15-Methoxypinusolidic acid has anti-inflammatory effects, it inhibits LPS-induced iNOS expression and NO production, independent on MAPK and NF-kappaB. 15-Methoxypinusolidic acid suppresses adipocyte differentiation through the inhibition of PPARgamma-dependent adipogenic gene expression.15-Methoxypinusolidic acid attenuates glutamate-induced excitotoxicity via stabilization of [Ca2+]i homeostasis and suppression of oxidative stress possibly through the actions on the NMDA receptors.15-Methoxypinusolidic acid induced apoptosis in murine microglial cells, presumably via inhibition of the cell cycle progression.
