TL;DR: In human, 2 was found to be highly labile at the exo-cyclic amide bond that links the tetrahydrobenzothiophene moiety to the central aniline ring, resulting in insufficient parent drug exposure, which informed the back-up program and discovery of improved inhibitors.

TL;DR: A series of novel tricyclic compounds that improved upon the druglike properties of previous chemical matter are devised that are highly potent, selective for Btk, metabolically stable, well tolerated, and efficacious in an animal model of arthritis.

TL;DR: SAR studies were focused on reducing metabolic cleavage of this amide, and resulted in the identification of several central aryl linker substituents that conferred improved stability and preclinical properties.
