Den h\u00e6mmende effekt af boghvede-bipollen-polyfenoler p\u00e5 alfa-amylase
\nBipollen er et granuleret stof, som dannes, n\u00e5r arbejderbierne samler plantepollen og blander det med spyt og nektar. Bipollen er rig p\u00e5 n\u00e6ringsstoffer og er kendt som \"den universelle n\u00e6ringsstofbank\", hvilket g\u00f8r det til et naturligt kosttilskud af h\u00f8j kvalitet. Forskningen viser, at bipollen spiller en vigtig rolle i at reducere blodsukker og fedt, forbedre immuniteten, h\u00e6mme prostatasygdomme, forebygge kr\u00e6ft og anti-cancer osv. For eksempel har rapspollen den effekt, at det reducerer blodsukkeret in vitro, og kamelia-bipollen har den effekt, at det reducerer blodsukkeret i diabetesmodelmus; Bipollenekstrakt kan ogs\u00e5 h\u00e6mme prostatahyperplasi hos mus med godartet prostatahyperplasi. Bipollenpeptider kan forbedre den humorale og cellul\u00e6re immunfunktion hos immunkompromitterede mus. Bipollens funktion er relateret til de forskellige bioaktive komponenter, den indeholder, s\u00e5som polyfenoler, flavonoider, polysaccharider, peptider osv. Blandt dem er polyfenoliske forbindelser en af de vigtigste aktive komponenter i bipollen.
\nPolyfenoliske forbindelser omfatter prim\u00e6rt anthocyaniner, flavonoider, flavonoler, fenoliske syrer, tanniner og andre stoffer, som har kliniske anvendelsesmuligheder. En af de vigtigste anvendelser er udviklingen af funktionelle f\u00f8devarer, der hj\u00e6lper med at s\u00e6nke blodsukkeret. Mange rapporter har vist, at plantepolyfenoler kan reducere blodsukkeret hos diabetesmus, s\u00e5som sophora japonica-polyphenoler, vilde Lonicera japonica-polyphenoler, bl\u00e5b\u00e6rblad-polyphenoler osv. De kan reducere blodsukkeret ved at h\u00e6mme vigtige enzymer i blodsukkermetabolismen. Polyfenoler, som er vigtige aktive ingredienser i bipollen, har ogs\u00e5 hypoglyk\u00e6misk aktivitet. Flavonoider kan give hypoglyk\u00e6miske effekter ved at h\u00e6mme den katalytiske aktivitet af forskellige vigtige enzymer, der er involveret i blodsukkerkontrol, s\u00e5som alfa-amylase og alfa-glucosidase.<\/p>\n

\"\"\"\"\"\"\"\"\"\"\"\"
\nAlfa-amylase er et vigtigt enzym til at kontrollere blodsukkeret, som omdanner stivelse til maltose og glukose ved at virke p\u00e5 alfa-1,4-glykosidbindingerne i stivelse, hvilket f\u00f8rer til en hurtig stigning i det postprandiale blodsukkerniveau. Ved at h\u00e6mme aktiviteten af \u03b1-amylase for at reducere stivelsesford\u00f8jeligheden kan det forsinke stivelsesford\u00f8jelsen, h\u00e6mme tarmens absorption af glukose, effektivt regulere blodsukkerniveauet i kroppen og dermed lindre symptomerne p\u00e5 diabetes. At tage \u03b1-amylase som terapeutisk m\u00e5l for type 2-diabetes har derfor produceret en r\u00e6kke hypoglyk\u00e6miske l\u00e6gemidler, der anvendes i klinisk praksis, s\u00e5som acarbose, voglilitse, miglitol osv. Disse l\u00e6gemidler har dog alle visse bivirkninger, s\u00e5 der er et presserende behov for at udvikle naturlige hypoglyk\u00e6miske l\u00e6gemidler fra naturlige produkter. For at afklare muligheden for at anvende naturlige produkter som f.eks. polyphenoler fra bipollen til udvikling af naturlige hypoglyk\u00e6miske l\u00e6gemidler er det n\u00f8dvendigt at foretage en grundig unders\u00f8gelse af de h\u00e6mmende virkninger og molekyl\u00e6re mekanismer af polyphenoler fra bipollen p\u00e5 sukkermetabolismeenzymer.
\nSom en vigtig kornafgr\u00f8de er det blevet rapporteret, at boghvede har hypoglyk\u00e6miske virkninger, og polysaccharider fra boghvedepollen har ogs\u00e5 vist sig at have hypoglyk\u00e6misk aktivitet. Men polyfenoler, som er det vigtigste aktive stof i boghvedebiopollen, er ikke blevet unders\u00f8gt for deres hypoglyk\u00e6miske virkninger. I lyset af dette tager denne unders\u00f8gelse boghvede-bipollen-polyfenoler (BBPP) som forskningsobjekt og unders\u00f8ger dets h\u00e6mmende virkning og mekanisme p\u00e5 alfa-amylase ud fra tre aspekter: enzymkinetik, fluorescensspektroskopi og ultraviolet spektroskopi. Virkningerne af h\u00f8j temperatur, st\u00e6rk alkali, lys og h\u00f8j koncentration af oxidanter og reduktionsmidler p\u00e5 den h\u00e6mmende virkning af BBPP p\u00e5 alfa-amylaseaktivitet blev ogs\u00e5 udforsket. Dette eksperiment kan give et teoretisk grundlag for den omfattende udnyttelse af boghvede-bipollen og udviklingen af naturlige hypoglyk\u00e6miske l\u00e6gemidler og sammensatte formuleringer af alfa-amylaseh\u00e6mmere.
\nDette eksperiment anvendte forskellige spektroskopiske analyser og h\u00e6mningskinetik til at unders\u00f8ge BBPP's h\u00e6mmende mekanisme p\u00e5 alfa-amylase. Resultaterne viste, at BBPP udviste en st\u00e6rk og reversibel blandet konkurrenceh\u00e6mmende effekt p\u00e5 alfa-amylase, og dens h\u00e6mmende effektivitet var dosisafh\u00e6ngig med en IC50 p\u00e5 2,00 \u00b1 0,06 mg\/ml. Stabilitetsanalysen af BBPP under forskellige forhold viste, at h\u00f8j temperatur, st\u00e6rk alkali, lys og h\u00f8je koncentrationer af oxidanter og reduktionsmidler alle kunne reducere den h\u00e6mmende virkning af BBPP p\u00e5 alfa-amylase. Analyse af slukning af fluorescensspektrum viser, at BBPP udviser statisk slukning ved 273-298K og dynamisk slukning ved 298-310K, med kun \u00e9t bindingssted mellem de to. Synkron fluorescensspektroskopi indikerer, at BBPP for\u00e5rsager foldnings\u00e6ndringer i milj\u00f8et af \u03b1-amylase-tyrosinrester og \u00f8ger hydrofobiciteten. Denne artikel fokuserer p\u00e5 unders\u00f8gelsen af BBPP's h\u00e6mmende effekt p\u00e5 \u03b1-amylase som en hypoglyk\u00e6misk aktiv ingrediens til at lindre postprandial hyperglyk\u00e6mi. Senere vil vi unders\u00f8ge den hypoglyk\u00e6miske funktion af BBPP i diabetesmodeldyr og analysere og evaluere muligheden for at udvikle det som et hypoglyk\u00e6misk l\u00e6gemiddel.<\/p>\n
