Oroxylin A is a flavonoid compound, one of the main components extracted from Scutellariae radix. It possess a broad spectrum of pharmacological effects, especially anti-cancer, anti-inflammatory and neuroprotective activity. Oroxylin A inactivated HIF1α and reprogrammed fatty acid metabolism of HCT116 cells, decreasing intracellular fatty acid level and enhancing fatty acid oxidation. Oroxylin A improves attention-deficit hyperactivity disorder-like behaviors in spontaneously hypertensive rats via enhancement of dopamine neurotransmission and not modulation of GABA pathway as previously reported. Importantly, the present study indicates the potential therapeutic value of oroxylin A in the treatment of attention-deficit hyperactivity disorder. Both in vitro and in vivo study showed that oroxylin A possesses low toxicity, but the field was just limited in cancer research.

Pheophorbide A is a product of chlorophyll breakdown in plants. It is an active component of the Chinese medicinal herb Scutellaria barbata. Others report on extraction of the drug from sources as varied as spinach leaves and silkworm excreta, and on its confounding appearance in the digestive tracts of animals fed chlorophyll-containing food. Pheophorbide A acts as a photosensitizer in photodynamic therapy. Photoactivated pheophorbide A induces lipid peroxidation, arrests cell growth by activating apoptosis and/or necrosis. In vitro and animal studies have suggested some efficacy for pheophorbide A-mediated photodynamic therapy of cancers.
