GPR55 Activators

GPR55 Activators encompass a range of chemical compounds that distinctly enhance the functional activity of GPR55, a G protein-coupled receptor involved in various cellular signaling pathways. O-1602 and Abnormal cannabidiol are synthetic analogs of natural cannabinoids, acting as selective GPR55 agonists. Their binding to GPR55 catalyzes the activation of phospholipase C and the β-arrestin pathway, respectively, leading to calcium mobilization and receptor internalization processes vital for cellular responses. Lysophosphatidylinositol, an endogenous ligand, and CID16020046, a synthetic compound, both amplify GPR55 signaling through the activation of Gq-mediated pathways and ERK phosphorylation, promoting cellular proliferation and differentiation. Similarly, compounds like ML184, ML185, and ML192 selectively bind to GPR55, enhancing MAPK and AKT pathway activities, crucial for cell survival and metabolic regulation. The controversial role of Cannabidiol (CBD) in modulating GPR55 activity, potentially influencing calcium and MAPK signaling, adds another dimension to the understanding of GPR55 modulation.Additionally, inverse agonists like AM251 and SR141716A, known for their primary actions on CB1 receptors, also interact with GPR55. These compounds can inhibit GPR55's constitutive activity, leading to an indirect enhancement of specific GPR55-mediated signaling under overactive receptor conditions. GSK494581A and VPC 23019, although less conventional in their roles, contribute to the modulation of GPR55's function. GSK494581A activates G protein-mediated pathways, while VPC 23019, despite being an S1P receptor antagonist, may influence GPR55-mediated pathways, particularly those related to cellular migration and immune response. These diverse GPR55 activators, through their targeted effects on specific signaling pathways, collectively contribute to the nuanced regulation and enhancement of GPR55's functional role in various physiological processes.
