YieldReaction ConditionsOperation in experiment
HMPB-BHA resin (5.00 g, substitution level = 0.80 mmol/g) was placed in a 200 mL Advanced ChemTech reaction vessel and swollen by washing with DMF (3 x 50 mL). A solution of Fmoc-Hphe-OH (4.85 g, 12.1 mmol) in DMF (50.0 mL) was added to the vessel and the mixture shaken for 0.25 hours. Pyridine (1.62 mL, 20.0 mmol) followed by 2,6-dichlorobenzoyl chloride (1.72 mL, 12.0 mmol) in DMF (50.0 mL) were added and the mixture shaken for 8 hours at 22 C. The resin was washed with DMF, CH2Cl2, methanol, CH2Cl2 and DMF (3 x 90 mL each) then treated with DMF (50.0 mL), pyridine (1.62 mL, 20.0 mmol) and benzoyl chloride (1.40 mL, 12.1 mmol) and the vessel shaken for 3 hours. Final washing was then performed with DMF, CH2Cl2, methanol and CH2Cl2 (3 x 50 mL each) and the loading (0.60 mmol/g) determined by fulvene-piperidine assay.

YieldReaction ConditionsOperation in experiment
Fmoc-Leu-HMPB BHA resin (4.37 g, substitution level = 0.51 mmol/g) was placed in a 200 ml Advanced ChemTech reaction vessel. The resin was swollen by washing with DMF (2 x 50 mL), and the following steps were performed: (Step 1) The Fmoc group was removed upon exposure to a solution of piperidine in DMF (1 :4 v/v, 50 mL) for 0.5 hours. (Step 2) The resin washed with DMF, CH2Cl2, methanol, CH2Cl2 and DMF (3 x 50 mL each). (Step 3) A solution of Fmoc-Hphe-OH (2.68 g, 6.69 mmol), HOBt (1.02 g, 6.69 mmol), HBTU (2.54 g, 6.69 mmol) and Z-Pr2NEt (3.88 mL, 22.3 mmol) in DMF (50.0 mL) was added to the resin and the reaction vessel shaken 4 hours. (Step 4) The resin washed with DMF, CH2Cl2, methanol, CH2Cl2 and DMF (3 x 50 mL each). (Step 5) The coupling reaction was found to be more than 95% complete as assessed by the fulvene-piperidine assay. Steps 1-5 were repeated with Fmoc-NLys(Boc)-OH, Fmoc-Leu-OH and Fmoc-Pro-OH respectively, to complete the sequence PL-NLys(Boc)~Hphe-Leu

Peptide 5 was synthesised using conventional solid phase peptide synthesis, using an Fmoc-based strategy. Commercially-available Fmoc-Tyr-OH immobilised on a Wang resin was utilised. Synthesis of peptide acids was achieved manually. The resin was swelled thoroughly in DMF, followed by removal of the N-Fmoc protecting group by treatment with 20% v/v piperidine in DMF (3 x 3 min). All subsequent couplings were performed in DMF, employing 2.5-fold molar excesses of N-Fmoc protected amino acids (with appropriate side-chain protecting groups), and activated using HCTU/HOBt/DiPEA. N-Fmoc de-protections were performed using 20% piperidine in DMF (3 x 3 min). The success of couplings and de-protections was monitored using the ninhydrin-based Kaiser test. Unsuccessful couplings were repeated. After the final N-Fmoc deprotection, the peptide chain was endcapped with fluorescein isothiocyanate (2.50 eq, in the presence of DiPEA, 1.50 eq). The success of this reaction was also monitored by the Kaiser test. An additional beta-alanine residue was incorporated into the sequence to overcome incompatability of the thiourea linkage and the acidic conditions of cleavage (the thiourea can rearrange, and the carbonyl carbon of the preceding amide bond can undergo nucleophilic attack by the sulphydryl-like function so formed. This leads to cleavage of the amide bond, with concomitant formation of a cyclic thiazolinone. The thiazolinone can undergo rearrangement in the presence of aqueous acid to form a thiohydantoin). On completion of the sequence, the resin was washed and dried in vacuo over KOH to constant weight. Peptides were cleaved from the resin by mild acidolysis using trifluoroacetic acid (TFA):H20:triisopropylsilane 95:2.5:2.5 for 4 h at room temperature, with simultaneous side-chain de-protection. Following cleavage, the TFA was removed under reduced pressure. The crude product was extracted into 95% aqueous acetic acid and lyophilised. The crude peptide was subsequently analysed using reversed phase HPLC and purified using preparative HPLC (purity >97%). Pure fractions were combined and lyophilised. Identity was confirmed by mass spectrometry.
