Synthesize entecavir ua ib qho nruab nrab
Entecavir belongs rau chav kawm ntawm deoxyguanosine nucleoside analogues. Nws exerts nws cov tshuaj tiv thaiv kab mob los ntawm inhibiting HBV DNA polymerase, yog li thaiv cov primer extension thiab saw elongation. Cov txheej txheem ntawm kev ua haujlwm no ua rau nws muaj txiaj ntsig zoo hauv kev tawm tsam HBV rov ua dua. Qhov tshwj xeeb, Entecavir tau ua kom pom qhov zoo tshaj plaws ntawm Lamivudine, lwm tus neeg sawv cev tiv thaiv kab mob, los ntawm kev ua tau zoo ntawm Lamivudine -cov kab mob HBV tiv taus thiab nthuav tawm 30 lub zog ntau dua.
Daim ntawv nquag ntawm Entecavir, nws cov triphosphate derivative, muaj ib nrab ntawm cov cellular ntev -lub neej ntawm 15 teev. Los ntawm kev sib tw nrog ntuj substrate deoxyguanosine triphosphate rau HBV polymerase.
Entecavir siv inhibitory cuam tshuam rau tag nrho peb lub luag haujlwm ua haujlwm ntawm viral polymerase, uas yog qhov pib ntawm HBV polymerase, rov qab hloov pauv hloov kho qhov tsis zoo-strand tsim los ntawm pregenomic mRNA, thiab zoo-strand synthesis ntawm HBV DNA.Phase II / III kev soj ntsuam kuaj pom tau hais tias ib hnub twg qhov ncauj koob tshuaj ntawm 0.5. xa cov txiaj ntsig kho tau zoo dua piv nrog lamivudine. Raws li Phase III cov ntaub ntawv kho mob, kev nce qib ntawm cov koob tshuaj txhua hnub mus rau 1 mg ua tiav inhibition ntawm HBV DNA replication nyob rau hauv cov neeg mob nqa YMDD kev hloov pauv.Rau cov neeg mob kho-naive, qhov tshwm sim ib xyoos ntawm kev siv tshuaj tiv thaiv tseem yog xoom. Los ntawm qhov sib txawv, ntawm cov neeg mob uas muaj kev hloov pauv YMDD ua ntej, ib xyoos kev siv tshuaj tiv thaiv nce mus txog 5.8%.
Pom zoo los ntawm yav dhau los Lub Xeev Saib Xyuas Khoom Noj thiab Tshuaj (SFDA, tam sim no NMPA) ntawm Tuam Tshoj rau kev kho cov neeg mob uas muaj kab mob siab B, entecavir ntiav 4-methoxytriphenylchloromethane ua ib qho ntawm nws cov khoom siv hluavtaws tseem ceeb. Zoo li txhua tus neeg sawv cev tshuaj, entecavir yog txuam nrog qee yam tsis zoo. Cov kev kho mob tshwm sim muaj xws li mob taub hau, kiv taub hau, qaug zog, xeev siab thiab mob plab; Cov tsos mob no feem ntau me me mus rau nruab nrab ntawm qhov hnyav thiab zoo li yuav txo qis thaum kho txuas ntxiv mus. Txawm hais tias tsis tshua muaj tshwm sim, qhov tshwm sim loj dua xws li lactic acidosis thiab lub raum tsis ua haujlwm yuav tsum tau saib xyuas kev soj ntsuam ze, tshwj xeeb ntawm cov neeg mob uas muaj kab mob siab heev.
Hauv cov ntsiab lus, Entecavir yog ib qho kev xaiv thiab ua tau zoo HBV inhibitor nrog rau qhov zoo -tsim kom muaj kev nyab xeeb profile thiab tus nqi qis. Nws tseem yog thawj - txoj kev kho kab mob siab rau kab mob siab B, ua rau muaj txiaj ntsig zoo rau kev tswj hwm thiab txhim kho cov neeg mob lub siab noj qab haus huv.
4-methoxytriphenylchloromethane hmoovs ib qho organic compound featuring chemical yam ntxwv. Nyob rau hauv lub ambient kub thiab atmospheric siab, nws tshwm sim raws li ib tug off-dawb mus rau xim liab. Lub compound qhia zoo solubility nyob rau hauv dav-siv organic solvents xws li ethyl acetate, dichloromethane thiab dimethyl sulfoxide, thaum nws tseem xyaum insoluble nyob rau hauv dej. Nws cov pab pawg reactive chlorinated ua rau nws muaj ntau yam khoom siv hluav taws xob tsim thaiv rau cov organic thiab kws tshuaj cuam tshuam txog kev ua haujlwm.
Kev siv tseem ceeb yog ua hydroxyl tiv thaiv reagent. Hauv kev sib xyaw ua ke ntawm cov organic, ntau cov tshuaj tiv thaiv yuav tsum muaj cov pab pawg ua haujlwm tshwj xeeb, thiab cov pab pawg hydroxyl (- OH), vim lawv cov reactivity siab, feem ntau yuav tsum tau tiv thaiv thaum cov txheej txheem tshuaj tiv thaiv los tiv thaiv lawv los ntawm kev koom nrog cov tshuaj tiv thaiv tsis tsim nyog.
