7-Ethoxyresorufin (7-ER) is a fluorogenic substrate for, and competitive inhibitor of, the cytochrome P450 (CYP) isoform CYP1A1 (IC50 = 0.1 µM).{26089,26092,26091} Upon enzymatic cleavage by CYP1A1, resorufin is released and its fluorescence can be used to quantify CYP1A1 activity. Resorufin displays excitation/emission maxima of 570/580 nm, respectively.{50356} 7-ER has been used in the study of arachidonic acid (Item Nos. 90010 | 90010.1 | 10006607) metabolism and the mechanisms of vasodilation.{15972,12467} 7-ER is a noncompetitive inhibitor of neuronal nitric oxide synthase (nNOS; Ki = 0.76 µM).{26088,26090}

  • 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 – 1 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.

    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}
