Journal ArticleDOI
Selective cyclooxygenase-2 inhibitors: heteroaryl modified 1,2-diarylimidazoles are potent, orally active antiinflammatory agents.
Ish Kumar Khanna,Yi Yu,Rita M. Huff,Richard Weier,Xiangdong Xu,Koszyk Francis,P. W. Collins,J. N. Cogburn,Peter C. Isakson,C. M. Koboldt,J. Masferrer,W. E. Perkins,Karen Seibert,A. W. Veenhuizen,Jing Yuan,D.-C. Yang,Yan Zhang +16 more
TL;DR: A series of heteroaryl modified 1,2-diarylimidazoles has been synthesized and found to be potent and highly selective (1000−9000-fold) inhibitors of the human COX-2 as discussed by the authors.
Journal ArticleDOI

Matthew J. Graneto,Ravi G. Kurumbail,Michael L. Vazquez,Huey-Sheng Shieh,Jennifer L. Pawlitz,Jennifer M. Williams,William C. Stallings,Lifeng Geng,Ashok S. Naraian,Koszyk Francis,Michael A. Stealey,Xiangdong D. Xu,Richard Weier,Gunnar J. Hanson,Robert J. Mourey,Robert P. Compton,Stephen J. Mnich,Gary D. Anderson,Joseph B. Monahan,Rajesh V. Devraj +19 more
TL;DR: A series of pyrazole inhibitors of p38 mitogen-activated protein (MAP) kinase were designed using a binding model based on the crystal structure of 1 (SC-102) bound to p38 enzyme, and a compound identified from this series was efficacious in an animal model of rheumatic disease.
Journal ArticleDOI
