R-268712 is a potent and selective inhibitor of ALK5 with an IC50 of 2.5nM, an approximately 5000-fold more selectivity for ALK5 than p38 mitogen-activated protein kinase (MAPK). Oral administration of R-268712 at doses of 1, 3 and 10mg/kg also inhibited the development of renal fibrosis in a dose-dependent manner in a unilateral ureteral obstruction (UUO) model. R-268712 reduced proteinuria and glomerulosclerosis significantly with improvement of renal function. R-268712 could suppress glomerulonephritis as well as glomerulosclerosis by an inhibitory mechanism that involves suppression of TGF-β signaling.

| Pirfenidone
Pirfenidone (AMR69) is an antifibrotic agent that attenuates CCL2 and CCL12 production in fibrocyte cells. Pirfenidone inhibits TGF-β bioactivity by affecting TGF-β2 mRNA expression and processing of pro-TGF-β in CCL-64 cells. Pirfenidone (AMR69) attenuates CCL2 and CCL12 production in fibrocyte cells. |
