α 1(i) collagen , human

This is a peptide inhibitor of collagen fibrillar matrix assembly.

Benzyl-α-GalNAc (O-glycosylation-IN-1) is an effective inhibitor of O-glycosylation used to reduce the levels of mucin on the cell surface; it can inhibit the synthesis of O-glycosylated mucin in a human pancreatic cancer cell model. Benzyl-α-GalNAc effectively inhibits the proliferation and activation of LX-2 cells and suppresses the expression of collagen I/III, making it suitable for studies on liver fibrosis. Benzyl-α-GalNAc can be used in research on glycobiology, tumor metastasis, liver fibrosis, and chemotherapeutic sensitization.

ALK5-IN-82 is a potent and selective inhibitor of activin receptor-like kinase 5 (ALK5), demonstrating an IC50 value of 9.1 nM. This compound effectively suppresses the expression of α-smooth muscle actin (α-SMA), collagen I, and the proteinases tissue inhibitor of metalloproteinase 1 (TIMP-1) and matrix metalloproteinase 13 (MMP-13) in human umbilical vein endothelial cells induced by transforming growth factor-β. ALK5-IN-82 shows potential for use in research related to cardiac fibrosis.
