Zotarolimus is a macrocyclic lactone immunosuppressant and a derivative of rapamycin (Item No. 13346).{48775,48776} It binds to FKBP prolyl isomerase 1A (FKBP12; IC50 = 2.57 nM) and inhibits proliferation of human peripheral blood mononuclear cells (PBMCs), rat splenocytes, and human coronary artery smooth muscle cells (IC50s = 7, 1,337, and 0.8 nM, respectively).{48776} Zotarolimus has immunosuppressive activity in a one-way mixed lymphocyte reaction using human or rat lymphocytes (IC50s = 1.2 and 1,465 nM, respectively). It also reduces symptom severity in a rat model of experimental autoimmune encephalomyelitis (EAE; ED50 = 1.17 mg/kg per day) and delays cardiac allograft rejection in rats (ED50 = 3.71 mg/kg per day). Zotarolimus inhibits neointimal formation and reduces stenosis in pig coronary arteries when applied at 10 µg/mm to stainless steel balloon expandable stents with phosphorylcholine in a model of restenosis.{48775} Formulations containing zotarolimus have been used in drug-eluting stents in the prevention of restenosis following stent placement.

    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.

  • 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}
