2',3'-cGAMP sodium (2'-3'-cyclic GMP-AMP sodium) is a second messenger in cellular innate immunity, catalyzed by cGAMP synthase (cGAS) under DNA binding conditions. It binds to STING to form a dimer, inducing the production and expression of interferon-β and other cytokines.

Capsaicin ((E)-Capsaicin) is a natural product extracted from Capsicum annuum, and is a TRPV1 agonist (EC50=0.29 μM). Capsaicin has antitumor, anti-inflammatory, antioxidant and neuroprotective activities.

Lipopolysaccharides (LPS) derived from Escherichia coli 055:B5, are a unique component of the cell wall of Gram-negative bacteria. They are composed of three regions: lipid A, oligosaccharide core, and O-specific polysaccharide (O-antigen). Lipopolysaccharides help maintain the integrity of the cell outer membrane and protect bacteria from damage by bile salts and lipid antibiotics. Lipopolysaccharides are highly immunogenic antigens that can enhance immune responses and can be used to construct inflammatory models.

Deoxynivalenol (Vomitoxin) is a mycotoxin produced by Fusarium spp. of the single trichothecene family and is commonly found in contaminated food and feed.Deoxynivalenol crosses the intestinal mucosa via a cellular bypass at the tight junctions.Deoxynivalenol transporters are unaffected by inhibitors of P-glycoprotein (PgP) or multidrug resistance-associated protein (MRP). Deoxynivalenol commonly causes diarrhea, vomiting, and gastrointestinal inflammation in humans and animals.

Resveratrol (SRT 501) is a polyphenolic natural product, a plant antitoxin with antioxidant and chemopreventive activities. Resveratrol has a wide range of targets including COX, SIRT, LOC, etc. Resveratrol induces autophagy and apoptosis.

3-Methyladenine (3-MA) is a PI3K inhibitor that selectively inhibits class IB PI3Kγ (IC50 = 60 μM) and class III VPS34 (IC50 = 25 μM). 3-Methyladenine inhibits autophagy.

Puromycin dihydrochloride (CL13900 dihydrochloride) is a cinnamamide adenosine antibiotic and an inhibitor of protein synthesis. Puromycin dihydrochloride inhibits protein synthesis by binding to RNA and has antitumor and antitrypanosomal activity.

Tauroursodeoxycholate (UR 906), also known as ursodoxicoltaurine, is a highly hydrophilic tertiary bile acid that is produced in humans at a low concentration. Tauroursodeoxycholate is the more hydrophilic form of ursodeoxycholic acid, which is the more abundant naturally produced bile acid in humans.Tauroursodeoxycholate is being investigated for use in several conditions such as Primary Biliary Cirrhosis (PBC), insulin resistance, amyloidosis, Cystic Fibrosis, Cholestasis, and Amyotrophic Lateral Sclerosis.

Palmatine chloride an isoquinoline alkaloid, is an important medicinal herbal extract with diverse pharmacological and biological properties.

Scutellarin (Scutellarein-7-glucuronide), an active flavone isolated from Scutellaria baicalensis, can inhibit RANKL-mediated MAPK and NF-κB signaling pathway in osteoclasts, and down-regulate the STAT3 Girdin Akt signaling in HCC cells.

Astragaloside IV (AS-IV), an active component isolated from Astragalus membranaceus, suppresses the activation of ERK1 2 and JNK, and downregulates matrix metalloproteases (MMP)-2, (MMP)-9 in MDA-MB-231 breast cancer cells. Astragaloside IV is a bioactive saponin first isolated from the dried plant roots of the genus Astragalus, which is used in traditional Chinese medicine.1 It dose-dependently inhibits human adenovirus type 3 (HAdV-3) in A549 cells (IC50 = 23 μM; LC50 = 865 μM).It inhibits replication of HAdV-3 and decreases HAdV-3-induced apoptosis. It has diverse protective effects for the cardiovascular, immune, digestive, and nervous systems. In particular, it reduces myocardial infarct size in dogs when administered prior to coronary ligation and reduces reperfusion arrhythmias in isolated rat hearts.

Citronellol ((±)-β-Citronellol) is used in insect repellents and perfumes and as a mite attractant.

Polyphyllin D induces apoptosis via the mitochondrial apoptotic pathway as evidenced by decreased Bcl-2 expression levels, disruption of MMP and increased Bax, cytochrome C, and cleaved-caspase-3 levels. Polyphyllin D has an anti-angiogenic effect. Polyphyllin D has toxicity in human RBCs as well as its underlying mechanism for the hemolysis and eryptosis erythroptosis. Polyphyllin D has strong anticancer activity, can overcome drug resistance in R-HepG2 cells and elicit programmed cell death via mitochondrial dysfunction.

Trimethylamine N-oxide (TMAO) is a colorless amine oxide produced from choline, betaine, and carnitine via intestinal microbial metabolism that accumulates in tissues of marine animals and prevents the protein-damaging effects of urea.Trimethylamine N-oxide induces inflammation through activation of ROS NLRP3 inflammasomes, which can induce fibroblast differentiation and cardiac fibrosis.
