The sirtuins represent a distinct class of trichostatin A-insensitive lysyl-deacetylases (class III HDACs) and have been shown to catalyze a reaction that couples lysine deacetylation to the formation of nicotinamide and O-acetyl-ADP-ribose from NAD+ and the abstracted acetyl group. There are seven human sirtuins,...

The leukotriene B4 receptor 1 (BLT1 receptor), cloned from HL-60 human leukemia cells, has 352 amino acids and seven putative membrane-spanning domains. The primary structure of the receptor is identical to that of a putative purinoceptor, P2Y7, which binds to micromolar concentrations of ATP. Northern blotting...

1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA is a phospholipid containing arachidonic acid at the sn-1 position. It has been found in rat brain as 37% of the arachidonic acid-containing lysophosphatidic acid (LPA) species and is a precursor to 1-arachidonoyl glycerol (1-AG, Cay-62150)....

Elesclomol is an inducer of apoptosis and a copper ionophore. It induces the production of reactive oxygen species (ROS) and increases oxidative stress response gene expression in Ramos (RA 1) B cell lymphoma cells when used at a concentration of 500 nM. Elesclomol (100 nM) disrupts the mitochondrial membrane...

Terbinafine is a broad-spectrum antifungal agent that has activity against T. rubrum, T. metagrophytes, T. verrucosum, E. floccosum, M. canis, A. fumigatus, and S. schenckii (MIC50s = 0.003-0.8 µg/ml). It selectively inhibits C. albicans squalene epoxidase over rat liver epoxidase (IC50s = 0.03 and 77 µM,...
