Tovophyllin A
Tovophyllin A is an orally active xanthonoid compound. Tovophyllin A exerts neuroprotective effects against Parkinson's disease by activating the Akt/GSK3β signaling pathway. Tovophyllin A protects mouse models of liver injury by activating Nrf2. Tovophyllin A exhibits protective anti-inflammatory activity in mouse models of acute lung injury. Tovophyllin A inhibits the activation of NF-κB and subsequent release of pro-inflammatory cytokines. Tovophyllin A reduces apoptotic cell death (Apoptosis). Tovophyllin A has antiplasmodial activity. Tovophyllin A shows cytotoxic activity against lung epithelial cancer cells and breast cancer cells. Tovophyllin A can be used in research related to Parkinson's disease, liver injury, acute lung injury, lung epithelial cancer, and breast cancer.

Tovophyllin A (0.01-20 μM; 24 h) protects primary cortical neurons against MPP+- and paraquat (PQ)-induced neurotoxicity. After 24 h of co-treatment, it significantly increases cell viability in the MPP+ model at concentrations ≥0.1 μM and in the PQ model at concentrations ≥1 μM[1].
Tovophyllin A (serial twofold dilutions starting at 200 μM; 48 h) inhibits the proliferation of A549 human lung adenocarcinoma cells and MCF7 breast cancer cells, with IC50 values of 2.2 μM and 6.1 μM, respectively[3].

Tovophyllin A (50-100 mg/kg; p.o.; once daily; 5 days) dose-dependently protects male BALB/c mice against Acetaminophen (HY-66005)-induced acute liver injury. At the dose of 100 mg/kg, it almost completely reverses hepatic necrosis, oxidative stress and the elevation of inflammatory mediators, and potently activates the Nrf2 cytoprotective pathway[2].
Tovophyllin A (50-100 mg/kg; p.o.; daily; 5 days prior to LPS challenge) improves LPS (HY-D1056)-induced acute lung injury in male BALB/c mice in a dose-dependent manner[3].
