Toltrazuril sulfone is an active metabolite of the coccidiostat toltrazuril (Item No. 20767).{46798} Toltrazuril sulfone is formed from toltrazuril via the intermediate metabolite toltrazuril sulfoxide by cytochrome P450 (CYP) enzymes, including CYP3A. It inhibits T. gondii tachyzoite production in African green monkey kidney cells when used at concentrations of 0.1, 1, and 5 µg/ml.{46799} Toltrazuril sulfone completely prevents infection with T. gondii tachyzoites in a mouse model of fatal toxoplasmosis when administered at doses of 10 or 20 mg/kg one day prior to, and daily for 10 days following, infection. It also reduces the number of infected mice in the same model when administered at a dose of 10 mg/kg for 11 days starting six days following infection. Formulations containing toltrazuril sulfone have been used in the treatment of equine protozoal myeloencephalitis (EPM) in horses.

  • A small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state; activity is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM

    SC-1 – 5 mg

    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.
