Ipratropium is a muscarinic receptor antagonist (IC50s = 2.9, 2, and 1.7 nM for M1, M2, and M3 receptors, respectively).{47807} It inhibits acetylcholine-induced bronchospasm in anesthetized guinea pigs (EC50 = 68 μg/ml). Aerosolized ipratropium (0.2 mg/20 ml) prevents increases in airway resistance in a rat model of cadmium inhalation-induced chronic pulmonary inflammation with airspace enlargement and reduces neutrophil counts and total cell numbers in bronchoalveolar lavage fluid (BALF) and airspace enlargement in lungs when administered in combination with formoterol (Item No. 15584).{47808} Formulations containing ipratropium have been used in the treatment of bronchospasm associated with chronic obstructive pulmonary disease.

  • 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}

    CAY10512 – 50 mg

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
