Isicelo
I-Dibutyryl cyclic adenosine monophosphate sodium iphuma ku-cyclic adenosine monophosphate, esetshenziselwa ukwelapha ukushaqeka kwe-cardiogenic nokuhluleka kwenhliziyo.Ngo-1999, i-Dibutyryl cyclic adenosine monophosphate ointment sodium yasungulwa ukwelapha izifo zesikhumba kanye nezilonda zesikhumba.
Ukulungiswa kwe-sodium dibutyryl cyclophosphate adenosine: Eflaskini eliqukethe i-cyclophosphate adenosine kancane engeza isixazululo se-aqueous sodium hydroxide (3 mol/L) dropwise, izinga lokushisa elilawulwa inqubo, ukufudumala okuphansi kuqedile ekamelweni lokushisa, lungisa i-pH ibe 7 ~ 8 ngesisombululo se-HCl ( 20%), engeza i-anhydrous ethanol kwezulu eliqinile elimhlophe, filtration, omiswe ukuze uthole usawoti oqinile wesodium emhlophe;usawoti we-sodium kanye ne-n-butyl anhydride ngaphansi kokuvikelwa kokufudumala kwe-N2 kuya ku-140 ℃ ukusabela.Ukuqapha kwe-TLC, ukusabela kuphelile bese kwehliselwa ekamelweni lokushisa, kancane kancane engeza i-methyl tert-butyl ether, inqubo yokunyakazisa ngamandla, i-Chemicalbook ukuthola umkhiqizo ocishe umhlophe oqinile ongahluziwe.Ingxube ye-methyl tert-butyl ether kanye ne-acetone yaphinde yamiswa ukuze kutholwe umkhiqizo ohlosiwe oyimpuphu emhlophe.Umsebenzi webhayolojiI-Dibutyryl-cAMP(Bucladesine,dbcAMP) iyi-activator ye-PKA ekwazi ukungena ngeseli esebenza ngokulingisa i-endogenous cAMP.I-Dibutyryl-cAMP(Bucladesine) iphinde ibe yi-phosphodiesterase(PDE) inhibitor.
Izifundo ze-in vitro:I-Dibutyryl-cAMP ivimbela ukutholwa kwe-neuronal glucose ngokuvula i-PKA.Kuma-hepatocyte amagundane akhulisiwe, i-Dibutyryl-cAMP ivimbela inkulumo ye-inducible nitric oxide synthase kanye nomsebenzi wokubopha i-NF-kappaB.I-dibutyrChemicalbookyl-cAMP iphinde ivimbele i-apoptosis yeseli yenduku eyenziwe yi-TNFalpha ngokuvimbela ukulawulwa kwe-FADD.
Izifundo ze-vivo:Kumodeli yegundane, i-Bucladesine (600nM/igundane,ip) ihlehlise i-zinc chloride kanye nokonakala kokugcinwa kwenkumbulo okuvalekile okudalwe i-acetate.
