Protopine acts as a potent inhibitor of thromboxane synthesis and PAF with hepatoprotective, antidepressant, antioxidant, antispasmodic and relaxant properties. Protopine is also a novel microtubule-stabilizing agent, causes mitotic arrest and apoptotic cell death in human hormone-refractory prostate cancer cell lines. Protopine blocks phosphorylation of mitogen-activated protein kinases (MAP kinases) and also blocks activation of a nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB). Protopine is a dibenzazecine alkaloid isolated from Fumaria vaillantii. It has a role as a plant metabolite.

Isopteropodine has antimicrobial activity, it shows strong apoptotic effects on acute leukaemic lymphoblasts, it also shows an ability to stimulate the immune system.

Isovalerylshikonin, a new resistance-modifying agent from Arnebia euchroma, supresses antimicrobial resistance of drug-resistant Staphylococcus aureus; it also has anti-mite activity. Isovalerylshikonin as a candidate of AChE inhibitor, it may prevent apoptotic cell death induced by hydrogen peroxide in human and rat neuronal SH-SY5Y and PC12 cells.

Isobavachromene is an inhibitor of NADH-Ubiquinone oxidoreductase and ornithine decarboxylase. Isobavachromene has antifungal activity.

3,4'-dimethylkaempferol is a dimethoxyflavone that is kaempferol in which the hydroxy groups at position 3 and 4' have been replaced by methoxy groups. It is a component of bee glue and isolated from several plant species including Tanacetum microphyllum. It has a role as an antineoplastic agent, an antimycobacterial drug, an anti-inflammatory agent, an apoptosis inducer and a plant metabolite. It is a dimethoxyflavone and a dihydroxyflavone. It is functionally related to a kaempferol. Ermanin shows anti-inflammatory activity by suppressing the iNOS and COX-2 expression. Ermanin may have anti-HIV-1activity. Ermanin also has a high deterrent activity at 40 ppm against Dione juno larvae.

Menthone has anti-inflammary activity, it can suppress the lipopolysaccharide (LPS)-induced proinflammatory cytokines, interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha), as well as nuclear factor kappaB (NF-kappaB) activity induced by LPS and other inflammatory agents. Menthone and menthol enhances the skin permeability by disordering the ordered organization of SC lipids and extracts part of SC lipids. P-menthan-3-one is a p-menthane monoterpenoid that is p-menthane substituted by an oxo group at position 3. It has a role as a volatile oil component and a plant metabolite.

Picfeltarraenin IV is a natural product from Picria felterrae Lour.

Berberine has neuroprotective, antidepressant, antineoplastic, and anti- fibrosis activities; it is a potent oral hypoglycemic agent with beneficial effects on lipid metabolism, it may as a broad-spectrum anti-microbial medicine, a complementary therapeutic agent for HIV/AIDS; it also may be one of the targeted therapeutic agents that can restore barrier function in intestinal disease states.Berberine is used in histology for staining heparin in mast cells. As a natural dye, berberine has a colour index of 75160. Berberine is a berberine alkaloid, an organic heteropentacyclic compound, an alkaloid antibiotic and a botanical anti-fungal agent. It has a role as a geroprotector, an antioxidant, a metabolite, a hypoglycemic agent, an EC 3.1.3.48 (protein-tyrosine-phosphatase) inhibitor, an antineoplastic agent, an antilipemic drug, an EC 3.1.1.8 (cholinesterase) inhibitor, an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an EC 1.1.1.21 (aldehyde reductase) inhibitor, an EC 3.1.1.
