ERK2 Activator

Phenylhydroquinone (PHQ) is an orally active thymic atrophy inducer which can up-regulate apoptosis through activation of p53. PHQ can be used for research of thymic atrophy.

Zoniporide hydrochloride hydrate (Standard) (CP-597396 hydrochloride hydrate (Standard)) is the analytical standard of Zoniporide hydrochloride hydrate (HY-105064D). This product is intended for research and analytical applications. Zoniporide hydrochloride hydrate (CP-597396 hydrochloride hydrate) is a selective Na⁺/H⁺ exchanger subtype 1 (NHE1) inhibitor with cardioprotective activity, with IC₅₀ values of 67 nM and 73 nM against rat NHE1. Zoniporide hydrochloride hydrate reduces intracellular Na⁺ and Ca²⁺ overload, preserves mitochondrial integrity, activates pro-survival ERK1/2 and STAT3 signaling pathways, reduces necrosis and apoptosis, and decreases neutrophil aggregation. Zoniporide hydrochloride hydrate is applicable to research related to myocardial ischemia-reperfusion injury and heart graft ischemia-reperfusion injury.

Benfluron hydrochloride is an Apoptosis inducer and inhibitor of the HIV-1 Rev-RRE complex, with an IC₅₀ of 5.0 μM against the HIV-1 Rev-RRE complex. Benfluron hydrochloride induces p53 activation, and triggers phosphorylation of Chk1 at serine 345, Chk2 at threonine 68, as well as ERK1/2 at threonine 202 and tyrosine 204. Benfluron hydrochloride activates Caspase 8, Caspase 9 and Caspase 3/7, inhibits HIV-1 viral transcription, and acts as a substrate for 11β-HSD 1 and cytosolic carbonyl reductase. Benfluron hydrochloride can be used in research related to leukemia and HIV-1 infection.

Tubulozole hydrochloride (R 46846 hydrochloride) is an orally active inhibitor of tubulin polymerization with an ID₅₀ of 0.34 μM. Tubulozole hydrochloride induces activation of the Chk1 kinase and phosphorylation of ERK1/2, which is required for microtubule formation. Tubulozole hydrochloride arrests Mitosis at the metaphase stage. Tubulozole hydrochloride causes cells to accumulate in the radiosensitive mitotic phase of the cell cycle. Tubulozole hydrochloride exerts anticancer activity against colon cancer. Tubulozole hydrochloride produces a radiosensitizing effect in mouse tumor models and enhances the tumor growth delay effect when combined with γ-ray irradiation. Tubulozole hydrochloride is used in studies related to colon cancer, fascioliasis, MO4 fibrosarcoma, and Lewis lung carcinoma.

Famotidine-¹³C (MK-208-¹³C) is the ¹³C-labeled Famotidine (HY-B0377). Famotidine (MK-208) is an orally active and highly selective histamine H2 receptor antagonist. It inhibits gastric acid secretion by blocking the Gs signaling pathway, and regulates intracellular cAMP and ERK pathways. Famotidine inhibits TLR3-mediated inflammatory pathways, and reduces the expression of various inflammatory mediators and interferon-related genes. Famotidine scavenges DPPH and nitric oxide free radicals, alleviates oxidative stress damage in gastric tissue, inhibits proMMP-9, improves vascular endothelial permeability, and restores the normal physiological functions of neutrophils and eosinophils. Famotidine crosses intestinal epithelial cells via facilitated diffusion and passive diffusion, blocks paracellular cation transport, and increases intestinal transepithelial electrical resistance. Famotidine reduces serum levels of transaminases and alkaline phosphatase, exerts analgesic effects and gastric protective effects simultaneously. Famotidine can be used in studies related to COVID-19, liver injury and acute gastric ulcer.

MptpB-IN-3 is a selective inhibitor of Mycobacterium tuberculosis protein tyrosine phosphatase B (MptpB) with an IC₅₀ of 0.19 μM. MptpB-IN-3 blocks MptpB-mediated inhibition of the macrophage MAPK pathway and restores the phosphorylation levels of Erk1/2 and p38. MptpB-IN-3 exhibits direct anti-tuberculosis activity against Mycobacterium tuberculosis and reduces the Mycobacterium tuberculosis load in mouse macrophages. MptpB-IN-3 can be used for tuberculosis research.
