The naturally occurring alkaloid, conessine (6), was discovered to bind to histamine H3 receptors in a radioligand-based high-throughput screen. Conessine displayed high affinity at both rat and human H3 receptors (pKi = 7.61 and 8.27) and generally high selectivity against other sites, including histamine receptors H1, H2, and H4. Conessine was found to efficiently penetrate the CNS and reach very
