Taw qhia

N-Boc-L-Tyrosine Methyl Ester yog cov tshuaj lom neeg uas nws lub npe tshuaj yog N-tert-butoxycarbonyl-L-tyrosine methyl ester. Nws cov khoom yog raws li nram no:

 

1. Cov tsos: dawb mus rau grey crystalline khoom;

5. Solubility: soluble hauv organic solvents xws li ethanol thiab dimethylformamide (DMF), insoluble hauv dej.

 

N-Boc-L-tyrosine methyl ester feem ntau yog siv rau hauv cov organic synthesis los tiv thaiv cov amino acids nyob rau hauv cov synthesis ntawm polypeptide tebchaw. Nws yog feem ntau siv los ua ib pab pawg tiv thaiv L-tyrosine los tiv thaiv cov tshuaj tiv thaiv uas tsis yog tshwj xeeb hauv cov tshuaj tiv thaiv tshwm sim. Thaum cov tshuaj tiv thaiv tiav, cov pab pawg tiv thaiv tuaj yeem raug tshem tawm raws li qhov tsim nyog kom tau txais cov khoom lag luam zoo tshaj plaws.

 

Txoj kev npaj ntawm N-Boc-L-tyrosine methyl ester feem ntau suav nrog cov kauj ruam hauv qab no:

 

1. Dissolve L-tyrosine hauv dimethylformamide (DMF);

2. Ntxiv sodium carbonate rau neutralize carboxyl pawg ntawm tyrosine;

3. Methanol thiab methyl carbonate (MeOCOCl) yog ntxiv rau cov tshuaj tiv thaiv sib tov los tsim N-Boc-L-tyrosine methyl ester. Cov tshuaj tiv thaiv feem ntau yog ua los ntawm qhov kub thiab txias, thiab ntau tshaj ntawm methyl carbonate yog siv los xyuas kom meej tias cov tshuaj tiv thaiv tau tshwm sim.

 

N-Boc-L-tyrosine methyl ester yog qhov ruaj khov, tab sis nws tseem yuav tsum tau ceev faj. Cov hauv qab no yog cov ntaub ntawv kev nyab xeeb dav dav:

 

1. Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag: Cov hnab looj tes tiv thaiv tsim nyog thiab tsom iav yuav tsum hnav kom tsis txhob muaj kev sib cuag ncaj qha nrog cov khoom sib xyaw;

2. Tsis txhob nqus pa: yuav tsum ua kom muaj cua zoo hauv qhov chaw ua haujlwm kom tsis txhob nqus cov pa roj;

3. Cia: Nws yuav tsum muab cia rau hauv qhov chaw txias, qhuav thiab tsis txhob sib cuag nrog cov pa oxygen, muaj zog acids, lossis cov hauv paus muaj zog.

 

Zuag qhia tag nrho, N-Boc-L-tyrosine methyl ester yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm peptide compounds. Kev saib xyuas yuav tsum tau ua kom muaj kev nyab xeeb thaum siv thiab tuav.
