Discovery and development of TRPV1 antagonists
Relief from chronic pain remains a recognized unmet medical need. Consequently, the search for new analgesic agents is being intensively studied by the pharmaceutical industry. The TRPV1 receptor is an ion channel that has been implicated in mediation of many types of pain and therefore studied most extensively. The first competitive antagonist, capsazepine, was first described in 1990, since then development of novel TRPV1 antagonists has come a long way. This effort has led to the identification of several TRPV1 antagonists that have entered clinical trials as analgesic agents. Should these new chemical entities relieve symptoms of chronic pain then this class of compounds may offer one of the first novel mechanisms for the treatment of pain, in many years.
