Walrycin B is an antibiotic that has activity against Gram-positive bacteria (MICs = 0.39 and 3.13 μg/ml for B. subtilis and S. aureus, respectively) via inhibition of WalR, a response regulator that is essential to bacterial viability.{37399} It inhibits WalR-induced repression of EGFP signaling in a reporter assay in a concentration-dependent manner. Walrycin B alters expression of WalR regulon genes, decreasing ydjM, yocH, and ycvE and increasing yoeB and yjeA expression in B. subtilis. It also halts transcription of isaA and ssaA in S. aureus. Overexpression of WalR induces a 4- and 2-fold increase in the MIC against B. subtilis and S. aureus, respectively, indicating cell death is induced specifically through inhibition of WalR by walrycin B.

  • 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 – 25 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.
