Abstract
CXCR4 is a GPCR involved in leukocyte trafficking. Small molecule antagonists of the receptor may treat inflammatory disease, cancer and HIV. Here we probe the binding of a tetrahydroisoquinoline-based antagonist (TIQ-10) to CXCR4 using saturation transfer double-difference (STDD) NMR. STDD spectra were acquired using extracts from Chinese Hamster Ovary cells expressing membrane-embedded CXCR4. The experiments demonstrate competitive binding between TIQ-10 and established antagonists and provide the TIQ-10 - CXCR4 binding epitope. Molecular modeling of TIQ-10 into the binding pocket provides a pose consistent with STDD-derived interactions. This study paves the way for future investigations of GPCR-ligand interactions in a biological milieu for use in chemical biology, biochemistry, structural biology, and rational drug design.

Abstract
Fragment screening by saturation transfer difference nuclear magnetic resonance (STD-NMR) is a robust method for identifying small molecule binders and is well suited to a broad set of biological targets. STD-NMR is exquisitely sensitive for detecting weakly binding compounds (a common characteristic of...
