Ramelteon is a melatonin (MT) receptor agonist (Kis = 14, 112, and 23.1 pM for human MT1, human MT2, and chick forebrain receptors, respectively).{42292} It is selective for MT1 and MT2 over MT3 receptors (Ki = 2.65 μM for hamster brain MT3 receptors) as well as a panel of benzodiazepine, dopamine, and opiate receptors, ion channels, transporters, and enzymes when used at a concentration of 10 μM. Ramelteon stimulates cAMP production in CHO cells expressing human MT1 and MT2 receptors (IC50s = 21.2 and 53.4 pM, respectively). In vivo, ramelteon (0.03 and 0.3 mg/kg, p.o.) shortens latency to sleep onset and increases duration of sleep in free-moving crab-eating macaques.{42293} It also accelerates reentrainment of circadian rhythm in rats, shifting running wheel activity back to the dark period 2.4 and 3 days more quickly than vehicle-treated animals following an eight-hour phase shift in the light-dark cycle when administered at 0.1 and 1 mg/kg, respectively, with no effect on learinng and memory in the Morris water maze and delayed match-to-position tasks.{42294}

  • 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}
