical.The 96h Embryo Gallus domesticus is all survived.Embryo Gallus domesticus gives nuezhenoside, hyperin compositions stock solution is not seen chicken embryo death, so can think that TD0 is 4.6g/L.(3). nuezhenoside, the hyperin compositions inhibitory action to influenza virus in Embryo Gallus domesticus is seen table 3.
Table 3. nuezhenoside, hyperin compositions infect the inhibitory action of Embryo Gallus domesticus to influenza virus
Compare with the virus control group:
*P<0.05
Can know that by table 3 nuezhenoside, hyperin compositions have significant inhibitory effect (P<0.05), ED at 0.2875~2.3g/L to influenza virus
50Be 0.38g ± 0.16mg/ml, TI is 21.84 ± 3.91.
Experimental data 3: nuezhenoside, hyperin compositions influence the FM1 influenza virus
Get nuezhenoside, hyperin compositions that embodiment 6 method for preparinies are obtained, use influenza virus A-prime Mus lung adapted strain (FM1) and (H1N1) identify that nuezhenoside, hyperin compositions suppress the ability of FM1 influenza virus virulence.(1) .FM1 adopts cell ID 50, median infective dose (TCID50) micromethod to the toxicity test of Testis et Pentis Canis passage cell (MDCK).(2). nuezhenoside, hyperin compositions adopt the DMEM of serum-free that nuezhenoside, hyperin compositions are done to be inoculated in the mdck cell hole that forms monolayer behind the serial dilution to the toxicity test of mdck cell; Every hole 100 μ l; Each dilution factor repeats 4 holes, establishes the normal cell contrast simultaneously.Culture plate is put 37 ℃, 5%CO
2Cultivate in the incubator, observation of cell pathological changes every day (CPE) is observed 3d continuously, with " +~++ ++ " the record result, press the Reed-Muench method and calculate medicine median toxic concentration (TD50) and maximal non-toxic concentration (TD0).(3). nuezhenoside, hyperin compositions suppress the effect of FM1 influenza virus and measure: mdck cell 5 * 10
5/ ml, every hole 100 μ l, in 96 orifice plates, 37 ℃, the interior cultivation of 5%CO2 incubator are inhaled and remove culture fluid in the hole next day, add 100TCID50 influenza virus liquid, every hole 100 μ l, supernatant is removed in suction behind 37 ℃ of absorption 1h.Wash 2 times with phosphate buffer (PBS); TD0 with medicine is the 1st hole, and the DMEM liquid of reuse serum-free is made serial dilution to nuezhenoside, hyperin compositions, adds respectively in the cell of above-mentioned infective virus; Establish virus control and normal control group simultaneously, 37 ℃, 5%CO
2Cultivate in the incubator, observe the mdck cell characteristics of lesion that influenza virus produces every day, i.e. cell monolayer degeneration becomes circle etc., and 3d calculates 50% of medicine and suppresses pathological changes concentration (IC50) and therapeutic index (TI) continuously.The calculating of TI: TI=TD50/IC50, the TI value is big more, shows that the safety range of medicine is big more.With Kruskal-Walis and Mann-Whitney method of inspection comparative test group and the cytopathic difference of virus control group; Drug dose and suppression ratio that virus infected cell is avoided cytopathy (CPE) takes place are carried out correlation analysis, judge whether amount validity response relation.
(1) the .FM1 influenza virus is calculated through the Reed-Muench method the virulence of mdck cell, and its TCID50 is 10
-4.81(2). the TD0 of nuezhenoside, hyperin compositions mdck cell is respectively 1.2g ± 0.11g/L.(3). after nuezhenoside, hyperin compositions made serial dilution, the 100TCID50 influenza virus is carried out inhibition test, median effective dose IC50 and the TI value of calculating medicine are big or small, and the result sees table 4.
Table 4. nuezhenoside, hyperin compositions are to the IC of FM1 influenza virus
50(g/L) and TI (x ± s)
Can be known that by table 4 IC50 of nuezhenoside, hyperin compositions is low, TI is high.Nuezhenoside, hyperin compositions suppress the cytopathogenic effect of FM1 influenza virus and all strengthen along with the increase of drug dose.Drug dose and medicine are shown that to the correlation analysis that the suppression ratio of CPE carries out the dosage of nuezhenoside, hyperin compositions and medicine are to being tangible positive correlation between the CPE suppression ratio.
