摘要

A PDE4B over 4D-selective inhibitor programme was initiated to capitalise on the recently discovered predominance of the PDE4B subtype in inflammatory cell regulation. The SAR of a tetrahydrobenzothiophene (THBT) series did not agree with either of two proposed docking modes in the 4B binding site. A subsequent X-ray co-crystal structure determination revealed that the THBT ligand displaces the Gln-443 residue, invariably ligand-anchoring ...
