Tetranactin is a macrotetrolide and a monovalent cation ionophore that has been found in S. aureus and has antibacterial, insecticidal, and mitogenic activities.{42589,42590} It exhibits an equilibrium permeability ratio 1,000-fold greater for lithium than sodium or cesium ions accross bilayer membranes at low voltages.{42590} Tetranactin inhibits the growth of Gram-positive bacteria and C. miyabeanus and R. solani fungi when used at concentrations less than 0.9 μg/ml.{42589} Tetranactin (0.5-1.5 μg per insect) dose-dependently increases the mortality of adult C. chinensis weevils up to 100% and has mitogenic activity against T. telarius when sprayed onto plants with an LC50 value of 9.2 μg/ml. It reduces IL-1β- and cAMP-induced secretion of phospholipase A2 (PLA2) from rat mesangial cells (IC50s = 43 and 33 nM, respectively).{42591} Tetranactin (50 ng/ml) suppresses the proliferation of human T lymphocytes induced by allogeneic cells and IL-2 and supresses the generation of cytotoxic T lymphocytes in mixed lymphocyte cultures.{42592} In vivo, tetranactin (10 mg/animal per day) completely inhibits the formation of experimental autoimmune uveoretinitis (EAU) in rats.{42593}

Description

A monovalent cation ionophore; exhibits an equilibrium permeability ratio 1,000-fold greater for lithium than sodium or cesium accross bilayer membranes at low voltages; inhibits the growth of twelve Gram-positive bacteria strains and C. miyabeanus and R. solani fungi on agar plates at C. chinensis weevils from 0.5-1.5 μg per insect; has mitogenic activity against T. telarius (LC50 = 9.2 μg/ml); reduces IL-1β- and cAMP-induced secretion of PLA2 from rat mesangial cells (IC50s = 43 and 33 nM, respectively); suppresses the proliferation of human T lymphocytes induced by allogeneic cells and IL-2 at 50 ng/ml; completely inhibits the formation of EAU in rats at 10 mg/animal/day ,

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal.

    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}
