N-Cbz-L-Leucine (CAS # 2018-66-8) selelekela

Cbz-L-leucine, lebitso le felletseng la Boc-L-leucine (Boc e emetse dibutoxycarbonyl sehlopha se sireletsang), ke motsoako oa amino acid. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

Boleng:
- Ponahalo: E tiileng ka kristale e tšoeu
- E qhibiliha ka har'a ethanol, dimethylformamide (DMF) le dichloromethane

Sebelisa:
- CBZ-L-Leucine ke sehlopha se atisang ho sebelisoa amino acid e sireletsang sehlopha sa hydroxyl ea leucine nakong ea tlhahiso ea li-peptide ho e thibela ho sebetsana le li-reactants tse ling. Ka peptide synthesis moo masala a mangata a leucine a hlokang ho hlahisoa, Cbz-L-leucine e ka sebelisoa ho sireletsa sehlopha sa hydroxyl sa leucine bakeng sa mekhoa e latelang ea synthesis.
- Leucine ke amino acid ea bohlokoa e phethang karolo ea bohlokoa sebopehong sa protheine le tšebetsong.

Mokhoa:
- Tokisetso ea Cbz-L-leucine hangata e fumanoa ka karabelo ea leucine le Boc-OSu (Boc—N-nitrocarbonyl-L-leucine). Karabelong eo, Boc-OSu e sebetsa joalo ka selelekela sa sehlopha se sireletsang mme e etsa karabelo ea esterification le leucine ho hlahisa Cbz-L-leucine.

Lintlha tsa Tšireletseho:
- Cbz-L-leucine ke k'hemik'hale 'me e lokela ho bolokoa ka nepo hole le ho khantša le li-oxidants.
- Nakong ea tšebeliso, qoba ho hema lerole la eona kapa ho kopana le letlalo le mahlo.
- Latela mekhoa e sireletsehileng ha u tšoara le ho boloka, 'me u apare lisebelisoa tse nepahetseng tsa ho itšireletsa tse kang liatlana tsa laborateng le tšireletso ea mahlo.
