Isostearic acid (Isooctadecanoic acid) is an active ingredient in imiquimod formulations that promotes the entry of imiquimod or peripherally secreted cytokines into the brain, and can be used to induce psoriasis-like disease models.

Linolelaidic acid ((9E,12E)-octadeca-9,12-dienoic acid) is a major positive regulator of CTL activity, an essential nutrient for humans, with anti-inflammatory and anti-parasitic properties. It improves metabolic adaptability, prevents fatigue, and stimulates memory-like phenotypes with exceptional effects. It induces apoptosis and can be used in infection studies.

(Rac)-Idroxioleic acid (2-Hydroxyoleic acid) is a fatty acid amide hydrolase inhibitor with anti-tumor properties that binds to the plasma membrane, altering lipid organization.

4-Oxododecanedioic acid is an organic acid containing a ketone group that can be used in studies related to organic synthesis and fatty acid metabolism. Studies related to its structural analog dodecanedioic acid have found that intake of long-chain dicarboxylic acid increases beta-oxidation of fatty acids, decreases body fat accumulation, and improves glucose tolerance.

alpha-Eleostearic acid (cis-eleostearic acid) is a conjugated fatty acid present in Anemone seeds and can be used as a chemical taxonomic marker for Anemone.

Stearidonic Acid (6Z,9Z,12Z,15Z-Octadecatetraenoic acid) is a plant-based omega-3 fatty acid extracted from brown algae, a precursor in the biosynthetic pathway, used for Alzheimer's disease research.

13(S)-HpODE, a metabolite present in potato and Homo sapiens, is the (S)-enantiomer of 13-HpODE, a fatty acid containing a peroxy group, IL-13 13(S)HpODE stimulates MAO-A-mediated intracellular ROS generation and induction of p53 as well as p21 during apoptosis of A549 cancer cells and promotes apoptosis of HCT116 and CCF52 cells by upregulating p53 and p21 expression promoted apoptosis in HCT116 and CCF52 cells, constituting the IL-13 > 15-LO > 13(S)HpODE > PPARγ > MAO-A > ROS > p53 > p21 axis.

Paullinic acid (cis-13-eicosenoic acid) is a long-chain fatty acid extracted from Tinospora crispa.

Pinolenic Acid (PNLA) is an omega-6 polyunsaturated fatty acid extracted from pine nuts, with anti-inflammatory, anticancer, and lipid-lowering activities, improving oleic acid-induced lipogenesis and oxidative stress in HepG2 cells, useful in breast cancer research.

Punicic acid (Trichosanic acid) is a naturally occurring conjugated linolenic acid and polyunsaturated fatty acid that is anti-obesity and anti-diabetic through activation of PPARα, PPARβ, PPARγ, and inhibition of NF-κB; anti-inflammatory through inhibition of cyclooxygenase (COX) and lipoxygenase (LOX); improves neuroinflammation; and prevention of osteoporosis.

12(S)-HHT (12(S)-HHTrE), a fatty acid produced via the arachidonic acid metabolic pathway of cyclooxygenase (COX), is an endogenous ligand and agonist of BLT2, and the 12(S)-HHT BLT2 axis plays a role in the maintenance of homeostatic aspects of epithelial tissues and in inflammatory responses. 12(S)-HHT inhibits the p38 MAPK NF-κB pathway through upregulation of MKP-1, leading to reduced IL-6 synthesis in UVB-irradiated HaCaT cells.
