Daim ntawv thov:

5-Benzyl L-Glutamate N-Carboxyanhydride (H-Glu (OBzl)-NCA) (CAS: 3190-71-4) yog siv los ua cov tshuaj intermediates.H-Glu(OBzl)-NCA tuaj yeem siv los ua tus nruab nrab ntawm Glatiramer Acetate (CAS: 147245-92-9).Glatiramer Acetate yog ib qho yooj yim hluavtaws copolymer ntawm L-alanine, L-lysine, l-glutamic acid thiab L-tyrosine nyob rau hauv ib tug molar ratio ntawm 6: 1.9: 4.7: 1.Glatiramer acetate yog ib qho immunomodulator siv los kho ntau yam sclerosis.5-Benzyl L-Glutamate N-Carboxyanhydrideyog ib qho reactive derivative ntawm L-glutamic acid, qhov twg cov amino acid tau cyclised li N-carboxyanhydride (NCA), chav kawm ntawm reagent hu ua Leuchs 'anhydrides.5-Benzyl L-Glutamate N-Carboxyanhydride reacts nrog nucleophiles xws li cawv thiab amines los ua esters thiab amides feem.Qhov qhib ntawm N-carboxyanhydride mus rau ib qho ester lossis amide tso tawm cov amino acid amine uas tuaj yeem ua rau muaj kev cuam tshuam los ntawm nucleophile ua rau polymerization.Cov poly-amide polymers no tau raug tshawb xyuas raws li kev xa khoom ntawm Small Interfering RNA (si-RNA).
