Daim ntawv thov:

1-Hydroxybenzotriazole Hydrate (HOBt·H2O) (CAS: 123333-53-9; 80029-43-2), additives rau oligonucleotide couplings thiab nyob rau hauv racemization-dawb peptide couplings.
HOBt·H2O yog ib co coupling reagent siv los ua ke amides los ntawm cov condensation cov tshuaj tiv thaiv ntawm cov activated ester/acid thiab cov amino pawg tiv thaiv amino acids.Nws kuj yog siv los ua racemization suppressor thaum peptide synthesis.
Synthesis ntawm Ubenimex intermediates thiab polypeptide tiv thaiv.Nws yog dav siv nyob rau hauv condensation cov tshuaj tiv thaiv ntawm polypeptides nrog carbodiimide condensers, uas yuav txo tau cov racemization piv, thiab kuj yog siv los tiv thaiv zus tau tej cov racemization thaum lub sij hawm condensation ntawm polypeptide fragments.
HOBt yog ib qho zoo tshaj plaws suppressors ntawm racemization hauv carbodiimide-mediated tshua.Qhov teeb meem tseem ceeb tshaj plaws ntawm cov additive yog nyob rau hauv nws cov cim tawg, tshwj xeeb tshaj yog nyob rau hauv daim ntawv tsis muaj dej.Yog li ntawd, nws muaj ntau yam txwv niaj hnub no tab sis nws tuaj yeem hloov tau los ntawm cov khoom siv ruaj khov dua li OxymaPure thiab K-Oxyma.Polymer-bound HOBt yog siv rau kev tsim ntawm nruab nrab lub nplhaib lactams nrog DCC nyob rau hauv lub xub ntiag ntawm resin-bound esters thiab kuj rau amides synthesis.
