Zardaverine is a dual inhibitor of phosphodiesterase 3 (PDE3) and PDE4 (IC50s = 0.617 and 1.738 μM, respectively, for the rat cardiac ventricle enzymes).{46697} It is selective for PDE3 and PDE4 over PDE1B, PDE2, and PDE5 (IC50s = >138 μM for all). Zardaverine inhibits aggregation of human platelets induced by ADP (Item No. 21121), platelet-activating factor (PAF), collagen, arachidonic acid (Item Nos. 90010 | 90010.1 | 10006607), or prostaglandin E1 (PGE1; Item No. 13010) and ADP (IC50s = 1.5-16.2 μM). It inhibits zymosan-induced superoxide anion release from human polymorphonuclear (PMN) cells (IC50 = 0.4 μM). Zardaverine (10 μmol/kg) decreases lung resistance and increases dynamic compliance in a rat model of acetylcholine-induced bronchospasm.{46698} It decreases the viability of HeLa, COLO 741, NCI H2122, and A2058 cells that endogenously express high levels of PDE3A (IC50s = 0.032, 0.027, 0.26, and 0.13 μM, respectively), but is inactive against a panel of eight cancer cell lines that express low levels of PDE3A (IC50s = >16 μM for all).{46699}

    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}

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

    Anhydrotetracycline (hydrochloride) – 100 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}
