Six Ugi-based designs. First three target the backbone carbonyl oxygen of T26 with hydrogen bond donors. Second three aim to reduce lipophilicity of P2 substituent.
The pdb file associated with the submission contains the following structures: (1) Edited version of 6w63 pdb protein stucture (2) Ligand from 6w63 pdb structure (3) Ligand from x2572 (one of the t-Bu methyls is replaced by nitrile in the 6th design) (4-9) Designs 1-6. The fluorophenethyl substituent of each design has been truncated to methyl for the structure models. I will provide additional information as a comment on the submission.
