Background:
Atranorin is a depside lichen metabolite that has been found inS. alpinumand has diverse biological activities.1,2,3,4It is active against the bacteriaB. cereus,B. subtilis,S. aureus,S. faecalis,P. vulgaris,L. monocytogenes, andA. hydrophila(MICs = 1.67, 0.38, 26.7, 13.4, 3.34, 9.83, and 1.67 mM, respectively), the fungiC. albicansandC. glabrata(MIC = 26.7 mM for both), as well as the mycobacteriumM. aurum(MIC = 250 µg/ml).1,2Atranorin is cytotoxic to A270, HL-60, and Jurkat cancer cells (IC50s = 197.9, 93.5, and 181.6 µM, respectively) but not HeLa, MCF-7, SK-BR-3, or HT-29 cancer cells (IC50s = >200 µM).3It inhibits acetic acid-induced writhing in mice when administered orally at doses of 200 and 400 mg/kg.4Atranorin (200 and 400 mg/kg, p.o.) also reduces paw licking and biting in the second, but not first, phase of the formalin test when administered 30 minutes prior to formalin in mice.
