Y-26763 is an activator of ATP-sensitive potassium (KATP) channels.{50363} It increases the frequency of KATP channel openings in the presence of ATP and activates KATP channel currents in isolated human β-cells when used at a concentration of 200 μM. It also inhibits increases in intracellular calcium induced by histamine or norepinephrine (Item No. 16673) in isolated rabbit mesenteric artery smooth muscle in a concentration-dependent manner.{50364} Y-26763 induces relaxation in isolated precontracted rat aortic rings (IC50 = 0.027 μM).{50365} It decreases mean blood pressure in spontaneously hypertensive rats when administered intravenously at a dose of 0.03 mg/kg, an effect that can be reversed by glibenclamide (Item No. 15009).

  • 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. SC-1 is 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.{14533} The activity of SC-1 is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM, respectively.{14533} Inhibition of RasGAP increases Ras signaling via the PI3-kinase pathway which promotes self-renewal, whereas inhibition of ERK blocks differentiation.
