Chủ đề: Advancing allosteric modulation to target the Adenosine A1 Receptor


The adenosine A1 G protein-coupled receptor (A1R) is an attractive therapeutic target for a range of cardiovascular and neuronal disorders. However, it remains sub-optimally targeted due to high doses and the lack of highly subtype-selective ligands causing adverse effects (such as bradycardia, atrioventricular block, and hypotension). Emerging paradigms of A1R pharmacology, including allostery and biased agonism, offer considerable clinical potential, presenting the opportunity to develop potent therapeutics with minimal on-target side effects. My research aims to understand the structural basis and the mechanism of allosteric modulation and biased agonism at the A1R and to develop a computational approach to identify novel A1R ligands. We have used a combined approach of mutagenesis, analytical pharmacology and molecular modelling (docking and molecular dynamics simulation) to identify molecular determinants of orthosteric ligand binding and activation, as well as allosteric modulation at the A1R. Subsequent structure-function studies validated the first high-resolution A1R structures in the inactive, active, allosteric modulator bound, and biased agonist bound conformations. Employing a high-throughput screening approach, we have elucidated the structure-activity relationship of a series of A1R-biased agonists, identifying a high potency A1R-biased agonist. We recently had three successful structure-based virtual ligand screening campaigns for novel orthosteric and allosteric ligands targeting A1R. Specifically, we discovered first-in-class A1R allosteric inhibitors, novel high-affinity A1R antagonists, and novel A1R allosteric enhancers. Currently, we are incorporating artificial intelligence deep learning models to assist our A1R drug discovery pipeline. Collectively, findings from my research will assist in overcoming the challenges associated with the discovery, validation, and development of novel A1R therapeutics with improved clinical efficacy for the treatment of major global health burdens.
