Solvent phase peptide synthesis
WebUncrosslinked, or linear, polystyrene will dissolve in hydrophobic solvents and precipitate in protic solvents. This property has been exploited by Janda in an interesting synthesis of prostaglandin F2α Most polystyrene supports used in solid phase chemistry, however, contain 1% or 2% divinylbenzene (DVB) as a crosslinking agent. WebSolid phase peptide synthesis requires large amounts of organic solvents, the safe disposal of which is an important environmental issue. Peptide synthesis, if performed in water and using less or nontoxic reagents, circumvents the disposal problem. Our ultimate aim is to develop an "environment-fri …
