(±)-Muscarine is an agonist of muscarinic acetylcholine receptors that was originally found in A. muscaria.{36535} It induces spasms in isolated intestinal ileum from mouse, guinea pig, rabbit, dog, monkey, and horse, contraction of longitudinal uterine and bladder muscle strips from mouse, guinea pig, rabbit, rat, horse, and dog, and slows the heart rate of isolated guinea pig and rabbit atria. In vivo, (±)-muscarine induces bronchoconstriction in guinea pigs and rabbits as well as respiratory depression in rabbits and cats with minimum active doses (MADs) ranging from 1 to 5 μg/kg. It reduces blood pressure in cats, dogs, and rabbits and induces uterine, bladder, and intestinal contraction in cats and dogs. (±)-Muscarine (0.005-0.01 mg/kg) increases circling and pacing behaviors and induces fear aggression in cats.{36536} It has antinociceptive activity in rats in the hot plate and tail-flick tests.{36537} (±)-Muscarine also inhibits acetylcholinesterase (Ki = 220 μM).{36538}

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

    Anhydrotetracycline (hydrochloride) – 50 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}
