The two designs in this submission address potential metabolism at the P2 aromatic ring using structural modifications (RAL-THA-2d450e86-14 | RAL-THA-2d450e86-30) of the 3-chlorobenzyl known to be well tolerated. Sulfonylation of dihydroisquinoline nitrogen will render the carbonyl more electron-withdrawing and would be expected reduce metabolism at the P2 aromatic ring (greater metabolic stability of ALP-POS-c56c1477-3 relative to MAT-POS-e194df51-1 would point to metabolism at P2 as an issue). The racemic forms for the two designs are included the submission.
Protein-ligand complexes (P1788 A chain) were energy-minimized using Szybki (MMFF94S), fixing the coordinates the oxygen and nitrogen of the amide.
