YieldReaction ConditionsOperation in experiment
SPPS method B refers to the synthesis of a protected peptidyl resin using Fmoc chemistry on a microwave based Liberty peptide synthesiser (CEM Corp., North Carolina). A suitable resin is a pre-loaded, low-load Wang resinavailable from Novabiochem (e.g. low load Fmoc-Lys(Mtt)-Wang resin, 0.35 mmol/g). Fmoc-deprotection was with 5percentpiperidine in NMP at up to 70 or 75°C. The coupling chemistry was DIC/HOAt in NMP. Amino acid/HOAt solutions (0.3M in NMP at a molar excess of 3-10 fold) were added to the resin followed by the same molar equivalent of DIC (0.75Min NMP). For example, the following amounts of 0.3M amino acid/HOAt solution were used per coupling for the followingscale reactions: Scale/ml, 0.10 mmol/2.5 ml, 0.25 mmol/5 ml, 1 mmol/15 ml. Coupling times and temperatures weregenerally 5 minutes at up to 70 or 75°C. Longer coupling times were used for larger scale reactions, for example 10min. Histidine amino acids were double coupled at 50°C, or quadruple coupled if the previous amino acid was stericallyhindered (e.g. Aib). Arginine amino acids were coupled at RT for 25 min then heated to 70 or 75°C for 5 min. Someamino acids such as but not limited to Aib, were "double coupled", meaning that after the first coupling (e.g. 5 min at75°C), the resin is drained and more reagents are added (amino acid, HOAt and DIC), and the mixture in heated again(e.g. 5 min at 75°C). When a chemical modification of a lysine side chain was desired, the lysine was incorporated asLys(Mtt). The Mtt group was removed by washing the resin with DCM and suspending the resin in neat (undiluted)hexafluoroisopropanol for 20 minutes followed by washing with DCM and NMP. The chemical modification of the lysinewas performed either by manual synthesis (see SPPS method D) or by one or more automated steps on the Libertypeptide synthesiser as described above, using suitably protected building blocks (see General methods), optionallyincluding a manual coupling. Preparation: SPPS method B, starting with low-load Fmoc-Lys(Mtt)-Wang resin. Fmoc-Lys(Mtt)-OH was usedin position 26, and Boc-His(trt)-OH was used in position 7. The Mtt was removed with HFIP manually, and 8-(9-fluorenylmethyloxycarbonyl-amino)-3,6-dioxaoctanoic acid (commercially available from Iris Biotech), Fmoc-Glu-OtBu andtetradecanedioc were coupled using a double coupling method on the Liberty Peptide synthesiser. The theoreticalmolecular mass was confirmed by MALDI-MS.UPLC (method 08_B4_1): Rt = 8.6 minUPLC (method 04_A3_1): Rt = 9.7 minMALDI-MS: 4788
