The prostaglandin E2 (PGE2) receptor EP1 is involved in triggering PGE2-mediated pain, neuronal survival and growth as well as the suppression of tumor metastasis. SC-19220 is a dibenzoxazepine that acts as a selective antagonist of PGE2 at the EP1 receptor.{6742,2681} At doses between 0.3-300 µM, SC-19220 acts as a competitive antagonist of PGE2-induced smooth muscle contractions of guinea pig ileum and stomach.{6911,6856} SC-19220 also acts as a PGE2 antagonist in the EP1 receptor-mediated contraction of guinea pig trachea.{6294} SC-19220 displaces radiolabeled PGE2 from the cloned human EP1 receptor with an IC50 of 6.7 µM and exhibits no binding at the human EP2 receptor.{3176,3186} It binds with apparent low affinity to the cloned mouse EP1 receptor expressed in CHO cells.{6640} In a model of bone resorption, 3-150 μM SC-19220 inhibited both 1,25 dihydroxy vitamin D3- and PGE2-stimulated osteoclastogenesis in mouse osteoclast precursors.{23818} Antagonism of EP1 with 1 μM SC-19220 has been shown to promote metastasis in a mouse model of metastatic breast cancer.{18890} In a rodent model of Parkinson’s disease, 1.5 μM SC-19220 prevented PGE2-mediated loss of dopaminergic neurons from rat substantia nigra.{15975}

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells.

  • 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}
