N-(p-amylcinnamoyl) anthranilic acid is primarily used in biochemical research as a potent and selective inhibitor of calcium-dependent chloride channels. These channels play a critical role in various physiological processes, including fluid secretion and smooth muscle contraction. By inhibiting these channels, this compound helps researchers study their function and regulation in cellular and tissue systems. It is particularly valuable in investigating diseases related to chloride channel dysfunction, such as cystic fibrosis and certain types of hypertension. Additionally, it serves as a tool in pharmacological studies to explore potential therapeutic interventions targeting chloride channel activity.
