Arenobufagin is a cardiotonic steroid that has been found in the skin secretions of the toad B. gargarizans and has anticancer activity.{52655,52656,42766,52657} It inhibits Na+/K+-ATPase activity in isolated guinea pig ventricular myocytes with an IC50 value of 290 nM.{52655} Arenobufagin (20-500 nM) induces cleavage of poly(ADP-ribose) polymerase (PARP), caspase-3, and caspase-9, as well as induces apoptosis in HepG2 hepatocellular carcinoma cells.{52656} It inhibits proliferation of HepG2, Hep3B, BEL-7402, and MCF-7 cancer cells (IC50s = 101.9, 39.8, 416.3, and 143.7 nM, respectively), as well as multidrug-resistant HepG2/adm and MCF-7/adr cancer cells (IC50s = 730 and 67.5 nM, respectively). Arenobufagin (1 mg/kg once per day, i.v.) reduces tumor growth, the number and size of lung metastases, and tumor levels of the epithelial-to-mesenchymal transition (EMT) markers vimentin and β-catenin in a PC3 mouse xenograft model.{42766} Arenobufagin (5 and 10 µM/plug) inhibits VEGF-induced angiogenesis in a Matrigel™ plug assay in mice.{52657}

  • 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}

    (R)-Roscovitine – 10 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}
