Moronic acid (3-oxoolean-18-en-28-oic acid) is a natural triterpene.[1][2]
Moronic acid can be extracted from Rhus
javanica, a sumac plant traditionally believed to hold medicinal
applications.[2]
The molecule has also been extracted from Mistletoe (Phoradendron
reichenbachianum).[3]
Bevirimat, a
derivative of the related triterpenoid betulinic
acid, is under development as an anti-HIV drug; however,
moronic acid has shown better antiviral profiles in vitro
than bevirimat.[4]
A particular moronic acid derivative showed potent anti-HIV activity with EC50 values
of 0.0085 μM against NL4-3, 0.021 μM against PI-R (a multiple protease
inhibitor resistant strain), and 0.13 μM against FHR-2 (an HIV strain resistant
to (bevirimat). This derivative has become a new lead for clinical trials and
is also active against herpes simplex virus 1.[4]
