Molecular qauv thiab muaj pes tsawg leeg

Lub npe tshuaj ntawmribavirin hmoovyog 1 - - D - furanose - 1H - 1,2, 4 - triazole - 3 - formamide. Nws cov qauv molecular muaj ib lub nplhaib furanose, ib lub nplhaib triazole, thiab ib pawg formamide. Cov qauv tshwj xeeb no ua rau nws muaj cov tshuaj lom neeg thiab cov dej num tshwj xeeb. Lub nplhaib furanose endows nws nrog ib qho℃ntawm hydrophilicity, ua rau nws cuam tshuam nrog dej molecules hauv lub cev, uas yog qhov zoo rau kev sib cais ntawm cov tshuaj thiab nws cov kev thauj mus los hauv lub cev; lub nplhaib triazole thiab pawg formamide yog cov txheej txheem tseem ceeb uas ua rau nws siv nws cov tshuaj tiv thaiv kab mob, koom nrog kev cuam tshuam nrog tus kab mob{10}}txog lub hom phiaj.

Tshuaj stability

 

Stability rau lub teeb thiab cua sov

Ribavirin yog qhov tseem ceeb rau lub teeb thiab kub. Nyob rau hauv lub teeb pom kev zoo, tshwj xeeb tshaj yog nyob rau hauv ultraviolet hluav taws xob, cov tshuaj molecules tej zaum yuav undergo photochemical tshua, ua rau cov kev hloov nyob rau hauv lub molecular qauv thiab tsim ntawm ib co inactive los yog toxic degradation khoom. Piv txwv li, lub nplhaib triazole lossis furan ribose nplhaib tuaj yeem raug lub nplhaib - qhib, oxidation thiab lwm yam kev cuam tshuam, yog li txo cov tshuaj tiv thaiv kab mob. High - qhov kub thiab txias ib puag ncig kuj tseem yuav ua kom cov tshuaj tiv thaiv decomposition ntawm cov tshuaj, cuam tshuam rau nws txoj kev ruaj ntseg thiab kev ua tau zoo. Yog li ntawd, thaum lub sij hawm cia thiab thauj cov tshuaj, nws yog ib qho tsim nyog yuav tsum tau txais cov xwm txheej ntawm kev zam lub teeb thiab qhov kub thiab txias, xws li khaws cov tshuaj hauv cov fwj xim av thiab muab tso rau hauv qhov chaw txias thiab qhuav kom ntev lub txee lub neej ntawm cov tshuaj.

Stability rau acids thiab bases

Hauv cov kua qaub sib txawv- puag ncig, qhov ruaj khov ntawm ribavirin sib txawv. Nyob rau hauv acidic tej yam kev mob, cov tshuaj yuav undergone hydrolysis cov tshuaj tiv thaiv, uas ua rau kev puas tsuaj ntawm molecular qauv. Piv txwv li, pab pawg amide tuaj yeem raug hydrolysis nyob rau hauv ib puag ncig acidic, tsim cov carboxylic acids thiab amine tebchaw, yog li poob cov tshuaj tiv thaiv kab mob. Nyob rau hauv cov xwm txheej alkaline, cov tshuaj kuj tuaj yeem ua rau qee yam tshuaj lom neeg, xws li lub nplhaib - qhib lub nplhaib furan ribose. Yog li ntawd, nyob rau hauv kev npaj ntawm formulations, tsim nyog pH tej yam kev mob yuav tsum tau xaiv los xyuas kom meej stability ntawm cov tshuaj. Tus nqi pH ntawm qhov ncauj formulations feem ntau yuav tsum tau tswj nyob rau hauv ib tug tej yam ntau yam kom tsis txhob muaj ntau dhau ntawm cov kua qaub- puag ncig ntawm cov tshuaj nyob rau hauv lub plab hnyuv ib ntsuj av.

 

Kev ua haujlwm pab pawg kev xav

Cov pab pawg ua haujlwm hauv ribavirin molecule muaj qee yam tshuaj reactivity. Piv txwv li, cov pab pawg amide tuaj yeem koom nrog qee qhov kev hloov pauv nucleophilic, acylation cov tshuaj tiv thaiv, thiab lwm yam. Hauv kev tshawb fawb tshuaj, cov kev ua haujlwm ntawm pawg neeg no tuaj yeem siv los hloov kho ribavirin thiab sib txuas cov derivatives nrog ntau yam tshuaj tiv thaiv kab mob thiab cov tshuaj pharmacokinetic los tshawb nrhiav cov tshuaj zoo thiab nyab xeeb dua.

Cov tshuaj tiv thaiv nrog hlau ions

Ribavirin tuaj yeem tsim cov complexes nrog qee cov hlau ions. Cov tshuaj tiv thaiv no tuaj yeem cuam tshuam rau kev solubility, kev ruaj ntseg thiab kev ua haujlwm lom neeg ntawm cov tshuaj. Piv txwv li, complexes tsim nrog calcium, magnesium thiab lwm yam hlau ions yuav txo tau qhov nqus ntawm cov tshuaj nyob rau hauv lub plab hnyuv ib ntsuj av, yog li cuam tshuam cov kev ua tau zoo ntawm cov tshuaj. Yog li ntawd, nyob rau hauv kev npaj thiab kev kho mob ntawm formulations, yuav tsum tau them nyiaj mloog mus rau kev sib cuam tshuam ntawm cov tshuaj thiab hlau ions kom tsis txhob muaj kev cuam tshuam cov nyhuv ntawm cov tshuaj vim complexation tshuaj.
