Inotodiol activates p53 signaling pathway, inhibits MMP-2/9, and exhibits antitumor activity in cancer cell HeLa. Inotodiol inhibits the generation of ROS and exhibits antioxidant and neuroprotective effects. Inotodiol inhibits the activation of MAPK and NF-kappaB signaling pathway, and exhibits anti-inflammatory activity. Inotodiol inhibits TLR-4 mediated TNF-alpha production (IC50s in BMMC and BMDM is 0.7 µM and 3.0 µM), inhibits the degranulation in mast cell, exhibits anti-allergic activity. Inotodiol is orally active[1][2][3][4][5].
