Publication Abstract from PubMed

An X-ray crystal structure of one of our previously discovered RORgammat inverse agonists bound to the RORgammat ligand binding domain revealed that the cyclohexane carboxylic acid group of compound 2 plays a significant role in RORgammat binding, forming four hydrogen bonding and ionic interactions with RORgammat. SAR studies centered around the cyclohexane carboxylic acid group led to identification of several structurally diverse and more potent compounds, including new carboxylic acid analogues 7 and 20, and cyclic sulfone analogues 34 and 37. Notably, compounds 7 and 20 were found to maintain the desirable pharmacokinetic profile of 2.
