Stage #1: With N-ethyl-N,N-diisopropylamine In N,N-dimethyl-formamide at 24 – 32℃; for 5h; Stage #2: With piperidine In N,N-dimethyl-formamide for 0.25h; Further stages; Experimental Procedure 1 1-1. Resin Swelling General procedure: A solid-phase synthesis reactor equipped with a filtration membrane was used.Peptide synthesis having a carboxyl group (-COOH) at the end of the complex was used with 2-chlorotrityl chloride resin (Bead Tech, Korea),Peptide synthesis was terminated with a peptide bond (-CONH2) at the end of the complex using a link amide resin (GLS, China).Resin was swollen for 20 minutes using dichloromethane and dimethylformamide to prepare the preparation.1-2. Amino acid loadingSynthesis with chlorotrityl chloride resin involves loading the first amino acid into the resin.The resin was removed solvent through a filtration membrane under reduced pressure.3 to 5 equivalents of the amino acid in the resin was completely dissolved in DMF and added to chlorotrityl chloride resin,In consideration of density, diisopropylethylamine was added in an amount corresponding to 3-5 equivalents of chlorotrityl chloride resin.Thereafter, the reaction was performed at 24 ° C. to 32 ° C. for at least 5 hours using a reactor. 1-3. Resin Fmoc DeprotectionSynthesis using the chlorotrityl chloride resin or linkamide resin included a process of deprotection of Fluorenylmethyloxycarbonyl chloride (Fmoc).Resin Fmoc deprotection process removes solvent through the membrane under reduced pressure,After washing for 5 minutes with DMF added 20% (v / v) piperidine, and then again for 10 minutes. The reaction solution was removed by filtration under reduced pressure, and washed six more times for five minutes using DCM or DMF. 1-4. Fatty acid-amino acid complexes and fatty acid- oligopeptide complexes synthesis3 to 5 equivalents of the amino acid in the link amide resin was completely dissolved in DMF, and the solvent was removed to the link amide resin.As a coupling reagent, 2 M HOBt / DIC (hydroxybenzotriazole / diisopropylcarbodiimide) was added to the amino acid equivalent and the link amide resin amount.Then, the synthesis was carried out at 24 ~ 32 5 hours or more using a reactor.After the reaction was completed, the solvent was removed through a filtration membrane under reduced pressure,Washed six times with clean DMF five times.After washing, the amino acids were coupled in sequence in the same manner as the amino acid binding method.Thereafter, 3 equivalents of fatty acid was added to the resin in the state where the peptide was synthesized.2 M HOBt / DIC was added according to amino acid equivalent and resin amount.After using the reactor for 5 hours or more, it was reacted at a temperature of 24 ~ 32 . 1-5. CleavageAfter the reaction was completed, the solvent was removed through the filtration membrane under reduced pressure twice with clean DMF twice for 2 minutes,After washing twice with DCM twice, the solvent was almost removed through the filtration membrane under reduced pressure.The dried peptide complex resin was separated for 4 hours using 70% (v / v) TFA / 29% (v / v) DCM / 1% (v / v) H2O solution.1-6. CrystallizeThe separated solvent was extracted by recrystallization of the crude product using ethyl ether. |
