N-Cbz-L-Threonine (CAS# 19728-63-3)
Ngozi ndi Chitetezo
| Zizindikiro Zowopsa | Xn - Zowopsa |
| Zizindikiro Zowopsa | R20/21/22 - Zowopsa pokoka mpweya, kukhudzana ndi khungu komanso kumeza. R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | S22 - Osapumira fumbi. S24/25 - Pewani kukhudzana ndi khungu ndi maso. S36 - Valani zovala zoyenera zodzitetezera. S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. |

N-Cbz-L-Threonine (CAS# 19728-63-3) Zambiri
| kukonzekera | onjezerani 50mL wa L-Thr(30mmol) ndi njira yoziziritsa ya Na2CO3 yosungunuka mu botolo la 250mL, ndikugwedeza ndi kusungunula mumadzi osambira. Dontho 20mL ya Z-OSu(39.4mmol) yankho la acetone mu botolo la zomwe zimachitika; Limbikitsani zomwe zimachitika pa 25 ℃, TLC-UV fluorescence ndi njira yamtundu wa ninhydrin kuwunika momwe zimachitikira. Pambuyo anachita, kuwonjezera H2O20mL, Tingafinye ndi Et2O (30mL × 2) pa pH>9, kusonkhanitsa amadzimadzi gawo, kusintha pH 3~4 ndi 1.5NHCl, Tingafinye ndi EtOAc(30mL × 3), kuphatikiza organic gawo, Sambani ndi zodzaza NaCl njira (25mL × 2), youma ndi anhydrous Na2SO4, fufuzani chiyero ndi TLC-ultraviolet fluorescence ndi ninhydrin mtundu chitukuko njira, ndi nthunzi nthunzi pansi pa kupanikizika, zingalowe kuyanika kupeza chikasu mafuta madzi N-benzyloxycarbonyl-L-threonine, amene amasungidwa kutentha otsika. |
| Gwiritsani ntchito | CBZ-L-threonine ndi N-Cbz yotetezedwa mawonekedwe a L-threonine (T405500). L-threonine ndi amino acid wofunikira ndipo amagwiritsidwa ntchito ngati chakudya komanso chowonjezera chazakudya. Mtundu wosinthika wa Escherichia coli umatulutsa kuchuluka kwa L-threonine pofufuza komanso zakudya zopatsa thanzi. L-threonine imapezeka mwachilengedwe mu nsomba ndi nkhuku ndipo imaphatikizidwa m'mapuloteni ofunikira amthupi, monga hemoglobin ndi insulin. Amagwiritsidwa ntchito kwa biochemical reagents ndi peptide synthesis. |
