Orteronel is a non-steroidal inhibitor of the 17,20-lyase activity of the cytochrome P450 (CYP) isoform CYP17A1 (IC50s = 48 and 19 nM for the rat and human enzyme, respectively), which is the CYP17A1 activity that converts progestogens into androgens.{39593} Orteronel is selective for the 17,20-lyase activity of CYP17A1 over its 11-hydroxylase activity and CYP3A4 (IC50s = >1,000 and >10,000 nM, respectively). It decreases adrenocorticotropic hormone-induced production of DHEA, androstenedione, cortisol, and aldosterone in monkey adrenal cells (IC50s = 110, 130, 310, and 4,400 nmol/L, respectively) and inhibits DHEA production in NCI-H295R human adrenocortical tumor cells.{39594} A single oral dose of orteronel (0.3-10 mg/kg) dose-dependently decreases DHEA, cortisol, and testosterone levels in the plasma of intact cynomolgus monkeys for at least 10 hours, and chronic dosing of 15 mg/kg twice daily suppresses levels for up to seven days of treatment. It also decreases DHEA and testosterone plasma levels in castrated monkeys, indicating an effect on extra-gonadal production of testosterone.

    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 – 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}
