| In vitro | A molecule AK778 and its cleavage product Col003 competitively inhibited the interaction and caused the inhibition of collagen secretion by destabilizing the collagen triple helix. Structural information obtained with NMR analysis revealed that Col003 competitively binds to the collagen-binding site on Hsp47. Col003 has an inhibitory effect on the interaction of Hsp47 with collagen in Hsp47 KO / MEFs. Col003 (0.01-100 μM) exhibits dose-dependent effects on the interactions of Hsp47 with collagen (IC50: 1.8 μM for Hsp47). Col003 (100 μM; 20-60 mins) has an inhibitory effect on collagen secretion and accumulation. It inhibits collagen secretion by wild-type MEFs and the secretion is not abolished completely. Col003 (100 μM) degrades α,α′-dipyridyl collagen secretion completely by incubation with trypsin at a high temperature (50 °C for 15 min), but is resistant to trypsin digestion at 37 °C. |
