Compounds that inhibit receptors by preventing the natural messenger from binding are known as antagonist.
Antagonists are molecules that will block the binding of the natural messenger at a receptor molecule. As a result, the signal which is usually produced by a receptor-messenger coupling will be inhibited. <span>An antagonist can be a drug that blocks a biological response by binding to and blocking a receptor.</span>
