Taupānga:

Ko te 1-(3-Dimethylaminopropyl)-3-Ethylcarbodiimide Hydrochloride (EDC·HCl) (CAS: 25952-53-8) he paura tioata ma, he ngawari te whakaheke, he memeha ki te wai, he wairewa i roto i te waihano, whakamahia hei tauhohenga whakahoaho mo te carboxyl. Ko nga roopu i roto i te amide synthesis, ka whakamahia ano mo te whakahohe i nga roopu phosphate, te honohono-whiti o nga pūmua me nga waikawa nucleic, me te hanga o nga immunocouplers.Ka whakamahia te EDC-HCl i roto i te awhe pH o 4.0-6.0 me te whakamahi i te nuinga o te waa me te N-Hydroxysuccinimide (NHS) me te N-Hydroxysulfosuccinimide konutai tote hei whakapai ake i te pai o te hono.
Ko te EDC·HCl he carbodiimide wairewa-wai, e whakamahia nuitia ana mo te hononga peptide.Ka whakamahia te EDC·HCl hei kaihoko whakakorikori carboxyl.He mahi nui mo te aukati i nga koiora nui i roto i te hononga ki te N-hydroxysuccinimide.Ka whakamahia ano ki te acylation o phosphoranes.
Ko te wai-wairewa o te carbodiimide e whai hua ana mo te whakakotahi i te haptens ki nga pūmua me nga polypeptides.Ka whakamahia ki te whakarereke i nga kaiwhakawhiwhi NMDA me te mea he maatete whakamaarama i roto i te whakahiato peptide.Ko te painga nui o te hononga EDAC he ngawari te tango i te reagent taikaha me te Urea e rite ana ma te horoi ki te waikawa waimeha, ki te wai ranei.Ko nga Carbodiimides ka whakakorikori i te hanganga o nga here amide, te waikawa carboxylic, me nga amine ma te whakahohe i te carboxylate ki te hanga i te O-acylurea.Ka taea e tenei takawaenga te whakaeke tika e te amine ki te hanga i te amide.Ka tukuna te EDAC hei pärönaki urea wairewa.
Ka taea te whakamahi EDC·HCl mo te whakahiato o nga amides.Ka whakamahia hei kaihoko hono i roto i te whakahiatotanga o nga esters mai i nga waikawa carboxylic ma te whakamahi i te dimethylaminopyridine hei whakakorikori.
Ko te nuinga o nga mea e toru e whakamahia nuitia ana i te toha: DCC, DIC me EDC·HCl.Ko te whakamahi i tenei momo o te maatete whakaahuru i te nuinga o te waa e hiahia ana ki te taapiri i nga whakakorikori acylation, nga kaiwhakaoho ranei, penei i te DMAP, HOBt, me etahi atu. karekau e whakamahia te catalyst ki te huri ki te ester hohe e rite ana, ki te amide kaha ranei, ka huri ano ki te hua-a-urea e rite ana ki te Urea (Ara B).Whakahohenga whakakorikori: Ko nga momo e whai ake nei o te kaiwhakaoho whakakorikori e whakamahia nuitia ana.I tenei wa, kua whakamahia nuitia te 4-N,N-dimethylpyridine (DMAP) ki te whakakoi i nga momo tauhohenga acylation.I etahi wa ka taea te whakamahi i te 4-PPY i te mea kaore i te pai te awe o te DMAP.E ai ki nga tuhinga e tika ana, ko tona kaha catalytic he tata ki te mano nga wa teitei ake i te DMAP.i roto i nga condenser e toru e whakamahia nuitia ana, he iti ake te DCC me te DIC.Ko te tikanga ka whakamahia tahi te DCC me te DMAP.Ko tetahi o nga ngoikoretanga nui o te whakamahi i te DCC ko tetahi atu hua o te tauhohenga, te dicyclohexylurea, he iti te whakarewatanga i roto i te waahanga kaiao whanui engari he iti te wairewa, na reira he uaua ki te tango tino ma roto i etahi tikanga purenga e whakamahia nuitia ana, recrystallization, tīwae chromatography, etc.;na te mea he iti te whakarewatanga o te dicyclohexylurea i roto i te ether i etahi atu whakarewa, no reira, ko te maimoatanga o tenei momo tauhohenga ka whakaeto i te whakarewa tauhohenga me te taapiri i te ether, me te tātari i te nuinga o te dicyclohexylurea i mua i etahi atu maimoatanga.Na te mea he pai ake te whakarewatanga o te diisopropylurea i hangaia e DIC i roto i nga whakarewa pararopi whanui, ka whakamahia i roto i te matū matū whakahiato-waahanga whakahiato.Kei te whakamahia te EDCI i tenei wa i roto i te matū rongoa.Ko tetahi o ona ahuatanga matua ko te Urea i hangaia i muri i te tauhohenga he wairewa-wai, he ngawari ki te horoi atu.Ko te tikanga, ka honoa te EDCI me te HOBt (whakatupato: he mea tino nui tenei tauhohenga HOBt, ki te kore he iti rawa te tukunga o te kondensation).I etahi wa mena he nui te aukati o te waikawa, he roopu tango irahiko ranei, ka noho te tauhohenga ki te hikoi ester hohe (he kaha te tohu awhiowhio a te ester kaha, ka kitea e MS, LC-MS ranei).
