TL;DR: In this article, the authors present compounds that form covalent bonds with Bruton's tyrosine kinase (BTK) for the treatment of autoimmune diseases or conditions.
Journal ArticleDOI
Synthesis and biological evaluation of substituted benzoxazoles as inhibitors of mPGES-1: use of a conformation-based hypothesis to facilitate compound design.
Daniel P. Walker,Graciela B. Arhancet,Hwang-Fun Lu,Steven E. Heasley,Sue Metz,Natasha M. Kablaoui,Francisco M. Franco,Hanau Cathleen E,Jeffrey A. Scholten,John Robert Springer,Yvette M. Fobian,Jeffrey S. Carter,Li Xing,Shengtian Yang,Alexander F. Shaffer,Gina M. Jerome,Michael T. Baratta,William M. Moore,Michael L. Vazquez +18 more
TL;DR: The design, synthesis, mPGES-1 activity and in vivo PK of a novel set of substituted benzoxazoles are described and a conformation-based hypothesis for mPGE(2) synthase1 activity based on the preferred conformation of the cyclohexane ring within this class of inhibitors is described.
