5USQ - PubMed Abstract: 
A series of potent ALK5 inhibitors were designed using a SBDD approach and subsequently optimized to improve drug likeness. Starting with a 4-substituted quinoline screening hit, SAR was conducted using a ALK5 binding model to understand the binding site and optimize activity ...
