Zatebradine is a bradycardic compound that blocks hyperpolarization-activated inward current (If) through cyclic nucleotide-gated cation (HCN) channels in sinoatrial node cells (IC50s = 1.83, 2.21, 1.9, and 1.88 µM, respectively for HCN1-4 in vitro).{30118,25789} Additionally, it can block voltage-gated outward K+ (IK) currents and related neuronal hyperpolarization-activated inward current (Ih) channels, but exhibits little or no activity for L-type Ca2+ (ICa) currents.{30117,28049} When assessed through telemetric ECG recording in mice, zatebradine reduced heart rate from 600 to 200 beats per minute with an ED50 value of 1.8 mg/kg and induced increasing arrhythmia at concentrations >10 mg/kg.{30118}

  • 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}
