Conessine is a steroid alkaloid found in a number of plant species from the Apocynaceae family, including Holarrhena floribunda,[1] Holarrhena antidysenterica[2] and Funtumia elastica.[3] It acts as a histamine antagonist, selective for the H3 subtype (with an affinity of pKi = 8.27; Ki = ~5 nM).[4] It was also found to have long CNS clearance times, high blood-brain barrier penetration and high affinity for the adrenergic receptors.[5]
