Conclusion: in the injection kutkin I body dhbv dna is had than the obvious suppression effect.
Test nine injection kutkin Is to the inhibiting in vitro study of hepatitis B virus
Whether observation in vitro injection kutkin I is inhibited to hepatitis B virus (HBV).Detect the toxicity of injection kutkin I with mtt assay to the 2.2.15 cell; Detect the content that variable concentrations injection kutkin I acts on behind the 2.2.15 cell different time HBV related antigen-surface antigen (HBsAg) and e antigen (HBeAg) in the cells and supernatant, the half toxic concentration (TC of calculating medicine pair cell with the ELISA method
50) and to antigenic half-inhibition concentration (IC
50), with TC
50And IC
50Ratio (being therapeutic index) estimate the effectiveness and the safety of medicine, TI>2 are safe and effective.The normal control group is set simultaneously, blank group, and positive drug lamivudine (3TC) group operation repetitive.The results are shown in following table.
Table 20 injection kutkin I is to the therapeutic index of HbsAg and HBsAg
Medicine | TI to HBsAg | TI to HBsAg |
Batch | 1 | 2 | 3 | 1 | 2 | 3 |
Injection kutkin I 3TC | 2.0 5.2 | 5.0 5.4 | 1.9 3.3 | 4.8 - | 5.2 1.7 | 4.5 - |
Annotate: criterion is: TI>2 are for effective; 1≤TI≤2 are poisonous effective; TI<1 is a toxic action.
The explanation of above-mentioned experimental result: the three batches of experiment injection kutkin Is are respectively 2.97 and 4.83 to the meansigma methods of HBsAg and HBeAg therapeutic index; The positive drug lamivudine is 4.83 to the therapeutic index of HBsAg, and HBeAg is not had inhibitory action.
Conclusion: the injection kutkin I is external to have the obvious suppression effect to HBV.
The pharmacodynamic experiment result shows that kutkin I not only has the liver protecting and ALT lowering, promoting the function of the gallbladder to alleviate jaundice and immunoregulation effect preferably, but also has significant anti-HBV effect.
In order to study the toxic action that kutkin I may exist body, estimate the drug safety that utilizes the Chinese medicine medicine that this monomer is prepared into, the inventor has carried out the general toxicity experiment and specific toxicity is tested.
One, general toxicity experiment
1. studies on acute toxicity
Experimental result shows the LD of the injection type intravenous administration of kutkin I to mice
50Value is 1040mg/kg, and intravenous administration is to the LD of rat
50Value is 171.4mg/kg, and intraperitoneal injection is to the LD of rat
50For the 552mg/kg medicine does not have obvious acute toxicity damage to the vital tissue of animal and internal organs.
2. long term toxicity research
(1) kutkin I injection type intraperitoneal injection is to the long term toxicity research of rat
Establish 4 groups altogether, be respectively solvent control group (equal-volume normal saline), the little 40mg/ (kgd) of kutkin I injection type, middle 150mg/ (kgd) and big three dosage groups of 300mg/ (kgd) are equivalent to 5 times, 21 times, 42 times of pharmacodynamics effective dose respectively.With general performance, body weight, food ration, hematology and serum biochemistry index, routine urinalysis, bone marrow classification, organ weights, organ coefficient before and after the animals administer serves as to detect index, and be aided with the pathological examination that animal is respectively organized internal organs, the toxicity situation of overall merit medicine.The result shows that the heavy dose of treated animal body weight gain of kutkin I injection type is slow, and all the other every indexs are all normal.In, every detection index of small dose group animal also shows no obvious abnormalities.The result of histopathologic examination shows that three dosage treated animals are respectively organized the internal organs no abnormality seen.Be safe dose in can thinking below the dosage.
(2) kutkin I injection type intravenous drip administration is to the long term toxicity research of Beagle
Establish 4 groups altogether, be respectively solvent control group (equal-volume normal saline), the little 20mg/ of kutkin I injection type (kgd), middle 77.46mg/ (kgd) and big three dosage groups of 150mg/ (kgd).Be equivalent to 10,40 and 70 times of pharmacodynamics effective dose respectively.Observation index is the same.The result shows that the every detection index of large, medium and small dosage treated animal is no abnormality seen also.The pathology detection results suggest, three each vital tissue internal organs Non Apparent Abnormalities of dosage treated animal.
Comprehensive above-mentioned two long term toxicity results of study, we think that injection kutkin I toxicity is lower, safety range is wide, considerably beyond the scope of pharmacodynamics effective dose.
Two, specific toxicity experiment
1. the mutagenic action of kutkin I research
Studied the potential in vitro and in vivo mutagenicity of kutkin I respectively by " Salmonella typhimurium back mutation experiment ", " experiment of Chinese hamster lung fibroblast (CHL) chromosomal aberration " and " mouse bone marrow cells is had a liking for the polychromatocyte micronucleus and formed experiment ".The result shows, no matter kutkin I in external still body, does not all have significantly direct or indirect mutagenic action.
2. the Study on Teratogenic of kutkin I
Observe kutkin I at rat sensitive period to teratogenic agent successive administration by the sensitive period to teratogenic agent reproductive toxicity test of kutkin I, but whether the teratogenesis fetal hair (Crinis Carbonisatus) is given birth to.The result shows that each dosage of kutkin I does not all have tangible teratogenesis.
In sum, the kutkin I toxic and side effects is less, pharmacological action is clear and definite, it not only has the liver protecting and ALT lowering, promoting the function of the gallbladder to alleviate jaundice and immunoregulation effect preferably, but also has significant anti-HBV effect, this is one of creative place of the present invention, is the not available characteristics of domestic like product.As injection, this drug effect is rapid, and acute hepatitis is had excellent curative in addition.As oral agents, its major advantage is less than toxicity such as Western medicine such as lamivudine, aciclovirs, should take for a long time.The above-mentioned kutkin I that experimental results show that is a kind of active compound that hepatitis B comprises the acute or chronic hepatitis B disease for the treatment of, and the pharmaceutical composition that contains kutkin I is the good medicine for the treatment of the hepatitis B disease simply.
Rhizoma Picrorhizae can adopt the method for artificial growth to breed at present, has guaranteed the steady sources of medical material, and is quality controllable, and a large amount of plantation can reduce production costs with exploitation.In view of China is hepatitis B big country, the medicine that kutkin I is developed to the treatment hepatitis B will have than wide market application prospect.
