Adipogen
Description:
ZnAF-1F and ZnAF-2F do not fluoresce in the presence of other biologically important cations such as Ca2+ and Mg2+, and are insensitive to change of pH. The complexes with Zn2+ of previously developed ZnAFs, ZnAF-1, and ZnAF-2 decrease in fluorescence intensity below pH 7.0 owing to protonation of the phenolic hydroxyl group of fluorescein, whose pKa value is 6.2. On the other hand, the Zn2+ complexes of ZnAF-1F and ZnAF-2F emit stable fluorescence under neutral and slightly acidic conditions because the pKa values are shifted to 4.9 by substitution of electron-withdrawing fluorine at the ortho position of the phenolic hydroxyl group. Spectral data: lambdaex 492nm; lambdaem 517nm in PBS.

Adipogen
Description:
Cell permeable compound capable of slowing anaphase-promoting complex/cyclosome (APC/C)-dependent proteolysis. Inhibitor of the ubiquitin ligase activity of the APC/C by inhibiting substrate binding to Cdc20. Distinct mechanism of action than proTAME. Blocks mitotic exit only modestly when used alone in cultured cells. A strong synergistic effect is observed when Apcin and proTAME are used simultaneously, providing a more robust mitotic arrest. This may be very beneficial when treating cells that do not efficiently convert proTAME to its active parent compound (TAME) or if experiments demand strong APC/C inhibition.

Description:
Cell permeable, non-alkylating, non-thiol, adduct-forming, redox cycling quinone. Intracellular superoxide anion formation/ROS generation inducer. Anticancer agent. Shown to induce cell proliferation, apoptosis, necrosis and necroptosis in vitro, dependent on concentration, time, temperature and cell type. Valuable tool for the generation of reactive oxygen species (ROS) in order to study the role of ROS in cell toxicity, apoptosis and necrosis. Useful as reference compound in characterizing the effects of oxidative stress. Can be used to eliminate any mechanistic ambiguity involving redox cycling quinoids as the source of reactive oxidant species/oxidative stress in biological studies.

Description:
Close structural analog of the selective cyclooxygenase-2 (COX-2) inhibitor celecoxib, that lacks COX-2 inhibitory function. Anti-proliferative, anti-tumorigenic and anti-angiogenic. Potent apoptosis inducer in many cancer cell lines. Down-regulates the expression of survivin, cyclins, MMPs and inhibits cyclin-dependent kinase activity. Modulates PDK-1, AKT, GSK3beta, p70 S6K, PKA and MAPKAP-K1alpha. Reduces phosphorylation of ERK1/2 but not AKT T-308 or AKT S-473. Increases intracellular free calcium levels and potently triggers the endoplasmatic reticulum stress response (ESR), activating ER stress-associated proteins GRP78/BiP, CHOP/GADD153 and caspase-4.

Description:
Potent platinum-based antineoplastic agent. Anticancer compound. Forms inter- and intrastrand DNA adducts/crosslinks, consequently blocking DNA replication and transcription and inducing cell death. Nephrotoxic when used in vivo. Potent chemoimmunotherapeutic. Stimulates the immune responses by activating macrophages and other cells of the immune system. Apoptosis inducer via p53-dependent and -independent mechanisms. Induces apoptosis through caspase-3 activation and XIAP expression inhibition. Targets other proteins and enzymes. Non-competitive NHE-1 inhibitor, an archetypal, membrane-bound mechanosensitive sodium-hydrogen ion transporter.

Description:
Efficient coupling reagent for the synthesis of sterically hindered amides, especially peptides. In terms of reactivity and racemization-suppressing capability, this pyridinium-type reagent, BEP, proved to be more efficient than commonly used uronium- and phosphonium-type reagents, such as HBTU, BOP, and PyBroP, for the synthesis of hindered peptides containing N-methylated or Calpha,Calpha-dialkylated amino acid residues. BEP was also proven to be an efficient reagent for the synthesis of esters, especially active esters and hindered esters, and tert-butyl esters.

Description:
Metabolite. Oxidizing analog of N-acetyl-p-benzoquinone imine (NAPQI), a toxic metabolite of acetaminophen (paracetamol). Primarily oxidizes protein thiols. Shows cytotoxic properties, through disruption of intracellular Ca2+ homeostasis. Compound can be used as analytical reference material.

Description:
AS703026 is a novel, selective, non-competitive, orally bioavailable MEK1/2 inhibitor with experimental IC(50) values of 5-11nM. In use on multiple myeloma cells (MM), AS703026 inhibited growth and survival of MM cells and cytokine-induced osteoclast differentiation more potently (~10X) than AZD6244. Inhibition of proliferation induced by AS703026 was mediated by G0-G1 cell cycle arrest and was accompanied by reduction of MAF oncogene expression. AS703026 further induced apoptosis via caspase 3 and Poly ADP ribose polymerase (PARP) cleavage in MM cells, both in the presence or absence of bone marrow stromal cells (BMSCs). Importantly, AS703026 sensitized MM cells to a broad spectrum of conventional (dexamethasone, melphalan), novel or emerging (lenalidomide, perifosine, bortezomib, rapamycin) anti-MM therapies. Significant tumour growth reduction in AS703026- vs. vehicle-treated mice bearing H929 MM xenograft tumours correlated with downregulated pERK1/2, induced PARP cleavage, and decreased microvessels in vivo. Moreover, AS703026 (<lt/>200nM) was cytotoxic against the majority of tumour cells tested from patients with relapsed and refractory MM (84%), regardless of mutational status of RAS and BRAF genes. Importantly, BMSC-induced viability of MM patient cells was similarly blocked within the same dose range.
