Highly selective COX-2 inhibitor (IC₅₀ 50 >500 µM (COX-1).

An antagonist of PPARα (IC50 = 240 nM), promoting the recruitment of co-repressor proteins; used in cell-free, cell lysate, and whole cell systems.

A precursor of coenzyme Q10 that has 2, rather than 10, isoprenoid units on the ubiquinone base.

A 4-demethoxy analog of daunorubicin which intercalates in DNA and inhibits topoisomerase II, resulting in cancer cell cytotoxicity at low concentrations (IC₅₀ = 20-120 nM); effective in combination therapy for the treatment of different types of leukemia.

A fluorescent probe used for measuring membrane fluidity in artificial and living membrane systems.

A more lipid soluble form of (+)-cloprostenol, possibly serving as a prodrug for the bioactive free acid.

An analog of GlcNAc that reversibly inhibits NCOAT (O-GlcNAcase).

A natural compound with strong antioxidant activity; potently inhibits the release of TNF-α (IC50 = 0.09 nM) and IL-4 (IC50 = 2.8 nM), as well as β-hexosaminidase and CCL2 (MCP-1) from IgE-stimulated RBL-2H3 mast cells.

An irreversible EGFR tyrosine kinase inhibitor that blocks ATP-dependent autophosphorylation of EGFR carrying the T790M mutation as well as an L858R mutation (IC₅₀ = 8 nM); effective in mouse models of lung cancer driven by EGFRT790M.

(–)-Ropivacaine-d7 is intended for use as an internal standard for the quantification of (–)-ropivacaine (Item No. 21422) by GC- or LC-MS. (–)-Ropivacaine is a potent and reversible blocker of sodium channels in nerve fibers.{33665} In vivo, (–)-ropivacaine induces complete impairment of...

A long-acting muscarinic receptor antagonist that binds equally to human muscarinic M1, M2, and M3 receptors (Kds = 0.04, 0.02, and 0.01 nM, respectively); dissociates slowly from M1 and M3 receptors, which are located on bronchial smooth muscle and submucosal glands, and more rapidly from M2...

Antigen: a portion of the NF-κB (p65) NLS Host: rabbit Cross-reactivity: (+) bovine, chimpanzee, gorilla, equine, human, monkey, and mouse NF-κB (p65) Application(s): ICC and WB p65 is a part of the NF-κB (p50/p65) heterodimer. IκB interacts with NF-κB dimers and...

A synthetic intermediate useful for pharmaceutical synthesis.

A glycopeptide antibiotic identified for its utility in the treatment of gram-positive bacteria, including penicillin-resistant staphylococci; binds to bacterial cell wall precursors, interfering with their synthesis.

An analytical reference standard categorized as a phytocannabinoid metabolite; a metabolite of ?8-THC; intended for research and forensic applications

A dietary flavonoid which has diverse physiological activities through both direct and indirect effects; directly binds ERα and ERβ, acting as an inverse agonist or agonist; acts as an antioxidant; suppresses signaling through certain receptor tyrosine kinases, including EGFR and HGF.

Source: Recombinant N-terminal GST-tagged enzyme expressed in E. coli MW: 61.9 kDa SIRT4 is a mitochondrial ADP-ribosyltransferase responsible for the transfer of ADP-ribose from NAD to specific substrates such as glutamate dehydrogenase.

12(S)-HpEPE is a monohydroperoxy PUFA produced by the action of 12-LO on EPA. Although the biological activities of 12(S)-HpEPE have not been well characterized, it is expected to behave similarly to 12(S)-HpETE.

Tamoxifen-d₅ contains five deuterium atoms at the 3, 3, 4, 4, and 4 positions. It is intended for use as an internal standard for the quantification of tamoxifen (Item No. 13258) by GC- or LC-MS. Tamoxifen is a selective estrogen receptor (ER) modulator, evoking tissue-dependent effects....

An acyclic nucleoside phosphonate that acts as a reverse transcriptase inhibitor; demonstrates antiviral activity against herpes viruses, hepatitis B virus, and HIV in animal and clinical models of infections.
