ask1 in 2

ASK1-IN-2 is a potent, orally active inhibitor of apoptosis signal-regulating kinase 1 (ASK1), with an IC50 of 32.8 nM. It has potential therapeutic applications for ulcerative colitis[1].

ASK1-IN-7 (Compound 4c) is an ASK1 inhibitor and a derivative of the ASK1 inhibitor scaffold 5-(5-Phenyl-furan-2-ylmethylene)-2-thioxo-thiazolidin-4-one. This compound is potentially applicable in research involving ASK1 signaling pathways, including studies on cellular stress response, inflammatory response, neurodegenerative diseases, and cardiovascular diseases.

TrxR2-IN-1 is an inhibitor of thioredoxin reductase 2 (TrxR2) with an IC50 value of 0.83 μM. It accumulates in mitochondria, disrupting their function and membrane potential, elevating reactive oxygen species (ROS) levels, and activating ASK1-mediated caspase-dependent apoptosis. TrxR2-IN-1 induces G2/M phase cell cycle arrest and inhibits cancer cell migration, making it applicable for hepatocellular carcinoma research.

(E)-2-(2-Chlorostyryl)-3,5,6-trimethylpyrazine (CSTMP) is a stilbene derivative with antioxidant and anticancer activities. It stimulates proliferation of hydrogen peroxide-damaged ECV-304 cells (EC50 = 24.9 nM). CSTMP reduces hydrogen peroxide-induced release of lactate dehydrogenase (LDH) in and increases viability of human umbilical vein endothelial cells (HUVECs) in a concentration-dependent manner via inhibition of apoptosis. It reverses hydrogen peroxide-induced release of malondialdehyde (MDA) and decreases in superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities as well as increases constitutive nitric oxide synthase (cNOS) activity and nitric oxide (NO) production in HUVECs. CSTMP also induces cell death of A549 non-small cell lung cancer (NSCLC) cells in an IRE1α-dependent manner through induction of IRE1α-TRAF2-ASK1 complex-mediated endoplasmic reticulum (ER) stress and mitochondrial apoptosis.
