2-Hydroxy-4-methoxybenzaldehyde is a phenol found in the root bark essential oil of P. sepium that has diverse biological activities, including antibacterial, antifungal, fungicidal, antioxidant, anti-virulence, and metal chelating properties.{55018,55019,55020} It is active against Gram-positive (MICs = 100-200 µg/ml) and Gram-negative bacteria (MICs = 125-200 µg/ml), as well as the fungus C. albicans and the phytopathogenic fungus M. oryzae (MICs = 150 and 300 µg/ml, respectively). 2-Hydroxy-4-methoxybenzaldehyde scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals in a cell-free assay (IC50 = 9.04 mg/ml) and acts as a metal chelator, inhibiting ferrozine-Fe2+ complex formation with an IC50 value of 2.31 mg/ml. It reduces the production of the virulence factor staphyloxanthin in clinical isolates of methicillin-resistant S. aureus (MRSA) when used at a concentration of 200 µg/ml and decreases the expression of the MRSA virulence regulatory genes saeS, geh, crtM, and sigB.{55019} 2-Hydroxy-4-methoxybenzaldehyde, when used in combination with the antibiotics amikacin (Item No. 15405), gentamicin, cefotaxime (Item No. 16040), vancomycin (Item No. 15327), or tetracycline (Item No. 14328), increases MRSA antibiotic sensitivity. It is also an intermediate in the synthesis of Schiff base-metal complexes with antiproliferative activity.{55020}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 50 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.
