Design Rationale:

The submission consists of 9 designs based on a 6-membered cyclic sulfone scaffold that are intended to address the issue of isoquinoline metabolism. I currently consider the 1-methylpyrazolopyridine to be the isoquinoline replacement (Design 1; see submission notes for PET-UNK-e274cad4) with the most potential to reduce metabolism with minimal loss of affinity and I’ve also included two methoxynaphthyridines (Designs 2 and 3; see submission notes for PET-UNK-f4e47ebd). The 7-fluoro, 6-fluoro and 6,7-difluoro isoquinolines have been included as Designs 5-7 (I consider Design 5 to be of a higher priority than Designs 6 or 7).

Other Notes:

Protein-ligand complexes (X11612 A chain) were energy minimized using Szybki (MMFF94S; amide carbonyl O and isoquinoline N fixed at the positions of the crystallographic ligand). The PDB file associated with this submission contains the following: [1] X11612 A chain from complex with Design 3 [2] X11612 A chain crystallographic ligand (MAT-POS-b3e365b9-1) [3-11] Designs 1-9.
