Conessine is a by itself occurring steroid alkaloid begin in a amount of bulb breed from the Apocynaceae family, including Holarrhena floribunda, Holarrhena antidysenterica and Funtumia elastica, several of which are acclimated in acceptable herbal anesthetic as a analysis for amoebic dysentery. which accept been acclimated in acceptable herbal anesthetic as a analysis for amoebic dysentery.
In a radioligand-based high-throughput screen, conessine approved top affection for both rat and animal histamine H3 receptors (Kis = 5.2 and 24.5 nM, respectively) and top selectivity adjoin histamine receptors H1, H2, and H4. Though conessine potently blocks H3 agonist-stimulated GTPγS bounden in cell- and tissue-based anatomic assays and calmly crosses the blood-brain barrier, it has a poor amount of CNS clearance.
