4-Nitrophenyl Beta-D-glucuronide CAS: 10344-94-2

Kev Tshawb Pom Kev Ua Haujlwm ntawm β-glucuronidase: 4-NPBG feem ntau yog siv los ua cov khoom siv chromogenic los ntsuas qhov muaj thiab kev ua haujlwm ntawm β-glucuronidase hauv ntau yam qauv tshuaj lom neeg. Cov enzyme txiav cov glycosidic bond ntawm 4-NPBG, tsim 4-nitrophenol, uas tuaj yeem ntsuas tau siv spectrophotometry.

Kev tshawb fawb txog kev hloov pauv tshuaj: Vim tias β-glucuronidase ua lub luag haujlwm tseem ceeb hauv kev hloov pauv tshuaj thiab cov tshuaj xenobiotics, 4-NPBG tuaj yeem siv los ntsuas qhov kev ua haujlwm ntawm cov enzyme no hauv kev tshawb fawb txog kev hloov pauv tshuaj. Nws pab nkag siab txog qhov dav thiab kinetics ntawm glucuronidation reactions, uas yog qhov tseem ceeb rau kev tshem tawm tshuaj thiab bioavailability.

Kev tshawb fawb txog kev lom: Qee cov tshuaj lom tuaj yeem raug metabolized thiab excreted ua glucuronide conjugates. Los ntawm kev siv 4-NPBG ua ib qho substrate, cov kws tshawb fawb tuaj yeem tshuaj xyuas qhov kev ua haujlwm ntawm β-glucuronidase hauv cov nqaij sib txawv lossis cov kab cell kom ntsuas qhov muaj peev xwm lom lossis cov teebmeem tsis zoo ntawm cov tshuaj.

Kev kuaj mob hauv tsev kho mob: Kev ntsuas kev ua haujlwm ntawm β-glucuronidase siv 4-NPBG tuaj yeem siv rau hauv kev kho mob los kuaj mob qee yam kab mob lossis mob. Cov qib lossis kev ua haujlwm tsis zoo ntawm β-glucuronidase yuav qhia txog qee yam kab mob caj ces, kev ua haujlwm tsis zoo ntawm daim siab, lossis mob qog noj ntshav.
