Background

Atranorin is a depside lichen metabolite that has been found in S. alpinum and has diverse biological activities.^1,2,3,4 It is active against the bacteria B. cereus, B. subtilis, S. aureus, S. faecalis, P. vulgaris, L. monocytogenes, and A. hydrophila (MICs = 1.67, 0.38, 26.7, 13.4, 3.34, 9.83, and 1.67 mM, respectively), the fungi C. albicans and C. glabrata (MIC = 26.7 mM for both), as well as the mycobacterium M. aurum (MIC = 250 µg/ml).^1,2 Atranorin 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).³ It inhibits acetic acid-induced writhing in mice when administered orally at doses of 200 and 400 mg/kg.⁴ Atranorin (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.
