Asapiprant is an antagonist of the prostaglandin D1 (PGD1) receptor (DP1; Ki = 0.44 nM).{50862} It is selective for DP1 over DP2, as well as the thromboxane A2 (TXA2), prostaglandin I2 (PGI2), and prostaglandin E1-4 (PGE1-4) receptors (Kis = >5,000, >4,800, >6,300, and 120->6,600 nM, respectively). Asapiprant (1 and 3 mg/kg) reduces PGD2-induced increases in nasal resistance in a guinea model of allergic rhinitis. It reduces nasal secretion, when administered at doses of 3 and 30 mg/kg, and antigen-induced cell infiltration in nasal lavage fluids, when administered at 3 and 10 mg/kg, in a guinea pig model of allergic rhinitis induced by ovalbumin. Asapiprant (10 mg/kg) also decreases airway hyperresponsiveness, inflammatory cell infiltration in bronchoalveolar lavage fluid (BALF), and mucin production in a rat model of ovalbumin-induced asthma.

    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.

  • 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}
