Characterization Of Novel Cannabinoid Receptor 2-Selective Agonists At The Biochemical And Cellular Levels: Leads For Therapeutic Agents, Ashley M. Hine

Honors Scholar Theses

Putative cannabinoid receptor 2 (CB₂)-selective agonists were identified from a library of commercially available compounds via inhibition of cAMP accumulation in high throughput screening. Binding affinity and receptor subtype selectivity were assessed using heterologous competition binding assays against the known cannabinoid orthosteric ligand CP55940. Test compounds ASX0152383 and CSC003141 preferentially bound to CB₂, with no detection of binding to CB₁ up to 1 mM. CMB038865 exhibited nearly 100-fold selectivity for CB₁ over CB₂, while CZ000026 bound non-preferentially to both receptors in the low micromolar range. To determine the extent of G protein …
