BAR501 is a selective agonist of the G protein-coupled bile acid-activated receptor (GP-BAR1; EC50 = 1 μM) that lacks activity at the farnesoid X receptor (FXR).{36072} In vivo, BAR501 reduces hepatic perfusion pressure and counteracts norepinephrine-induced vasoconstriction in naïve rats. It protects against development of endothelial dysfunction by increasing liver cystathione-γ-liase (CSE) expression and activity, while reducing endothelin 1 (ET-1) gene expression in a rat model of cirrhosis. In vitro, BAR501 increases Akt-dependent phosphorylation of CSE and endothelial nitric oxide synthase (eNOS) and inhibits ET-1 transcription in human liver sinusoidal cells. BAR501 also shifts macrophages from the inflammatory (M1) phenotype to the anti-inflammatory (M2) phenotype and reduces trinitrobenzenesulfonic acid-induced colitis in mice in a dose-dependent manner.{36071}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 10 µg

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

  • 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 – 10 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.
