October 2022 "Study of small molecule binding to live cells provides important information on the characterization of ligands pharmacologically. Here we developed and validated a label-free, liquid chromatography-mass spectrometry (LC-MS) based cell binding assay, using centrifugation to separate binders from non-binders. This assay was applied to various target classes, with particular emphasis on those for which protein-based binding assay can be difficult to achieve. In one example, to study a G protein coupled receptor (GPCR), we used one antagonist as probe and multiple other antagonists as competitor ligands. Binding of the probe was confirmed to be specific and saturable, reaching a fast equilibrium. Competition binding analysis by titration of five known ligands suggested a good correlation with their inhibition potency. In another example, this assay was applied to an ion channel target with its agonists, of which the determined binding affinity was consistent with functional assays. This versatile method allows quantitative characterization of ligand binding to cell surface expressed targets in a physiologically relevant environment."

In this study, we report the discovery of a novel lead compound for S1R binding, based on the thiazolidine Six compounds showed more than 50% displacement of the radioligand at 10 µM concentration with compound Moreover, compounds 6c and 6e showed a significant selectivity over S2R. In addition, molecular docking predicted that all the compounds showed the critical salt bridge with Upon optimization, this series of compounds could represent potential clinically useful S1R ligands for

Chemical libraries containing fragment- (1.6 million molecules) and lead-like (4.6 million molecules) compounds Among the top-ranked compounds, 59 fragments and 59 lead-like compounds were selected for experimental Of these, four fragment- and seven lead-like compounds were confirmed to bind to the allosteric site The four compounds with the highest affinities were demonstrated to be negative allosteric modulators

The results were striking: AlphaFold2 outperformed homology models, achieving a 60% hit rate for compounds AlphaFold3, the latest version, has improved on this by modeling interactions with various compounds, in modeling interactions with natural ligands but struggles to generalize this accuracy to synthetic compounds

Systematic modification of 1 was performed to produce compounds with improved potency and ADME properties Orally bioavailable compound 47 with favorable agonist potency (Ca2+EC50 = 24 nM, cAMPi EC50 = 6.5 nM This compound has vastly reduced brain penetration and is devoid of significant off-target liability.

The highest affinity compounds (15 to 24 nM) were identified from AF2 docking. Functional activity of selected compounds was assessed across 5-HT2A, 5-HT2B, and 5-HT2C receptors, with several compounds demonstrating subtype selectivity and high potency, some with sub-nanomolar EC50 values

Out of 35 tested compounds, 4 compounds were active in CHO-K1 cells expressing the human β3 -AR, and 8 compounds were active in CHO-K1 cells expressing the mouse β3 -AR."
