I-4-Methylumbelliferon (4-MU; 7-Hydroxy-4-Methylcoumarin) (CAS: 90-33-5) , i-hydroxycoumarin engu-umbelliferone esikhundleni seqembu le-methyl endaweni ye-4.
I-4-Methylumbliferon iyisengezo sokudla esivimbela ukuhlanganiswa kwe-hyaluronic acid (HA).I-Hyaluronan (HA) iyingxenye evelele ye-matrix engaphandle kweseli ezindaweni eziningi zokuvuvukala okungapheli, okuhlanganisa uhlobo 1 lwesifo sikashukela (T1D), i-multiple sclerosis, kanye nenqwaba yezifo ezimbi.I-4-MU iyisidakamizwa esivele sivunyelwe eYurophu nase-Asia esibizwa ngokuthi "hymecromone" lapho sisetshenziselwa ukwelapha i-biliary spasm.
I-Choloretic, i-spasmolytic, i-sunscreen, i-reagent yokuhlaziya.
Izicelo Zemithi: I-4-Methylumbelliferon isetshenziswa ngokuyinhloko ekuhlanganiseni izinhlanganisela zokwelapha futhi njengesakhiwo sokwakha ama-fluorescent probes.Izicelo zihlanganisa ukuhlanganiswa kwe-: coumarin triazole derivatives njengama-antimicrobial agents angaba khona.Izinzwa ze-fluorescence ezisekelwe ku-coumarin salen zokutholwa kwe-Mg2+.I-pyranocoumarin derivatives njengama-anti-hyperglycemic kanye nama-anti-dyslipidemic agents.I-coumarin piperazine derivatives njengama-antipsychotics angaba khona e-multireceptor atypical.I-4-methylumbelliferyl T-antigen njenge-substrate ye-endo-α-N-acetylgalactosaminidase.
I-Biological Activity 4-methylumbelliferone iyi-hyaluronic acid (ha) synthesis inhibitor.ukwenziwa kusebenze kwe-has2 kanye nokukhiqizwa ngokweqile kwama-ha kukhona emigqeni eminingi yamaseli e-metastatic tumor.ukwanda kokuhlanganiswa kwe-ha kuvame ukuhlotshaniswa nokukhuphuka kwamandla e-metastatic kanye nokuhlasela kwamaseli wesimila.
