Coronaridine, also known as 18-carbomethoxyibogamine, is an alkaloid found in Tabernanthe iboga and related species, including Tabernaemontana divaricata for which (under the now obsolete synonym Ervatamia coronaria) it was named.[1]
Like ibogaine, (R)-coronaridine and (S)-coronaridine can decrease intake of cocaine and morphine in animals[2] and it may have muscle relaxant and hypotensive activity.[3]
Chemistry
Congeners
Coronaridine congers are important in drug discovery and development due to multiple actions on different targets. They have ability to inhibit Cav2.2 channel,[4] modulate and inhibit subunits of nAChr selectively such as α9α10,[4] α3β4[5][6] and potentiate GABAA activity.[7]
Pharmacology
Coronaridine has been reported to bind to an assortment of molecular sites, including: μ-opioid (Ki = 2.0 μM), δ-opioid (Ki = 8.1 μM), and κ-opioid receptors (Ki = 4.3 μM), NMDA receptor (Ki = 6.24 μM) (as an antagonist),[8] and nAChRs (as an antagonist).[9] It has also been found to inhibit the enzyme acetylcholinesterase, act as a voltage-gated sodium channel blocker,[10] and displays estrogenic activity in rodents.[8][9] In contrast to ibogaine and other iboga alkaloids, coronaridine does not bind to either the σ1 or σ2 receptor.[10]
