Arnicolide D is a sesquiterpene lactone. Arnicolide D isolates from Centipeda minima. Arnicolide D modulates the cell cycle, activates the caspase signaling pathway and inhibits the PI3K AKT mTOR and STAT3 signaling pathways.

(2S,3R,4S)-4-Hydroxyisoleucine (Hydroxyisoleucine) from fenugreek (Trigonella foenum-graecum) seeds is a potential insulinotropic (anti-diabetic) and anti-obesity amino acid that stimulates glucose-dependent insulin secretion from pancreatic cells, activates insulin receptor substrate-associated phosphoinositide 3 (PI3) kinase activity, and reduces plasma levels of triglycerides, free fatty acids, and cholesterol.

1-Deoxynojirimycin (Moranoline) is a potent α-glucosidase inhibitor, suppressing postprandial blood glucose, thereby possibly preventing diabetes mellitus.

Increased levels of erucic acid (22:1n9) have been found in the red blood cell membranes of autistic subjects with developmental regression (PMID: 16581239 ). Erucic acid (13(Z)-Docosenoic Acid) is broken down long-chain acyl-coenzyme A (CoA) dehydrogenase, which is produced in the liver. This enzyme breaks this long chain fatty acid into shorter-chain fatty acids. human infants have relatively low amounts of this enzyme and because of this, babies should not be given foods high in erucic acid. Erucic acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism.

Musk ketone can induce the growth repression and the apoptosis of cancer cells. Musk ketone increases activity of glutathione S-transferase and thus may prove to be useful cancer chemoprotectant.

Quercetin Dihydrate (Sophoretin) is a polyphenolic flavonoid that was found in a wide variety of plant-based foods, such as apples, onions, berries, and red wine. It is used for their nervous system and anticancer effects.

Esculetin (Cichorigenin) is a coumarin derivative from various natural plant products with various biological and pharmaceutical properties including anti-edema, anti-inflammatory and anti-tumour effects. It inhibits lipoxygenases (LOs).

Solenopsin HCl is an alkaloid extracted from fire ants, inhibiting phosphoinositide 3-kinase signaling and angiogenesis in a dose-dependent manner, affecting cardiovascular function, and used in cardiovascular disease research.

Isorhamnetin (3-methylquercetin) is the methylated metabolite of quercetin. Quercetin is an important dietary flavonoid with in vitro antioxidant activity. Isorhamnetin prevents endothelial cell injuries from oxidized LDL via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin. Isorhamnetin prevents endothelial dysfunction, superoxide production, and overexpression of p47phox induced by angiotensin II. Isorhamnetin appears to be a potent drug against esophageal cancer due to it's in vitro potential to not only inhibit proliferation but also induce apoptosis of Eca-109 cells.

Polygalasaponin F has anti-neuroinflammatory activity, can inhibit the release of inflammatory cytokines TNF-α and NO induced by lipopolysaccharides (LPS) and reduce the expression of inducible nitric oxide synthases. Polygalasaponin F can significantly i

Oroxin B has antioxidant activity.

1. Glaucocalyxin A (Leukamenin F)-SBE-β-CD could be useful with a better solubility and sustained function in drug delivery. 2. Glaucocalyxin A activates caspase-3, decreases BAD phosphorylation, and reduces the expression of X-linked inhibitor of apoptosis protein. 3. Glaucocalyxin A inhibits Akt phosphorylation, suppresses proliferation, and promotes apoptosis in a dose-dependent manner, but not in normal glial cells. 4. Glaucocalyxin A inhibits collagen-stimulated tyrosine phosphorylation of Syk, LAT, and phospholipase Cγ2, the signaling events in collagen receptor GPⅥ pathway. 5. Glaucocalyxin A could potentially be developed as an antiplatelet and antithrombotic agent, can inhibit platelet p-selectin secretion and integrin activation by convulxin, is a GPVI selective ligand.

(+)-Nortrachelogenin is a lignan isolated from Wikstroemia indica C.A. Meyer (Thymelaeaceae). (+)-Nortrachelogenin possesses antileukemic activity.

Brevianamide F (Cyclo(L-Pro-L-Trp)), also known as cyclo-(L-Trp-L-Pro), is a naturally occurring 2,5-diketopiperazine with notable breast cancer resistance protein inhibitory activity.

Ginsenoside Rk1 is a component created by processing the ginseng plant at high temperatures. Ginsenoside Rk1 has an anti-inflammatory effect, suppresses the activation of Jak2 Stat3 signaling pathway and NF-κB. It also has an anti-tumor effect.

Phosphatidylinositol 4,5-bisphosphate (L-alpha-Phosphatidylinositol-4,5-bisphosphate), a critical phospholipid in cell membranes, serves as a substrate for both phospholipase C (PLC) and phosphoinositide 3-kinase (PI3K) and acts as a primary messenger [1] [2] [3].

1,3-Dicaffeoylquinic acid (CYNARIN) is a natural product. It shows antioxidant and choleretic properties and is a potential immunosuppressive agent.

Heterophyllin B effectively suppresses the adhesion and invasion of the human esophageal carcinoma cells by mediating the PI3K AKT β-catenin pathways and regulating the expression levels of adhesion- and invasion-associated genes.

Hederacolchiside A1 (Raddeanoside R13) shows anti-leishmanial activity, it exhibits a strong antiproliferative activity on all stages of development of the parasite by altering membrane integrity and potential.
