Entecavir (SQ 34676;I-BMS 200475) yi-HBV Inhibitor ekhethiweyo kwaye esebenzayo.Kwiiseli ze-HepG2 ixabiso le-EC50 yi-3.75 nM.Amachiza amva nje e-anti-hepatitis B kunye ne-anti-AIDS kwinqanaba lokuqala.
Isiphumo se-Entecavir
Le mveliso i-guanine nucleoside analog, enempembelelo yokuthintela kwi-virus ye-hepatitis B (HBV) polymerase.Inokuthi i-phosphorylated ibe yi-triphosphate esebenzayo, kunye nesiqingatha sobomi be-triphosphate kwiseli yiyure ezili-15.Ngokukhuphisana ne-HBV polymerase yendalo ye-substrate i-deoxyguanosine triphosphate, i-entecavir triphosphate inokuthintela yonke imisebenzi emithathu ye-polymerase ye-viral (reverse transcriptase): (1) i-HBV polymerase initiation;(2) i-pregenomic mRNA Ukuqulunqwa komtya ombi wokuguqulela umva;(3) Ukwenziwa komcu ovumayo we-HBV DNA.I-inhibitory constant (Ki) ye-entecavir triphosphate kwi-HBV DNA polymerase yi-0.0012μM.I-Entecavir triphosphate ine-inhibitory effect ebuthakathaka kwi-cell α, β, δ DNA polymerase kunye ne-mitochondrial γ DNA polymerase, kunye nexabiso le-Ki le-18 ukuya kwi-160 μM.
Chaza | Entecavir (SQ 34676;I-BMS 200475) iyakhetha kwaye iyasebenza i-HBV Inhibitor.Kwi-HepG2 iiseli EC50 ixabiso yi-3.75 nM. |

Ekujoliswe kuko | EC50: 3.75 nM (anti-HBV, HepG2 iseli)[2] |
I-In vitroizifundo | I-EC50 ye-BMS-200475 ukuya kwi-HBV yi-3.75 nM.Ifakwe kwi-HBV protein primers, kwaye emva koko inyathelo lokuqala le-reverse transcriptase liyathintelwa.Umsebenzi we-antiviral we-BMS-200475 usezantsi kakhulu kunezinye iintsholongwane ze-RNA kunye ne-DNA [1].Xa kuthelekiswa namanye ama-analogs e-deoxyguanosine (i-penciclovir, i-ganciclovir, i-lobulavir kunye ne-acyclovir) okanye i-lamivudine, i-entecavir inokuthi ibe yi-phosphorylated kwi-metabolite yayo esebenzayo.I-intracellular half-life of Entecavir yi-15 iiyure [2]. |
Kwi-vivouphando | I-BMS-200475 iphathwa ngomlomo imihla ngemihla kunye ne-dose ukusuka kwi-0.02 ukuya kwi-0.5 mg / kg ubunzima bomzimba kwi-1 ukuya kwiinyanga ze-3, ezinokunciphisa ngokufanelekileyo izinga le-woodchuck hepatitis virus (WHV) viremia kwi-woodchucks enesifo esingapheliyo [3]. |
Iseliumfuniselo | I-BMS 200475 ilungiswa nge-phosphate buffered saline (PBS) yaze yaxutywa ngesiphakathi esifanelekileyo esiqulethe i-2% ye-fetus bovine serum.Iiseli ze-HepG2 ze-2.2.15 zifakwe kwi-12-well ye-Biocoat i-collagen-coated plate kubuninzi be-5 × 10 iiseli ze-5 kwiqula ngalinye, kwaye zigcinwe kwindawo edibeneyo iintsuku ezi-2 ukuya kwezi-3, kwaye zigqunywe nge-1 mL ye-BMS 200475. phakathi .Ubalo lwe-HBV lwenziwa ngomhla we-10 [1]. |

Iinkcukacha ezongezelelweyo:
I-Qu Qiang (i-PhD kwi-pharmacology yekliniki, iSebe le-Pharmacy, iSibhedlele sase-Xiangya, iYunivesithi yaseMzantsi Afrika) kunye no-Wang Ruoguang (uGqirha wezoNyango, i-postdoctoral kwi-biology, i-Changsha Ruoguang Medical Research Centre) nayo yabhala ukuba: kwi-regimen ye-entecavir, i-entecavir inokuthathwa. iminyaka emininzi okanye iminyaka eyi-10.Ngaphezu kweminyaka.Kwaye inokusetyenziswa ngabasetyhini abakhulelweyo, ebonisa ukhuseleko oluhle.
Ukuqwalasela ezi ndlela zaziwayo ze-molecular pharmacological, i-Entecavir ingaba nefuthe elibanzi le-antiviral, elingasebenzi kuphela kwi-HBV.
Sisoloko sisebenzisa i-Entecavir ukunyanga izifo zentsholongwane yokuphefumula kwikliniki, kwaye umphumo uyamangalisa.
Okwangoku, kuhlalutyo lokubuyela emva kwezigulana ezingaphezu kwama-500 ze-COVID19 e-Hubei (indawo), ngumntu omnye kuphela owathatha i-entecavir.Ixesha elimiselweyo lalisekuqaleni kukaJanuwari, kwaye ke iyeza layekwa.
Ngelixa bexhasa abasebenzi bezonyango e-Hubei, abanye oogqirha abasezantsi, okanye amaqela asemngciphekweni omkhulu, ngoku asebenzisa i-Entecavir ukunqanda i-COVID19, akukho meko yosulelo.Abantu ekurhaneleka ukuba bathatha i-entecavir, akukho mntu uqhubele phambili wafunyaniswa ukuba une-COVID19.
Imiba yePatent:
Zimbini iinkqubo, 06 inkqubo kunye 89 inkqubo.Ukuphelelwa kwelungelo lomenzi wenkqubo ye-06 kusekude kakhulu (iphelelwa ngo-2023)!Nangona iindleko zenkqubo ziphantsi, umgangatho ulungile, kwaye abasebenzi banokuba namandla, iingcebiso zomntu: Kwizityalo zemichiza, sebenzisa inkqubo ye-06 ukuba ungabi nekratshi kakhulu;kwiinkampani ezixuba amayeza, musa ukuthatha i-fluke kwaye ungabi yingozi kakhulu.
Kwi-2014, i-Chia Tai Tianqing iphumelele kwiintengiso zonyaka ze-10 yezigidigidi ze-yuan ngokuthembela kumachiza aqhelekileyo afana ne-entecavir, apho i-entecavir ibalwa kwi-20%.
Ekubeni i-entecavir ivunyiwe ukuba ingeniswe kwi-2005, ngaphezu kweenkampani ze-100 zasekhaya zonyango ziye zafaka isicelo sokubhaliswa kwemveliso;phakathi kwabo, iinkampani zokuvelisa ezivunyiweyo ziquka i-Jiangsu Zhengda Tianqing Pharmaceutical (ukulinganisa kokuqala), i-Hainan Zhonghe Pharmaceutical, kunye ne-Fujian Guangxi Pharmaceutical Co., Ltd.
