Atranorin shows significant antinociceptive and antiinflammatory activities, it has a relevant redox-active action, acting as a pro-oxidant or antioxidant agent depending on the radical, also, it will exert cytoprotective effects on cells under oxidative stress induced by H(2)O(2).

三种地衣次生代谢产物Atranorin (1)、evernic acid (2)和usnic acid (3)，采用细胞膜双分裂阻断微核试验（CBMN）在最终培养溶液中2μg/ml、4μg/ml和6μg/ml的浓度下，对其体外对人类淋巴细胞的细胞遗传毒性和抗增殖效应进行了评估。在2μg/ml和4μg/ml的浓度下，Atranorin 仅将MN频率降低了11.1%和1.8%，而在6μg/ml的浓度下，MN频率增加了9.6%。
