A potent, reversible inhibitor of ATM kinase (IC₅₀ = 6.3 nM), blocking the phosphorylation of ATM substrate proteins; sensitizes glioma cells to radiation and inhibits migration and invasion of glioma cells in vitro; produces radiosensitization and increases survival in vivo when...

A selective, reversible inhibitor of V-ATPases in mammalian, plant, or fungal cells.

A potent orally available inhibitor of Syk (Ki = 30 nM); blocks FcεRI-dependent mast cell activation (EC50 = 43 nM) and, at 3 μM, reduces the release of IL-10, -12, and -13 by immune complex-pulsed dendritic cells.

An analog of MAFP, which has been widely studied as an inhibitor of phospholipases, FAAH, and as a CB receptor ligand; pharmacology of the α-linolenyl analog of MAFP has not been completely investigated.

A PKCα and PKCβ1 inhibitor with IC₅₀ values of 2.3 and 6.2 nM, respectively; also inhibits the checkpoint kinases Chk1/2 and abrogates DNA damage-induced cell cycle arrest, leading to cytotoxicity in p53 mutant tumor cells.

A dehydration product of PGD2 formed by the elimination of the C-9 hydroxyl group; inhibits platelet aggregation (IC₅₀ ~ 5-10 nM); has antimitotic and antiproliferative effects on a variety of cultured normal cells and tumor cell lines.

Luteinizing hormone (LH) is a glycoprotein produced by the pituitary gland and consists of two subunits with a total molecular mass of approximately 30 kDa. The α-subunit is identical to the α-subunit of other pituitary hormones, such follicle stimulating hormone (FSH), thyroid...

An inhibitor of human recombinant PDE5 (IC₅₀ = 5.9 µM); used to treat erectile dysfunction and has been shown to have anti-cancer and antioxidant activity; induces differentiation of cardiomyocytes and increases the proliferation and differentiation of cultured human osteoblasts.

A synthetic phosopholipid that can be used for liposome production in order to study the properties of lipid bilayers.

An autoregulative inhibitor of spore germination in the genus Streptomyces at concentrations as low as 200 pM; also inhibits the porcine Na+/K+-activated ATPase (ID50 = 100 µM).

A selective nonpeptide allosteric, inverse agonist of CXCR2 (Kd = 2.51 nM); prevents neutrophil chemotaxis both in vitro and in a rat model of hyperoxia-induced lung injury.

A racemic mixture of the lactone form of the free acid, 8,12-iso- iPF2α-VI; the free acid is the most abundant F2-iP2 regioisomer measured in the urine of rats treated to induce lipid peroxidation; used as a biomarker for oxidative stress.

16-phenoxy PGF2α is a metabolically stable analog of PGF2α. It binds to the FP receptor on ovine luteal cells with much greater affinity (440%) than PGF2α.
