8-Cyclopentyl-1,3-dimethylxanthine (CPT) is an adenosine A1 receptor antagonist (Ki = 10.9 nM).{48947} It is selective for adenosine A1 over A2 receptors (Ki = 1,440 nM). CPT inhibits hypoxia-induced depression of evoked synaptic potentials in rat hippocampal slices in a concentration-dependent manner.{48948} It increases secondary after-discharge duration in electrically induced seizures in rats when administered at doses of 2.5 mg/kg or higher.{48949} CPT increases the response rate under a fixed-interval schedule of stimulus-shock termination in squirrel monkeys (ED50 = 2.5 μmol/kg), indicating psychomotor stimulant effects.{48950}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 50 mg

    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}

    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.
