2-Nonylquinolin-4(1H)-one is a quinolone alkaloid that has been found in P. aeruginosa and has diverse biological activities.{58183,58184,58185,58188} It reduces infection of Huh7.5 cells by hepatitis C virus (HCV) with an IC50 value of 1.4 µg/ml.{58183} 2-Nonylquinolin-4(1H)-one (50 and 100 µg/ml) is also active against L. gongylophorus, a symbiotic fungus of the agricultural pest A. sexdens (leaf-cutting ant).{58184} It inhibits activation of nuclear factor of activated T cells (NFAT) induced by phorbol 12-myristate 13-acetate (TPA; Item No. 10008014) and the calcium ionophore A23187 (Item No. 11016) in Jurkat cells (IC50 = 3.44 µM), but not LPS-induced NF-κB activation in RAW 264.7 cells (IC50 = >100 µM), in reporter assays.{58185} This compound is expected to exist in one or both tautomeric forms, depending on experimental conditions.

The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

1,2-Dipalmitoyl-sn-glycero-3-PC (DPPC) is a zwitterionic glycerophospholipid commonly used in the formation of lipid monolayers, bilayers, and liposomes for use in a variety of applications.{14480,24261,14478,14479} It has been used in the formation of proteoliposomes for implantation of γ-glutamyl transpeptidase into human erythrocyte membranes.{14478} Incorporation of glycosphingolipid antigens into DPPC-containing liposomes increases the immunogenicity of the antigens in mice.{14479}

The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
