Isicelo:

I-DCC (N,N'-Dicyclohexylcarbodiimide, CAS: 538-75-0) isetshenziswa kukhemikhali ye-peptide njengento ehlanganisayo.Ikakhulukazi esetshenziselwa ukwakheka kokwenziwa kwama-peptides Ukufiphala kwama-amino acid.Isibonelo, ku-Fmoc-solid phase synthesis, iqembu le-carboxyl le-amino acid lakha isibopho se-amide neqembu le-amino lenye i-amino acid.Ukuze wenze iqembu le-carboxyl likwazi ukwamukela ukuhlaselwa kwama-nucleophiles, i-athomu ye-oksijini ekhokhiswe kabi idinga ukwenziwa isebenze ibe yiqembu elingcono elishiyayo, futhi i-DCC idlala le ndima.I-athomu ye-oxygen yeqembu le-carboxyl ku-amino acid isebenza njenge-nucleophile ukuhlasela i-athomu ye-carbon phakathi ne-molecule ye-DCC ukuze i-DCC ihlangane neqembu le-carboxyl yakhe isakhiwo se-ester, okwenza ukuhlasela kwe-nucleophilic kweqembu le-amino. kulula ukwenza i-coupling reagent.

I-DCC isetshenziselwa ukuhlanganiswa nokuqeda amanzi emzimbeni we-amikacin nama-amino acid.iyi-agent enhle yokushisa ephansi ye-biochemical dehydrating futhi isetshenziselwa ukuhlanganiswa kwama-acids, ama-anhydrides, ama-aldehydes, ama-ketones, njll. E-Japan, ama-dehydrating agents asetshenziselwa i-akhawunti ye-glutathione ye-90% yokusetshenziswa okuphelele.Uma umkhiqizo usetshenziswa njenge-ejenti yokuqeda amanzi emzimbeni kanye ne-condensing, ungasabela ngesikhathi esifushane ekamelweni lokushisa, futhi umkhiqizo ngemva kokusabela yi-dicyclohexylurea.Njengoba ukuncibilika komkhiqizo ku-solvent ye-organic kuncane kakhulu, umkhiqizo wokusabela kulula ukuwuhlukanisa;ngesikhathi esifanayo, ngoba umkhiqizo unzima ukuncibilika emanzini, ukusabela kusengaqhubeka ngisho nesisombululo esinamanzi.Umkhiqizo usetshenziselwa ukuhlanganiswa kwama-peptides nama-nucleic acid.Ukusetshenziswa kwalo mkhiqizo kungahlanganisa kalula ama-peptide avela kumakhompiyutha anamaqembu e-carboxyl yamahhala futhi ahlanganiswe namaqembu amahhala we-amino ekamelweni lokushisa, futhi isivuno siphezulu kakhulu.Isetshenziselwa ukukhiqizwa kwe-hypertensives kanye ne-cyclic adenosine monophosphate.esetshenziswa njenge-biochemical reagent kanye ne-organic synthesis dehydration condensing agent.
