H-Tle-OH, L-tert-Leucine (CAS 20859-02-3) yog ib qho tseem ceeb amino acid ua ib feem peb ntawm peb cov leeg nqaij protein.L-tert-leucine yog ib qho tseem ceeb hauv kev tsim cov tshuaj chiral pharmaceutical active tshuaj.Nws kuj tseem siv tau rau kev tsim cov Chiral tridentate Schiff puag ligands.Nws yog nonproteogen chiral amino acid.Vim hais tias ntawm steric siab hindrance ntawm tert-butyl pab pawg neeg, cov derivatives ntawm tert-leucine yuav siv tau raws li cov qauv rau induce asymmetry nyob rau hauv asymmetric synthesis.Vim yog cov saw loj tert-butyl thiab nws cov hydrophobicity, nws tuaj yeem tswj tau cov molecular conformation nyob rau hauv lub synthesis ntawm polypeptides, thiab ua rau kom lub hydrophobicity ntawm polypeptides thiab stability ntawm enzymatic degradation.Peb lub tuam txhab tsim L-tert-leucine los ntawm cov txheej txheem enzymatic, cov tshuaj tiv thaiv mob me me, tsis yooj yim rau kev ua qias tuaj ib puag ncig.Nws tuaj yeem siv los ua Khoom Noj Khoom Haus, Khoom Noj thiab Pub Ntxiv Ntxiv;nws tuaj yeem siv rau cov tshuaj hluavtaws Anti-AIDs (Atazanavir Sulfate) thiab tshuaj tiv thaiv HCV (Telaprevir) thiab lwm yam L-tert-Leucine (CAS 20859-02-3) kuj tuaj yeem siv rau hauv peptide synthesis.
