Deferasirox-d4 is intended for use as an internal standard for the quantification of deferasirox (Item No. 16753) by GC- or LC-MS. Deferasirox is a synthetic, tridentate iron chelator that binds iron at a 2:1 ratio.{36858} It is selective for iron (Fe(III)) over Cu(II), Zn(II), Mg(II), and Ca(II) but does bind to Al(III). Deferasirox decreases iron levels in iron-loaded rat heart cells in vitro by 45.8 and 55.6% compared to control levels when used at concentrations of 160 and 320 µM, respectively.{27434} In hypertransfused rats, deferasirox (200 mg/kg) decreases radiolabeled liver iron levels from 41 to 21.7% and blood iron levels from 8.2 to 3.4%.{27434} It is primarily excreted via the fecal route, in contrast to the iron chelator deferoxamine (Item No. 14595).{27434} Deferasirox also inhibits proliferation of SAS human oral squamous carcinoma cells (EC50 = 21 µM), decreases cyclin D1 protein levels, and increases protein levels of N-Myc downregulated gene 1 (NDRG1) and NDRG3.{38960} It acts in a synergistic manner when used in combination with gemcitabine (Item Nos. 11690 | 9003096) to reduce proliferation of BxPC-3 pancreatic cancer cells in vitro and reduce tumor growth in a BxPC-3 mouse xenograft model when administered at a dose of 200 mg/kg.{36859} Formulations containing deferasirox have been used in the treatment of β-thalassemia and chronic iron overload.

    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 – 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.
