Synthetic Marine Sponge Collagen by Late-Stage Dihydroxylation

Synthetic Marine Sponge Collagen by Late-Stage Dihydroxylation

Based on the observation that an increased substrate size is paralleled by an enhanced diastereoselectivity, a late-stage dihydroxylation protocol toward the 21mer CMP (collagen model peptide) Ac-(Pro-Hyp-Gly)3-Pro-Dyp-Gly-(Pro-Hyp-Gly)3-NH2 is presented. C3 and C4 hydroxylation have a converse effe...

description Based on the observation that an increased substrate size is paralleled by an enhanced diastereoselectivity, a late-stage dihydroxylation protocol toward the 21mer CMP (collagen model peptide) Ac-(Pro-Hyp-Gly)3-Pro-Dyp-Gly-(Pro-Hyp-Gly)3-NH2 is presented. C3 and C4 hydroxylation have a converse effect on the triple-helical stability of collagen. Their combined influence on the melting temperature was studied by NMR spectroscopy.
