Screening of our internal compound collection for inhibitors of the transforming growth factor β1 (TGF-β1) type I receptor (ALK5) identified several hits. Optimization of the dihydropyrroloimidazole hit 2 by introduction of a 2-pyridine and 3,4-methylenedioxyphenyl group gave 7, a selective ALK5 inhibitor. With this information, optimization of the triarylimidazole hit 8 gave the selective inhibitor 14, which inhibits TGF-β1-induced fibronectin mRNA formation while displaying no measurable cytotoxicity in the 48 h XTT assay. |
