Structure of RORgt bound to a tertiary alcohol
Structural highlights
FunctionRORG_HUMAN Possible nuclear receptor for hydroxycholesterols, the binding of which strongly promotes coactivators recruitment. Essential for thymopoiesis and the development of several secondary lymphoid tissues, including lymph nodes. Involved in lineage specification of uncommitted CD4(+) T-helper cells into Th17 cells. Regulate the expression of several components of the circadian clock. Publication Abstract from PubMedWe identified 6-substituted quinolines as modulators of the retinoic acid receptor-related orphan receptor gamma t (RORgammat). The synthesis of this class of RORgammat modulators is reported, and optimization of the substituents at the quinoline 6-position that produced compounds with high affinity for the receptor is detailed. This effort identified molecules that act as potent, full inverse agonists in a RORgammat-driven cell-based reporter assay. The X-ray crystal structures of two full inverse agonists from this chemical series bound to the RORgammat ligand binding domain are disclosed, and we highlight the interaction of a hydrogen-bond acceptor on the 6-position substituent of the inverse agonist with Glu379:NH as a conserved binding contact. 6-Substituted quinolines as RORgammat inverse agonists.,Barbay JK, Cummings MD, Abad M, Castro G, Kreutter KD, Kummer DA, Maharoof U, Milligan C, Nishimura R, Pierce J, Schalk-Hihi C, Spurlino J, Tanis VM, Urbanski M, Venkatesan H, Wang A, Woods C, Wolin R, Xue X, Edwards JP, Fourie AM, Leonard K Bioorg Med Chem Lett. 2017 Dec 1;27(23):5277-5283. doi:, 10.1016/j.bmcl.2017.10.027.
