4-Methylumbelliferon (4-MU; 7-Hydroxy-4-Methylcoumarin) (CAS: 90-33-5), hydroxycoumarin yomwe imalowetsedwa ndi gulu la methyl pamalo a 4.
4-Methylumbliferon ndi zakudya zowonjezera zomwe zimalepheretsa kaphatikizidwe ka hyaluronic acid (HA).Hyaluronan (HA) ndi gawo lodziwika bwino la matrix a extracellular m'malo ambiri otupa osatha, kuphatikiza matenda a shuga 1 (T1D), multiple sclerosis, ndi zilonda zambiri.4-MU ndi mankhwala ovomerezeka kale ku Ulaya ndi Asia otchedwa "hymecromone" kumene amagwiritsidwa ntchito pochiza biliary spasm.
Choloretic, spasmolytic, sunscreen, analytical reagent.
Kugwiritsa Ntchito Mankhwala: 4-Methylumbelliferon imagwiritsidwa ntchito makamaka popanga mankhwala opangira mankhwala komanso ngati nyumba yopangira ma probes a fulorosenti.Ntchito zikuphatikizapo kaphatikizidwe wa: coumarin triazole zotumphukira monga kuthekera antimicrobial wothandizira.coumarin salen-based fluorescence sensors kuti azindikire Mg2+.pyranocoumarin zotumphukira monga anti-hyperglycemic ndi anti-dyslipidemic agents.coumarin piperazine zotumphukira monga zotheka multireceptor atypical antipsychotics.4-methylumbelliferyl T-antigen ngati gawo lapansi la endo-α-N-acetylgalactosaminidase.
Biological Activity 4-methylumbelliferone ndi hyaluronic acid (ha) synthesis inhibitor.kutsegulira kwa has2 ndi kuchulukitsidwa kwa ma ha kulipo m'mizere yambiri yama cell chotupa cha metastatic.Kuwonjezeka kwa kaphatikizidwe ka ha nthawi zambiri kumalumikizidwa ndi kuchuluka kwamphamvu kwa metastatic komanso kusokoneza ma cell chotupa.
