  • PubMed Abstract: 

    A novel 5-phenylamino-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione series of MEK inhibitors has been developed using structure-based drug design. Lead optimization of this series led to the discovery of TAK-733. This was advanced to Phase I clinical studies for cancer treatment.
