title: (+)-Cyanidanol-3 changes functional properties of collagen.
abstract: About 6-7 (+)-cyanidanol-3 molecules are bound per collagen alpha-chain. The (+)-cyanidanol-3 treated collagen contains an increased number of pepsin-resistant cross-links, is less susceptible to attack by mammalian collagenase, has a higher shrinkage temp and forms unstructured aggregates. Cell and organ culture studies show that these biological systems produce less protein and collagen in the presence of (+)-cyanidanol-3 and that the newly synthesized collagen is less soluble.
