SQ 22536 is primarily used in research settings as a selective inhibitor of adenylate cyclase, an enzyme involved in the production of cyclic AMP (cAMP). By inhibiting this enzyme, SQ 22536 helps scientists study the role of cAMP in various cellular processes, including signal transduction and regulation of physiological functions. It is particularly valuable in investigating pathways related to G-protein-coupled receptors (GPCRs) and their downstream effects. This compound is also utilized in studies focusing on cardiovascular, neurological, and metabolic systems to better understand the mechanisms underlying diseases and potential therapeutic targets. Its application aids in elucidating the complex interplay of cellular signaling and its impact on health and disease.
