bone erosion

Eleutheroside E has anti-inflammatory effects by inhibiting NF-κB activities. Eleutheroside E significantly decreases the inflammatory cell infiltration, pannus formation, cartilage damage, bone erosion of CIA mice, the generation of TNF-α and IL-6, the m

1. (±)-Praeruptorin A could exhibit its anti-osteoclastogenic activity by inhibiting p38 Akt-c-Fos-NFATc1 signaling and PLCγ-independent Ca(2+) oscillation 2. Praeruptorin A has the potential to inhibit migration fusion of preosteoclasts in vitro and bone erosion in vivo by targeting calmodulin and inhibiting the Ca(2+) calmodulin-CaMKIV-CREB-NFATc1 and or Ca(2+) calmodulin-calcineurin-NFATc1 signaling axis. 3. Praeruptorin A and praeruptorin C can significantly upregulate multidrug resistance-associated protein 2 expression via the constitutive androstane receptor-mediated pathway in vitro, and this should be taken as an herb-drug interaction.

Praeruptorin A ((+)-Praeruptorin A) has the potential to inhibit migration fusion of preosteoclasts in vitro and bone erosion in vivo by targeting calmodulin and inhibiting the Ca(2+) calmodulin-CaMKIV-CREB-NFATc1 and or Ca(2+) calmodulin-calcineurin-NFATc1 signaling axis.
