A 5-fluorotryptamine derivative that inhibits myeloperoxidase/MPO activity (IC50 = 18nM) via direct affinity interaction with enzyme active site heme pyrrole ring D, while exhibiting much reduced affinity toward serotonin reuptake transporter/SERT (Ki = 631nM). Kinetic studies reveal that the inhibitor acts as a good one-electron donor for the intermediate Compound I "Fe(IV)=O.Por +", facilitating the formation of Compound II (Fe(IV)-OH.Por) and thereby preventing the reduction of Compound I directly to the resting state "Fe(IV).Por" via the "halogenation cycle", while, on the other hand, behaves as a poor electron donor for Compound II, thereby preventing the completion of the "peroxidase cycle" by stalling the further reduction of Compound II to the resting state.

Similar selectivity is observed in whole-cell HEK patch-clamp assays with IC50 values for GluN2C and GluN2D that are at least 50-fold lower than those for recombinant GluN2A, GluN2B, GluA1, or GluK2-containing receptors. It inhibits NMDA by blocking a conformational change necessary for channel opening and is non-competitive with co-agonists, glutamate and glycine. Group: Biochemicals. Grades: Highly Purified.

Novel Inducer of Death-1, NID-1 ((E)-N-(2-ethylphenyl)-3-(5-nitrothiophen-2-yl)acrylamide)
A cell-permeable, nitrothiophenyl propenamide compound that induces active, energy-dependent, and rapid non-apoptotic cell death (EC50 = 1.65uM) in several transformed (DRD, RKO, H1299) and non-transformed (BJeH) human cells, in a variety of cancer cell lines, and in mouse embryonic fibroblasts. The cell death appears to be non-necrotic, non-oxidative and is independent of DNA damage or cell proliferation. NID-1 induced cell death, although distinct from macroautophagy, does show PI 3-kinase suppression, ATG5-dependence, p62 degradation, and higher LC3 levels. Also, NID-1-induced death is independent of caspases, Bax and Bak and requires lysosomal activity and cytosolic vacuolization. Rescues mutant-huntingtin-induced cell death in a cell-based model of Huntingtons disease. Shown to increase cathepsin L levels, but does not affect cathepsins B, C, and H. Group: Biochemicals.

Nrf2 Activator II, AI-1 (Ethyl-4-chloro-1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxylate)
A cell-permeable chloro-quinolinone compound that selectively and covalently modifies Kelch-like ECH-associated protein 1 (Keap1)-Cys151 and represses Keap1 function and reduces Nrf2 (Nuclear factor E2-related factor 2)-Keap1 interaction. Shown to stabilize Nrf2 by inhibiting the Keap1-driven ubiquitination of Nrf2 and thereby activating the Nrf2-ARE (antioxidant response element) pathway (EC50 = 2.7uM in neuroblastoma IMR-32 cells). Offers protection against H2O2 induced oxidative stress, but unlike tert-butylhydroquinone AI-1 does not act as a free radical scavenger. Its anti-oxidant effects are mediated via Nrf2 induced antioxidant response. Does not affect mutant ARE where GC are substituted with AT within the core ARE sequence. Group: Biochemicals.

A 14-mer peptide (LQLDEETGEFLPIQ) conjugated to cell-penetrating trans-activating transcriptional activator (TAT) sequence (YGRKKRRQRRRLQ) that targets the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) binding site on Kelch-like ECH-associated protein 1 (Keap1). Competitively disrupts Nrf2-Keap1 interaction and stabilizes cytosolic Nrf2, and promotes its nuclear translocation and binding to the antioxidant response element (ARE). Exhibits anti-inflammatory properties and increases heme-oxygenase-1 gene expression (~75uM). Also shown to suppress LPS-induced TNF-a secretion in THP-1 monocytes (~ 37.5uM). Group: Biochemicals.

Exhibits cognitive enhancing effects in vivo. Group: Biochemicals. Grades: Highly Purified. CAS No. 501684-93-1. Pack Sizes: 10mg. US Biological Life Sciences.
An aminobenzimidazole derivative that selectively and reversibly blocks small conductance Ca2+-activated K+ channels (SK1-3; =420nM, 600nM, and 730nM for SK1, SK2, SK3, respectively) in a Ca2+-dependent manner. It mediates channel gating by interacting with gating structures deep within the inner pore vestibule where Ser507 and Ala532 are deemed to be important for inhibition. Interacts at a site that is distinct from the apamin binding site in SK channels. Can access high-affinity binding sites from both the inside and outside of the cell membrane. Does not affect QT intervals, but prolongs the atrial effective refractive period and prevents acetylcholine-induced atrial fibrillations in ex vivo and in vivo models. Also shown to reversibly block TRPM7 channel (IC50=1.6mM) in smooth muscle cells, primary podocytes, HEK293 cells expressing TRPM7, and ventricular myocytes in a Mg2+-dependent manner and blocks the motility of cells in culture.

A cell-permeable phenylacetate compound that blocks Nur77 (TR3) LKB1 nuclear-sequestering function by antagonizing against Nur77-LKB1 interaction via direct binding at the LKB1 LBD/ligand binding domain (Kd = 0.14 against 5uM LKB1 binding to 5uM full-length Nur77). Shown to induce LKB1 Ser428 phosphorylation (10 & 20uM for 6h) and LKB1 nuclear-to-cytosol translocation in hepatic LO2 cells, resulting in enhanced phosphorylations of LKB1 cytosolic effectors AMPKalpha and MARK1/2/3 without affecting Nur77 transactivation activity. Daily i.p. dosing (50mg/kg) is shown to increase liver LKB1 Ser428/AMPKalpha Thr172 phosphorylations in diabetic db/db mice in vivo, effectively improving animal glucose tolerance. Also reported to lower fasting blood glucose level in STZ-treated, high fat diet-fed type II diabetic mice. Group: Biochemicals. Grades: Highly Purified. Pack Sizes: 10mg.
