α,β-unsaturated

(Z)-2-decenoic acid (cis-dec-2-enoic acid) is an unsaturated short-chain fatty acid secreted by Pseudomonas aeruginosa. It can induce a dispersion response in biofilms formed by gram-negative and gram-positive bacteria and can also inhibit biofilm development.

trans-2-Undecenoic acid ((E)-Undec-2-enoic acid) ((E)-2-Undecenoic acid) is an α,β-unsaturated carboxylic acid characterized by acid dimers.

Isophorone is a clear liquid that smells like peppermint. It can be dissolved in water and evaporates somewhat faster than water.

Levomenol ((-)-α-BISABOLOL) is a sesquiterpene alcohol that has been found in the essential oils of several aromatic plants, with exerts antioxidant, anti-inflammatory, and anti-apoptotic activities.

Sesamin is a selective delta 5 desaturase inhibitor in the biosynthesis of polyunsaturated fatty acids and is a lignan abundantly present in sesame oil. It has potent neuroprotective effects against cerebral ischemia.

Linoleic acid (9,12-octadecadienoic acid) is a naturally occurring polyunsaturated fatty acid found in animal and vegetable oils. Linoleic acid is an essential fatty acid that is part of membrane phospholipids.

Eicosapentaenoic Acid is an ω-3 fatty acid and an inhibitor of fatty acid synthase (FASN). Eicosapentaenoic Acid promotes DNA demethylation in the reexpression of the tumor suppressor gene CCAAT/ enhancer-binding protein δ (C/EBPδ). Eicosapentaenoic Acid activates the RAS/ERK/C/EBPβ pathway in U937 leukemia cells through demethylation of the CpG island of H-RAS intron 1. Eicosapentaenoic Acid promotes the relaxation of vascular smooth muscle cells and vasodilation.

Adrenic Acid (cis-7,10,13,16-Docosatetraenoic acid) is a very-long-chain fatty acid present in blood and human myelin tissue.

Eicosadienoic acid is a rare, natural n-6 polyunsaturated fatty acid found mainly in animal tissues.

(-)-Cleistenolide, an α,β-unsaturated δ-lactone derived from Cleistochlamys kirkii Oliver, exhibits antibacterial and antitumor activity [1].

Trans-2-Hexenal (trans-2-Hexenal) is an α,β-unsaturated carbonyl compound protecting plants against harmful substances.

Cyclocurcumin is a minor curcuminoid derived from the rhizome of Curcuma longa that differs structurally from curcumin despite sharing the same molecular formula (C21H20O6), Cyclocurcumin features an α,β-unsaturated dihydropyranone moiety that drives trans–cis photoisomerization instead of the diketone/keto–enol tautomerism characteristic of curcumin. Cyclocurcumin demonstrates potent biochemical activities, including selective inhibition of human aromatase (CYP19A1) with an IC50 of 4.43 μM—approximately fivefold stronger than curcumin—making it valuable for studying estrogen-related pathways, and uniquely stimulates melanogenesis and melanin export in both melanocyte and melanoma models, positioning it as a promising research tool for investigating hypopigmentary skin disorders.
