An inhibitor of p53-HDM-2 interaction that can reactivate the tumor suppressor function of wild-type p53; binds to p53 with an apparent Kd value of 1.5 nM and prevents interaction with HDM-2 resulting in p53 stabilization

HDM-2 (human double minute-2; MDM-2 in mouse) is a key negative regulator of p53 that binds to and targets p53 for proteasomal degradation. Overexpression of HDM-2 in some tumors leads to inactivation of p53 thereby allowing tumor cells to escape p53-induced apoptosis.{13684} RITA (reactivation of p53 and induction of tumor cell apoptosis) is a small molecule inhibitor of p53-HDM-2 interaction that can reactivate the tumor suppressor function of wild-type p53.{12386} It binds to p53 with an apparent Kd of 1.5 nM and prevents interaction with HDM-2 resulting in p53 stabilization, accumulation and activation.{12386} RITA potently inhibits the growth of a variety of cancer cell lines in the sub-micromolar range, inducing both DNA-protein and DNA-DNA cross links in human renal cancer cells.{13683} RITA reduced tumor size by 90% at a dose of 10 mg/kg in SCID mice bearing HCT116 tumors, and caused complete regression of A-498 tumor cell xenografts in nude mice at a dose of 45 mg/kg.{12386,13682}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 25 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.
