I-Hazard Class Irritant
I-D-Tryptophan (HD-Trp-OH) (i-CAS: 153-94-6) i-D-form (ifomu elingelona i-proteinogenic) ye-amino acid tryptophan.Ama-amino acid kanye nokuphuma kokunye, asetshenziswa ku-peptide synthesis, asetshenziswa njenge-organic synthesis ephakathi, i-pharmaceutical intermediate, izithasiselo zokudla / okuphakelayo, isengezo sokudla okunempilo, i-biochemical reagent noma i-chemical reagent.
I-Tryptophan ingenye yama-amino acid angama-20 ajwayelekile, kanye ne-amino acid ebalulekile ekudleni komuntu.Ifakwe ikhodi kukhodi yofuzo evamile njenge-codon UGG.i-D-stereoisomer ngezinye izikhathi itholakala kuma-peptide akhiqizwa ngokwemvelo (isibonelo, i-marine venom peptide contryphan).Isici esihlukanisayo sesakhiwo se-Tryptophan ukuthi iqukethe iqembu elisebenzayo le-indole.Kuyi-amino acid ebalulekile njengoba kuchazwa imiphumela yayo yokukhula kumagundane.
I-D-Tryptophan amino acid, njengeprotheni engasebenzi, inezici ezikhethekile zomzimba.Ingasetshenziswa njengesithako esingenamsoco, isithasiselo sokuphakelayo, ama-ejenti okukhulisa izitshalo embonini yokudla kanye nezolimo.Embonini yezemithi, isetshenziselwa ikakhulukazi ukuhlanganiswa kwama-polypeptide ahlukahlukene, esikhundleni somuthi we-L-Tryptophan peptide wokwandisa isigamu sempilo nokunciphisa imiphumela emibi, kodwa ngeke imelane nomzimba wangaphambili, futhi izoba i-enzyme inhibitor ebalulekile. .Kungase futhi ngcono amasosha omzimba, ukubambezeleka ukungezwani komzimba.Imithi elwa namagciwane ye-peptide ingamelana namagciwane e-gram-positive, amagciwane e-Gram-negative namanye, njenge-Pseudomonas aeruginosa, i-mycobacteria, isikhunta, amagciwane, amagciwane namaseli e-tumor, avimbela kangcono futhi abulale ikhono.
I-D-Tryptophan ingasetshenziselwa ukwenziwa kwemithi elwa namagciwane eyi-semi-synthetic, lapho i-pharmacological idlala indima ebalulekile kuchungechunge oluseceleni.Isibopho se-peptide sinzima ukuba sibe yisenzo se-enzyme ye-β-lactam, ngakho-ke ukuzinza okuphezulu, futhi kune-spectrum ebanzi ye-antibacterial, ubuthi, i-hypoallergenic, ukumuncwa okusheshayo, ukugxila okuphezulu kwegazi komuthi isikhathi eside.
