{{0 {{}} bromo -2-} Cyanopyridineyog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv hluav taws xob nrog rau cov qauv kev sib xyaw ua ke, thiab cov khoom siv tshuab hluav taws xob yog} Nws yog ib tus lej ntawm lub nplhaib. Xaus nws nrog cov kev ua yeeb yam nplua nuj thiab muaj ntau yam kev tawm tsam, ua kom pom cov ntawv thov tseem ceeb hauv ntau thaj teb:
Daim Ntawv Thov Hauv Thaj Chaw Tshuaj Txhim Kho
Cov pawg pyridine thiab ob pawg carboxyl hauv 3, {pyridine carboxylic cov tshuaj lom neeg los ntawm cov tshuaj tiv thaiv ntau yam los ntawm kev siv tshuaj tiv thaiv ntau yam xws li Esterification, Kev Ua Haujlwm, thiab Decarboxylation, muab txoj kev nplua nuj rau kev hloov kho thiab cov roj ntsha ua ke nrog cov neeg muaj dej cawv, yog li kev haus cawv thiab roj ntsha ua haujlwm thiab roj ntsha cov molecules . lwm pab tau hloov pauv mus rau hauv pawg amino actively pyridine 3, {{4- pyridenedioxyacid ua qhov zoo ntawm cov tshuaj tiv thaiv me me, thiab muaj ntau yam tshuaj tiv thaiv kev ua haujlwm.
Siv rau kev hloov kho qauv qauv thiab ua kom zoo ntawm cov tshuaj molecules
Cov kws kho mob ntawm cov tshuaj, xws li solubility, lipophilicity, thiab lwm yam, muaj kev cuam tshuam nrog cov qauv tshuaj moleculic los ntawm tshuaj lom neeg cov tshuaj tiv thaiv, Txhim kho lawv lub pob physicochemical. Piv txwv li cov pab pawg hauv cov tshuaj esterification tuaj yeem ua rau cov tshuaj esterification tuaj yeem ua rau lawv cov permeability ntawm cov tshuaj ntxuav cell; Los ntawm kev qhia txog cov pab pawg hydrophylic xws li pawg neeg muaj txiaj ntsig, cov roj hmab ua kom tau nce ntxiv, thiab cov kev sib nqus ntawm cov pa roj ntsha tuaj yeem ua rau muaj dej cawv ua ke nrog cov dej cawv Prodrugs nrog cov dej ua kua loj {{8} Cov kws ua yeeb tshuaj, yog kev tso tshuaj lom neeg muag tshuaj, yog li nce cov tshuaj pharmetailability ntawm cov tshuaj {{9}
