Organocatalysts of oxidative protein folding inspired by protein disulfide isomerase

Organocatalysts derived from diethylenetriamine effect the rapid isomerization of non-native protein disulfide bonds to native ones. These catalysts contain a pendant hydrophobic moiety to encourage interaction with the non-native state, and two thiol groups with low pKa values that form a disulfide bond with a high E°' value.
