Argopsin, also known as 1-chloropannarin, is a secondary metabolite produced by many lichen species, such as Biatora cuprea[1] and Micarea lignaria.[2] Argopsin was first isolated from the lichen Argopsis friesiana.[3] The chemical name of argopsin is 2,7-dichloro-3-hydroxy-8-methoxy-1,6,9-trimethyl-11-oxo-11H-dibenzo[b,e][1,4]dioxepin-4-carbaldehyde.

Uses

edit

Argopsin can have photohemolytic effect when activated under ultraviolet light with a wavelength of 366 nm.[4]

Argopsin has been shown to have an in vitro effect on Leishmania at a concentration of 50 μg/ml.[5]
