合成路线1
The compound was prepared via solid-phase synthesis using Rink-amide resin (I). After initial Fmoc-deprotection of (I) with piperidine in DMF, Fmoc-L-phenylalanine (II) was coupled to the resin by means of N,N'-diisopropyl carbodiimide (DIC) and hydroxybenzotriazole (HOBt) in DMF, yielding the phenylalanine-linked resin (III). Subsequent Fmoc-deprotection and coupling cycles with protected arginine (IV) and cyclohexylalanine (VI) produced the peptide resins (V) and (VII), respectively. Further deprotection of (VII) with piperidine, followed by coupling with 5-bromonicotinic acid (VIII) gave the corresponding amide (IX). Cleavage of the final peptide amide from the resin (IX) was then accomplished by treatment trifluoroacetic acid and anisole.
