4 Resins for Solid Phase Peptide Synthesis 4

5 Core resin Polystyrene is the most common core resin in solid phase chemistry: - High swelling in apolar solvents - Chemically stable Swelling factor of 1% crosslinked polystyrene in various solvents (ml/g of resin) Solvent Swelling (ml/g) Solvent Swelling (ml/g) THF 5.5 Et 2 O 3.2 Toluene 5.3 CH 2 CN 4.7 CH 2 Cl EtOH 5.0 Dioxane 4.9 MeOH 1.8 DMF 3.5 Water 1.0 (no swelling) 5

6 Chloromethyl Resin (Merrifield Resin) Particle size: mesh ( micron) Loading: mmol/g (after coupling with AA mmol/g) Advantages and use: - Substrates are attached to Merrifield resin by nucleophilic displacement of chlorine - Resin-substrate bond is acid stable and requires strong acid conditions for cleavage - Useful for SPPS and different applications as scavenger resins and polymer-supported reagents 6

7 Aminomethyl Resin (AM Resin) Particle size: mesh ( micron) Loading: mmol/g (after coupling with AA mmol/g) Advantages and use: - Aminomethyl (AM) resin has long been used in solid phase peptide synthesis as a core resin - various linkers can be attached through a stable amide bond 7

8 2-Chlorotrityl Chloride Resin (2-CTC) Particle size: mesh ( micron) Loading: mmol/g (after coupling with AA mmol/g) Advantages and use: - widely used in both solid phase organic and peptide chemistry - cleaved with acetic acid - particularly useful when less acid labile protecting groups are required on the substrate following cleavage - Bulky triphenylmethyl group prevents cyclization or racemization through steric hindrance - used to immobilize acids, alcohols and also amines or thiols - 2-chlorotrityl resin has better stability than the trityl resin 8

9 4-Benzyloxybenzyl Alcohol Resin (Wang resin) Particle size: mesh ( micron) Loading: mmol/g (after coupling with AA mmol/g) Advantages and use: - most widely used solid phase support for acid substrates - linker attached to the polystyrene core is 4-hydroxybenzyl alcohol - linkage has good stability to a variety of reaction conditions, but can be readily cleaved by moderate treatment with an acid, generally trifluoroacetic acid 9

10 4-Methylbenzhydrylamine Hydrochloride Salt Resin (MBHA Resin) Particle size: mesh ( micron) Loading: mmol/g (after coupling with AA mmol/g) Advantages and use: - originally developed for the formation of peptide amides using the Boc-N protection/tfa deprotection strategy - form very stable amide or amine linkages to either carboxylic or electrophilic alkyl substrates structurally similar to Rink - strong acid conditions are required to cleave substrates from these resins (hydrofluoric acid or trifluoromethanesulfonic acid (TFMSA)); therefore they are also used as base resins for anchoring linkers 10
