Cyclo(L-His-L-Pro) is an endogenous cyclic neuropeptide and a metabolite of thyrotropin-releasing hormone (TRH).{57272} It is formed in the hypothalamus via the hydrolytic removal of pyroglutamic acid from TRH followed by non-enzymatic cyclization but is also synthesized de novo.{57273} It is ubiquitously expressed in the CNS, but is also found in the gastrointestinal tract and blood. Cyclo(L-His-L-Pro) (50 µM) reduces LPS-induced production of reactive oxygen species (ROS) and nitric oxide (NO), as well translocation of NF-κB in BV-2 microglia. Levels of cyclo(L-His-L-Pro) are increased in rat brain after six weeks of continuous ethanol consumption and cyclo(L-His-L-Pro) reduces ethanol-induced sleep time in rats when administered at a dose of 1 µmol/kg.{57272,57274} Cyclo(L-His-L-Pro) induces analgesia in the hot-plate test and reduces acetic acid-induced writhing in mice, effects that can be partially reversed by the opioid antagonist naloxone.{57272}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 25 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) – 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}

  • A potent inhibitor of Cdk2/cyclin E with an IC50 value of 0.1 µM; also inhibits Cdk7/cyclin H

    (R)-Roscovitine – 5 mg

    Cyclin-dependent kinases (CDKs) are key regulators of cell cycle progression and are therefore promising targets for cancer therapy. (R)-Roscovitine is a potent inhibitor of Cdk2/cyclin E with an IC50 value of 0.1 µM.{14988} It also inhibits Cdk7/cyclin H, Cdk5/p35, and cell division cycle (cdc)/cyclin B with IC50 values of 0.49, 0.16, and 0.65 µM, respectively.{14987,14988,14991} (R)-Roscovitine inhibits the growth of rapidly proliferating cells with an average IC50 value of 15.2 µM against a panel of 19 human tumor cell lines.{14988} In murine models of polycystic kidney disease, (R)-roscovitine effectively inhibited disease progression at doses of 50-100 mg/kg.{14564}
