N-Cbz-L-Threonine (CAS# 19728-63-3) Macluumaad

diyaarinta ku dar 50ml L-Thr (30mmol) oo la qaboojiyey xal Na2CO3 oo buuxa dhalada falcelinta 250mL, oo ​​walaaq oo ku milmi qubeyska barafka. Ku rid 20ml ee Z-OSu(39.4mmol) xal acetone dhalada falcelinta; Ku walaaq falcelinta 25 ℃, TLC-UV fluorescence iyo habka midabka ninhydrin la soco habka falcelinta. Dareen-celinta ka dib, ku dar H2O20mL, soo saar Et2O (30mL × 2) at pH> 9, soo qaado wejiga aqueous, hagaajin pH ilaa 3 ~ 4 oo leh 1.5NHCl, soo saar EtOAc (30mL × 3), isku dar wajiga organic, ku dhaq xal NaCl buuxa (25mL × 2), ku qallaji Na2SO4 anhydrous ah, hubi nadiifnimada adigoo isticmaalaya TLC-ultraviolet fluorescence iyo habka horumarinta midabka ninhydrin, iyo uumi-baxa cadaadiska hoos u dhaca, vacuum engejinta si aad u hesho dareere saliid ah oo huruud ah N-benzyloxycarbonyl-L-threonine, kaas oo lagu kaydiyo heerkul hoose.
Isticmaal CBZ-L-threonine waa qaabka la ilaaliyo ee N-Cbz ee L-threonine (T405500). L-threonine waa amino acid lagama maarmaan ah waxaana caadi ahaan loo isticmaalaa quudin iyo wax lagu daro cuntada. Nooca mutant ee Escherichia coli wuxuu soo saaray tiro badan oo L-threonine ah oo loogu talagalay cilmi-baarista iyo ujeedooyinka nafaqada. L-threonine ayaa si dabiici ah looga helaa kalluunka iyo digaaga waxaana lagu daraa qaar ka mid ah borotiinnada muhiimka ah ee jirka, sida hemoglobin iyo insulin.
Loo isticmaalo reagents biochemical iyo synthesis peptide.
