A cyclic oligosaccharide containing seven D-(+)-glucopyranose units that is widely used to improve the aqueous solubility of various compounds, especially those containing a phenyl group.

Oleic acid is a monounsaturated fatty acid and is one of the major components of membrane phospholipids. Oleic acid contributes about 17% of the total fatty acids esterified to phosphatidylcholine, the major phospholipid class in porcine platelets. Oleic acid inhibits collagen-stimulated platelet…

A potent antioxidant that inhibits the oxidation of cholesterol in LDL and HDL by impairing the translocation of ABCA1 from intracellular compartments to the plasma membrane.

A deoxyhexose monosaccharide found on N- and O-linked glycans and glycolipids that exists either as a terminal modification of glycan structures or serves as a point of attachment for adding other sugars; plays a role in A and B blood group antigen substructure determination, selectin-mediated…

Ciclopirox is a hydroxypyridone compound that exhibits antifungal, anti-inflammatory, anti-angiogenic, and anticancer chemotherapeutic activities. This compound acts as a metal ion chelator, preventing peroxide degradation. Ciclopirox modulates generation of ROS in a PKA/Ras1/Ras2-dependent manner,…

Catechin is a polyphenolic flavonoid which has been isolated from a variety of natural sources including tea leaves, grape seeds, and the wood and bark of trees such as acacia and mahogany. Catechin is a more potent antioxidant than ascorbate or α-tocopherol in certain in vitro lipid…

A class III antiarrhythmic agent; inhibits KCNH2 with an IC₅₀ value of 1 µM; also inhibits CYP2C8 and CYP3A4 in vitro at low micromolar concentrations.

A synthetic antibiotic that inhibits dihydrofolate reductase (DHFR), with prominent selectivity for bacterial DHFR over mammalian DHFR (IC₅₀s = 5 and 30,000 nM, respectively); commonly used in combination with sulfamethoxazole to minimize acquired resistance.

An atypical, second generation antipsychotic compound that has effects at multiple receptors; antagonizes dopamine D1, D2, and D3 receptors, serotonin 5-HT1A, 5-HT2A, and 5-HT7 receptors, and α1A, α1B, and α2C adrenergic receptors.

A fluorogenic substrate of β-glucuronidase that upon cleavage yields a blue fluorescent end product that can be monitored by UV light; typically used in the GUS reporter system for fluorescent detection of β-glucuronidase gene expression in E. coli and transformed plants.

An orally active broad spectrum antifungal agent that blocks ergosterol biosynthesis by inhibiting the fungal CYP isoform CYP51; potently inhibits the mammalian analog CYP51A1 (IC₅₀ = 63.5 nM), as well as a variety of other CYP isoforms.

A yellow breakdown product of heme catabolism, formed when heme is cleaved by heme oxygenase; has key roles as a free radical scavenger with antioxidant and anti-inflammatory actions.

A citrus-derived flavonoid that inhibits CYP3A4 activity in human liver microsomes (IC₅₀s = 139-188 μM); demonstrates antifibrotic, lipid lowering, and insulin-like properties.

A red/orange-colored fat-soluble terpenoid with antioxidant properties; can be cleaved to produce vitamin A and retinoic acid.

A natural form of vitamin A that is thermally more stable than retinol; can reduce cell proliferation and promote differentiation.

A broad-spectrum benzimidazole anthelmintic that is active against gastrointestinal parasites (IC₅₀ = 0.30 µM against Giardia in vitro) by targeting tubulin; activates HIF-1α, abrogating oxidative stress-induced death in primary neurons in vitro.

A non-ionic detergent commonly used to solubilize membrane-associated proteins; helps retain the native conformation and activity of membrane-associated proteins, and facilitates the reforming of these proteins after denaturation.

An N-acetylglucosamine derivative that has been shown to promote hyaluronic acid production.

An an antimicrobial agent that is often used in antiseptics and dental products such as toothpaste and mouthwash; inhibits MMP-2, -8, and -9.
