CNB-001
CNB-001 is a potent and orally active 5-lipoxygenase (5-LOX) inhibitor. CNB-001 can decreases 5-LOX expression and increase proteasome activity. CNB-001 can inhibit accumulation of soluble Amyloid-β and ubiquitinated aggregated proteins. CNB-001 can inhibit apoptosis, ROS production and stabilize mitochondrial membrane potential. CNB-001 can reduce insulin resistance and increase glucose uptake. CNB-001 also exhibits anti-ischemic, anti-inflammatory effects. CNB-001 can be used for the researches of inflammation, neurological and metabolic disease, such as Alzheimer's disease, stroke and diabetes.

NB-001 (0.5-15 μM, 24 h) exhibits a half-toxic concentration (TC50) of 15.3 μM in quiescent C2C12 myotubes[3].
CNB-001 (1 μM, 12 h) reverses Palmitic acid (HY-N0830)-induced insulin resistance and restores insulin-stimulated glucose uptake in C2C12 myotubes[3].
CNB-001 protects SK-N-SH human neuroblastoma cells against Rotenone (HY-B1756)-induced neurotoxicity by inhibiting intracellular ROS generation, apoptosis and stabilizing mitochondrial membrane potential[4].
