(R)-Cetirizine is the (R)-enantiomer of the histamine H1 receptor antagonist and second generation antihistamine cetirizine (Item No. 19686).{31604} (R)-Cetirizine binds to the H1 receptor with higher affinity than cetirizine (Kis = 3 and 6 nM, respectively) and is 25,000-100,000-fold selective for H1 receptors over muscarinic M1-M5 receptors.{39482} It decreases production of RANTES and eotaxin following antigen stimulation in mouse eosinophils in vitro in a concentration-dependent manner with a minimum effective concentration (MEC) of 0.05 µM.{39483} Intranasal administration of (R)-cetirizine (0.01-1%) dose-dependently decreases histamine-induced nasal rubbing and sneezing in mice.{39484} Formulations containing (R)-cetirizine have been used in the treatment of allergic rhinitis and chronic idiopathic urticaria.

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 50 µg

    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.

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

    Anhydrotetracycline (hydrochloride) – 250 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}
