G-protein-coupled receptors (GPCRs) are important therapeutic targets and numerous approved drugs act by either stimulating or blocking receptor activation. However, the design of ligands that modulate GPCR signaling is challenging. We demonstrate that molecular simulations of GPCRs can be used to predict ligand efficacy and identify potent β2-adrenoceptor agonists.
Efficient Multikilogram-Scale Synthesis of PTDSS1 Inhibitor: Development of a Practical and Scalable Optical Resolution Method for Chiral 2,3-Pyrrolidinedione
selective phosphatidylserine synthase 1 (PTDSS1) inhibitor discovered by Daiichi Sankyo. We have developed a practical and unique optical resolution method using a chiral amine for 2,3-pyrrolidinedione, enabling the large-scale synthesis of the active pharmaceutical ingredient with high enantiomeric excess. Through optimization of the entire synthesis method from the perspective of process chemistry
