G-protein-coupled receptors (GPCRs) are integral to various physiological functions in the human body. These receptors play a significant role in signaling pathways that mediate pharmacological responses. Notably, it is estimated that 30-50% of marketed drugs exert their effects by interacting with GPCRs, highlighting their importance as therapeutic targets across a wide array of diseases. The Importance of GPCR Assays in Drug DiscoveryWith the burgeoning field of drug discovery, high-throughput GPCR assays have become essential. These assays enable researchers to screen large libraries of compounds efficiently, facilitating the identification of novel drug candidates. The early phases of drug discovery often depend on functional GPCR assays that focus on G-protein-mediated second messenger signaling. However, contemporary advancements have broadened the scope of GPCR activities to include G-protein-independent pathways, yielding deeper insights into the functional selectivity of compounds. The integration of automated imaging systems and label-free detection technologies has further enhanced the suitability of these assays for high-throughput screening.
