Gamma-glutamylcysteine (Standard) is the analytical standard of Gamma-glutamylcysteine. This product is intended for research and analytical applications. Gamma-glutamylcysteine (γ-Glu-Cys) is an orally active, blood-brain barrier permeable dipeptide. Gamma-glutamylcysteine activates AMPK, SIRT1, IL-4/STAT6, AC/cAMP/PI3K, IGF-1R/IRS1/PI3K, and Nrf2 signaling pathways; it inhibits NF-κB, JAK1/STAT1/3, MAPKs, cadmium-induced p38 MAPK, JNK, and PI3K/Akt signaling pathways. Gamma-glutamylcysteine regulates macrophage polarization, modulates the trafficking of CD36 and GLUT4, induces glutathione synthesis, improves metabolic dysfunction, reduces lipid deposition, ameliorates glucose homeostasis, inhibits apoptosis (Apoptosis), stabilizes mitochondria, suppresses lipid peroxidation, iron accumulation and ferroptosis (Ferroptosis), reduces ds-HMGB1 levels, reverses mechanical hyperalgesia, and alleviates hepatic lipid droplet formation. Gamma-glutamylcysteine is applicable to research related to inflammatory bowel disease, type 2 diabetes, cadmium-induced neurotoxicity, Alzheimer's disease, cerebral ischemia/reperfusion injury, neuropathy, and alcoholic liver disease.

Arjunolic acid is an orally active, multifunctional bioactive compound. Arjunolic acid exhibits free radical scavenging activity, as well as fungal and bacterial activities. Arjunolic acid induces apoptosis (Apoptosis) in various cancer cells. Arjunolic acid protects hepatocytes against induced oxidative stress and apoptosis by reducing reactive oxygen species and inhibiting NF-κB activation. Arjunolic acid regulates pancreatic dysfunction in type 2 diabetic rats by blocking the activation of the TLR-4/MyD88 and canonical Wnt pathways. Arjunolic acid inhibits neuroinflammation and ameliorates depressive behaviors via the SIRT1/AMPK/Notch1 signaling pathway in microglia. Arjunolic acid improves Crohn's disease-like colitis by restoring gut microbiota composition and inhibiting TLR4 signaling. Arjunolic acid suppresses osteosarcoma progression by inhibiting Wnt3a-mediated M2 polarization of macrophages. Arjunolic acid ameliorates diabetic retinopathy via the autophagy pathway regulated by AMPK/mTOR/HO-1. Arjunolic acid is applicable to research related to type 2 diabetes, organ toxicity, depression, Crohn's disease, osteosarcoma, diabetic retinopathy, and testicular dysfunction.

Myricanol is a diarylheptanoid and a Nampt activator. Myricanol exerts anti-inflammatory effects and alleviates glucocorticoid-induced muscle atrophy by increasing Sirtuin 1 (SIRT1) and PRDX5 activities while regulating inflammatory factors. Myricanol exhibits growth inhibition and induces apoptosis in human lung adenocarcinoma A549 cells. Myricanol promotes autophagy-mediated clearance of microtubule-associated protein tau to exert neuroprotective effects. Myricanol protects cardiovascular function by inhibiting PDGFRβ and NF-κB signaling pathways. Myricanol activates mitochondrial transcription factor A (TFAM) expression to exert anti-renal fibrosis effects. Myricanol improves insulin resistance through AMPK activation.

Pegloxenatide (Polyethylene glycol loxenatide) is a long-acting glucagon-like peptide-1 receptor (GLP-1RA) agonist. Pegloxenatide has various activities such as lowering blood glucose, lowering blood lipids, improving body weight, anti-inflammation, promoting wound healing, protecting the liver, and protecting the heart. Pegloxenatide can be used in the research of type 2 diabetes and its multiple complications.

Tanshindiol C is a S-adenosylmethionine-competitive EZH2 (Histone Methyltransferase) inhibitor with an IC₅₀ of 0.55 μM for inhibiting the methyltransferase activity. Tanshindiol C is also an activator of both Nrf2 and Sirtuin 1 (Sirt1) in macrophages. Tanshindiol C possesses anti-cancer activity, and can be used for atherosclerosis research.

Nicotinamide riboside tartrate, an orally active NAD⁺ precursor, increases NAD⁺ levels and activates SIRT1 and SIRT3. Nicotinamide riboside tartrate is a source of vitamin B3 (niacin) and enhances oxidative metabolism, protection against high fat diet-induced metabolic abnormalities. Nicotinamide riboside tartrate reduces cognitive deterioration in a transgenic mouse model of Alzheimer’s disease.

D-Galacto-D-mannan (Carob galactomannan) is an orally active Dectin-2 agonist. D-Galacto-D-mannan exerts antioxidant activity against hydroxyl radical generation. D-Galacto-D-mannan activates Dectin-2 to trigger downstream signaling pathways, promote the expression of immunoregulatory molecules, coordinate innate and adaptive immune responses, and inhibit excessive inflammatory responses by upregulating the expression of Sirtuin 1. When used as a vaccine adjuvant, D-Galacto-D-mannan induces cellular and humoral immune responses, promotes IFNγ secretion, increases antibody levels and virus neutralization titers, and elevates the levels of immunoglobulin G and A. D-Galacto-D-mannan can serve as an adjuvant for foot-and-mouth disease vaccines, enhance the vaccine-mediated ability of hosts to defend against viral infection in mice, and reduce local side effects at the inoculation site in pigs. D-Galacto-D-mannan can be used in the research of inflammatory and immune diseases, such as foot-and-mouth disease.

SIRT1 activator 3 is a potent activator of Sirt1 and suppresses TNF-α in a dose-dependent manner. SIRT1 activator 3 has the potential for anti-obesity or anti-diabetic researches.

AdipoR agonist 1 (Compound 112254) is an agonist for adiponectin receptor (AdipoR), which activates the transcriptional regulators like peroxisome proliferator-activated receptors (PPARs), peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α), sirtuin 1 (SIRT1), and adenylate-activated protein kinase (AMPK). AdipoR agonist 1 is utilized in preventive doping research.
