Administration of piperine appears to reverse preexisting high-fat diet (HFD)-induced hepatic steatosis and insulin resistance, probably by activation of adiponectin-AMPK signalling.

Lutein and lycopene has chemopreventive activity, the possible mechanism is their antioxidant effects.

Hydrastine is a natural product found in Hydrastis canadensis. It has a role as a metabolite.

Dehydrocorydalin has anti-inflammatory,antinociceptive,antiplatelet,and anti-tumor effects and can protect the cardiovascular system. Dehydrocorydaline stimulates p38 MAPK activation, which can enhance heterodimerization of MyoD and E proteins, thus resulting in MyoD activation and myoblast differentiation. Dehydrocorydaline inhibits MCF-7 cell proliferation by inducing apoptosis mediated by regulating Bax/Bcl-2, activating caspases as well as cleaving PARP.

4-Hydroxyisoleucine is an isoleucine derivative. 4-Hydroxyisoleucine has antidepressant-like, antidyslipidemic, and antihyperglycemic effects. It acts to improve insulin resistance by promoting mitochondrial biogenesis in high fructose diet fed STZ induced diabetic rats, it also has beneficial effects on low-grade inflammation. 4-Hydroxyisoleucineis an orally active amino acid that can be isolated from fenugreek seeds. 4-Hydroxyisoleucine has insulin promoting and anti diabetes properties.

Picrocrocin is a beta-D-glucoside of beta-cyclocitral; the precursor of safranal. It is the compound most responsible for the bitter taste of saffron. It is functionally related to a beta-cyclocitral.

Harmine hydrochloride has potent anti-cancer effects in glioblastoma cells, which is at least partially via inhibition of Akt phosphorylation.

Syringin is a monosaccharide derivative that is trans-sinapyl alcohol attached to a beta-D-glucopyranosyl residue at position 1 via a glycosidic linkage. It has a role as an autophagy inducer, an antidepressant, a hepatoprotective agent, a neuroprotective agent, an anti-inflammatory agent, an apoptosis inducer and a plant metabolite. It is a primary alcohol, a beta-D-glucoside, a dimethoxybenzene and a monosaccharide derivative. It is functionally related to a trans-sinapyl alcohol.

Cytisine is an organic heterotricyclic compound that is the toxic principle in Laburnum seeds and is found in many members of the Fabaceae (legume, pea or bean) family. An acetylcholine agonist, it is widely used throughout Eastern Europe as an aid to giving up smoking. It has a role as a phytotoxin, a nicotinic acetylcholine receptor agonist and a plant metabolite. It is an alkaloid, a lactam, an organic heterotricyclic compound, a bridged compound and a secondary amino compound. Cytisine is a nicotinic acetylcholine receptor agonist, has been widely used for central nervous system (CNS) diseases treatment. It is a partial agonist at alpha4/beta2 nAChRs, and a full agonist at alpha3/beta4 and alpha7 nAChRs, has antidepressant-like properties in several rodent models of antidepressant efficacy.

Crocin is a water-soluble carotenoid pigment of saffron (Crocus sativus L.), it has been used as a spice for flavoring and coloring food preparations. Crocin has anti-inflammatory, anti-oxidative, anti-apoptotic, anti-asthma, anti-cancer, and hypolipidemic effects. Crocin improves toxic effects of diazinon via reducing lipid peroxidation and restoring altered contractile and relaxant responses in rat aorta; it also protects retinal photoreceptors against light-induced cell death. Crocin can also promote ovarian cancer HO-8910 cell apoptosis, most likely by increasing p53 and Fas/APO-1 expression, and then activating the apoptotic pathway regulated by Caspase-3. Bis(beta-D-glucosyl) crocetin is a diester resulting from the formal condensation of each of the carboxylic acid groups of crocetin with an anomeric hydroxy group of beta-D-glucopyranose. It is a beta-D-glucoside and a diester. It is functionally related to a beta-D-glucose and a crocetin.

Beta-D-gentiobiosyl beta-D-glucosyl crocetin is a diester resulting from the formal condensation of the carboxylic acid group of beta-D-gentiobiosyl crocetin with the anomeric hydroxy group of beta-D-glucopyranose. It is a beta-D-glucoside and a diester.

Epimedin C is a glycoside and a member of flavonoids.

Dehydroevodiamine has anticholinesterase activity and an anti-amnesic effect, it also may be a novel and effective ligand for improvement of beta-amyloid type amnesia. Dehydroevodiamine has antiarrhythmic, and anti-inflammatory properties, the effect of dehydroevodiamine-mediated inhibition of the expression LPS-induced iNOS and COX-2 genes is due to under the suppression of NF-kappaB activation in the transcriptional level.

Gelsemine is a highly toxic compound and may be a glycine receptor agonist. Gelsemine has antitumor, anti-hyperlipidemic,anti-oxidative activities,it also has marked antinociception in inflammatory, neuropathic and bone cancer pains without inducing antinociceptive tolerance.

Homovanillic acid is a monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite. It has a role as a mouse metabolite and a human metabolite. It is a member of guaiacols and a monocarboxylic acid. It is functionally related to a (3,4-dihydroxyphenyl)acetic acid. It is a conjugate acid of a homovanillate. Homovanillic acid is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain. Abnormalities in white matter were associated with low CSF Homovanillic acid.
