β1-integrin

Pyrintegrin, a β1-integrin agonist, promotes the survival of embryonic stem cells, can be used as a podocyte-protective agent, and enhances cell-extracellular matrix adhesion-mediated integrin signaling.

DIM-C-pPhOH (CDIM8) is a nur77 (NR4A1) antagonist,inhibits TGF-β induced cell migration of breast cancer cell lines,promotes ROS/endoplasmic reticulum stress and proapoptotic pathways in pancreatic cancer cell lines,mimics effects of Nur77 RNAi silencing.

MORF-627 is an orally active selective inhibitor of integrin αvβ6 (integrinαvβ6), with an IC50 of 9.2 nM as measured in a human serum ligand binding assay. It effectively inhibits αvβ6-mediated activation of TGF-β1 with an IC50 of 2.63 nM and suppresses SMAD2/3 phosphorylation, showing an IC50 of 8.3 nM. Additionally, MORF-627 ameliorates bleomycin-induced pulmonary fibrosis in mice.

Compound Rh2 (Anticancer agent 133) is a cytotoxic and antimetastatic agent that induces cell cycle arrest, apoptosis, and autophagy. Additionally, it suppresses cell metastasis through the inhibition of EGFR expression, which is mediated by FAK-regulated integrin β1 [1].

VnP-16 enhances bone formation by stimulating the differentiation and activity of osteoblasts via direct β1 integrin engagement, which subsequently activates FAK [1].

VnP-16, a synthetic peptide fragment mirroring amino acids 270-281 of vitronectin (a multifunctional glycoprotein involved in cell attachment, migration, and spreading), promotes attachment and spreading of isolated human osteogenic cells. This effect is reversible with β1 integrin siRNA knockdown when VnP-16 is applied at 9.1 µg/cm2 on cell plates. The compound enhances osteogenesis in human skin-derived mesenchymal precursors and MC3T3-E1 mouse calvarial osteoblast precursors. Furthermore, in vivo studies show VnP-16 mitigates IL-1α-induced bone loss, reduces calvarial osteoclast numbers in mice, increases bone mineral density, and lessens trabecular bone loss in a mouse model of ovariectomy-induced bone loss.

VSLRGDTRG is a synthetic peptide derived from the RGD motif in cadherin17 (CDH17) that binds to the α2β1 integrin, activating its signaling pathways. By promoting high-affinity conformational changes in β1 integrins through the RGD motif, VSLRGDTRG enhances cell adhesion and the phosphorylation of FAK and ERK1/2, thereby driving tumor proliferation and metastasis. This peptide is useful for research on cancers expressing CDH17, such as colorectal and pancreatic cancer.

VSLRGDTRG acetate is a synthetic peptide of the RGD motif from cadherin17 (CDH17), capable of binding to α2β1 integrin and activating its signaling pathways. It facilitates the high-affinity conformational change of β1 integrin via the RGD motif, enhancing cell adhesion and phosphorylation of FAK and ERK1/2, thereby promoting tumor proliferation and metastasis. VSLRGDTRG acetate is applicable in research on cancers expressing CDH17, such as colon and pancreatic cancers.
