Uphando lweBiyochemical:
Kwi-peptide synthesis, i-H-Asp (OBzl) -NCA isebenza njengento ebalulekileyo yokwakha i-synthesis yamatyathanga e-peptide aqukethe ukulandelelana kwe-aspartic acid.
Iqela layo le-benzyl ester lisebenza njengeqela elikhuselayo, livumela ukuqaliswa kokuguqulwa kweekhemikhali ezithile ngexesha le-peptide chain synthesis, enokuthi emva koko isuswe phantsi kweemeko ezifanelekileyo ukufumana ulandelelwano olufunwayo lwe-aspartic acid.
Kwizifundo zokuguqulwa kweprotheyini okanye i-peptide, i-H-Asp (OBzl) -NCA ingasetyenziselwa ukwazisa ukuguqulwa kweekhemikhali ezithile ukuphanda indlela ezi nguqulelo zichaphazela ngayo umsebenzi webhayoloji okanye ukusebenzisana kunye nezinye iimolekyuli zeprotheni okanye i-peptide.
Ukufunyanwa kweziyobisi:
I-H-Asp(OBzl)-NCA inokusebenza njenge-precursor yokwenziwa okanye i-intermediate yeemolekyuli zamachiza, evumela ukuqaliswa kwezakhiwo zeekhemikhali ezithile ngexesha loyilo lwamachiza ukufumana abaviwa beziyobisi kunye nemisebenzi ye-biological.
Ngokusabela namanye amaqhekeza amachiza okanye iimolekyuli zebhayoloji esebenzayo, inokuququzelela ukuhlanganiswa kwamachiza asekwe kwipeptide okanye iikhompawundi ze-heterocyclic ezineziphumo ezithile zonyango.
Kwiinkqubo zokufumanisa iziyobisi, i-H-Asp(OBzl)-NCA ingasetyenziselwa ukuhlolwa kwe-high-throughput screening kunye nokuvavanya umsebenzi we-biological ukuvavanya imisebenzi yokulandelelana kwe-peptide eyahlukeneyo okanye abaviwa beziyobisi.
Umzi mveliso wamachiza:
Kwishishini lamachiza, i-H-Asp(OBzl)-NCA isebenza njengento ekrwada okanye ephakathi kwimveliso yeziyobisi zepeptide ezisebenzayo.
Ngokusabela kokujiya kunye nezinye ii-amino acids okanye amaqhekeza eziyobisi, inokuququzelela ukuhlanganiswa kwamachiza e-peptide kunye nemisebenzi ethile yebhayoloji, efana ne-antibiotics, iihomoni, i-enzyme inhibitors, nokunye.
Iqela le-benzyl ester elikhoyo kwisakhiwo salo likhusela i-carboxylic acid ye-aspartic acid, igalelo ekuzinzeni nasekusebenzeni kwakhona kwekhonkco le-peptide ngexesha lokudibanisa.
