12-oxo Leukotriene B4 (12-Oxo-LTB4) is a potent pro-inflammatory lipid mediator classified as a dihydroxy fatty acid that is enzymatically derived from arachidonic acid metabolism via the 5-lipoxygenase (5-LO) pathway, and it promotes a diverse array of leukocyte functional responses including cellular aggregation, stimulation of transmembrane ion fluxes, enhancement of lysosomal enzyme release, superoxide anion generation, chemotaxis, and chemokinesis; 12-oxo Leukotriene B4 is an initial oxidative metabolite formed from Leukotriene B4 via the LTB4 12-hydroxydehydrogenase pathway, which undergoes rapid enzymatic conversion first to 10,11-dihydro-12-oxo-LTB4 followed by reduction of the 12-oxo group to yield 10,11-dihydro-LTB4, and this metabolite exhibits significantly reduced biological potency, being approximately 70-fold less potent than LTB4 in stimulating Ca2+ mobilization in human neutrophils (EC50 = 33 nM vs. 0.46 nM) and also markedly less effective at stimulating neutrophil migration (EC50 = 170 nM vs. 2.7 nM).

Stephacidin B is a fungal metabolite that has been found inA. ochraceus.1Dimeric stephacidin B is rapidly converted to a monomer, avrainvillamide ,in vitro.2Stephacidin B is cytotoxic to a variety of cancer cells, including testosterone-independent PC3 and -sensitive LNCaP prostate cancer cells (IC50s = 0.37 and 0.06 μM, respectively) and estradiol-independent SK-BR-3 and -sensitive MCF-7 breast cancer cells (IC50s = 0.32 and 0.27 μM, respectively).1It induces apoptosis in HepG2 and Huh7 hepatocellular carcinoma cells when used at a concentration of 4 μM.3 1.Qian-Cutrone, J., Huang, S., Shu, Y.-Z., et al.Stephacidin A and B: Two structurally novel, selective inhibitors of the testosterone-dependent prostate LNCaP cellsJ.

12-OxoETE is an endogenous metabolite formed during the metabolism of arachidonic acid and is present in human platelets and Aplysia nervous tissue .12-KETE induces transient changes and aggregation of intracytoplasmic free calcium ion concentration via leukotriene B4 (LTB4) receptor or coactivation sequences to achieve a rapid and dose-dependent increase.

Clinodiside A in rats with one compartment open model into the body, rapid distribution, elimination rate.

Scopolamine is a high-affinity (nanomolar level) muscarinic receptor antagonist that can reversibly inhibit 5-HT₃ receptor responses (IC₅₀ = 2.09 μM). It is commonly used to induce animal models of Alzheimer's disease or memory impairment.

4-Methylumbelliferyl-β-D-xylopyranoside (4-Methylumbelliferyl-β-D-xyloside) exhibits bursting steady-state kinetics in biological experiments, which supports the conclusion of rapid hydrolysis of the glycosidic bond of the substrate 4-Methylumbelliferyl-β-D-xylopyranoside 4-Methylumbelliferyl-β-D-xylopyranoside can be used for β- xylosidase activity studies.

Inhalation challenge with capsaicin and rapid intravenous injection of Lobelin and alinamin indicated that peripheral c-fiber receptors were involved in the induction of coughing.

Gibberllin A7 (Gibberllin 7) is important plant growth hormones that promote plant cell growth and elongation. Gebberillins promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates. The gibberellins are also involved in processes such as gravitropism, tensioning and floral display.Gibberellin A3 (G1025, G7645) and A4 (G7276) may be used as supplements to plant growth media such as Murashige and Skoog media. The specific actions of A3 and A4 or combinations of Gebberellins should be determined in specific plant applications.

Fusaproliferin is a diterpene mycotoxin identified in Fusarium solani. Fusaproliferin can reverse Lipopolysaccharides stimulation and the NF-κB and MAPKs signaling pathways, thus playing a role in anti-inflammatory processes. It has affinity for the TLR4 protein with a KD value of 28.6 μM. Fusaproliferin exhibits cytotoxicity against pancreatic cancer, showing rapid submicromolar IC50 effects.
