MORF-627
MORF-627 is a highly selective, orally active integrin αvβ6 inhibitor. By blocking TGF-β1 activation and pSMAD2 signaling, MORF-627 significantly reduces collagen deposition, epithelial-mesenchymal transition markers, and structural changes in fibrotic cells. MORF-627 exhibits significant antifibrotic efficacy without genotoxicity in idiopathic pulmonary fibrosis models. However, MORF-627 induces bladder epithelial proliferation and early invasive urothelial carcinoma in cynomolgus monkeys and human cells, and this toxic effect can be reversed by exogenous TGF-β. MORF-627 can be used for studying the pathological mechanisms of pulmonary fibrosis and evaluating drug safety.

Biological Activity
|
αvβ6 1.1 nM (IC50) |
MORF-627 potently and selectively inhibits purified human integrin αvβ6 with an IC50 of 1.1 nM, exhibiting 450-fold and 300-fold selectivity over αvβ1 and αvβ8, respectively[1].
MORF-627 inhibits the binding of proTGF-β1 to HEK293 cells overexpressing human αvβ6, with an IC50 of 9.2 nM[1].
MORF-627 potently inhibits αvβ6-mediated TGF-β1 activation in a cell co-culture system, with an IC50 of 2.63 nM after 24 h of treatment[1].
MORF-627 inhibits the mRNA expression of ECM proteins in a co-culture system of primary fibroblasts and epithelial cells derived from human idiopathic pulmonary fibrosis (IPF)[1].
MORF-627 (0.01-3 μM; 3 d) induces dose-dependent proliferation of primary human bladder epithelial cells, while co-administration of 5 ng/mL exogenous TGF-β1 reverses this effect[3].
MORF-627 (0.01-3 μM; 3 d) induces dose-dependent proliferation of primary human alveolar epithelial cells within 3 days, and this effect is reversed by co-administration of 5 ng/mL exogenous TGF-β1[3].

MORF-627 (1-10 mg/kg; p.o.; twice daily; for 14 consecutive days) reduces fibrosis severity and collagen deposition in a bleomycin-induced chronic mouse model of pulmonary fibrosis[1].
MORF-627 induces epithelial proliferative changes in the bladder of 33% of tested cynomolgus macaques 28 days after administration[2].
MORF-627 (administered via gavage; daily; for consecutive 28 days at 30-180-120 mg/kg/day) induces dose-related proliferation of bladder epithelial cells; 33% of treated cynomolgus monkeys develop early invasive urothelial carcinoma, and the Ki67 proliferation index of urothelial cells is significantly increased in all dose groups[3].
