    Product Description

    UCF 101 is an inhibitor of the proteolytic activity of Omi/HtrA2 (IC50 = 9.5 μM).1 It is highly specific for Omi/HtrA2, demonstrating less potent activity when tested against a panel of various other serine proteases (IC50s range from 200 to >500 μM).1 Additionally, UCF 101 is naturally fluorescent, thus enabling the visualization of its entry into cells.1 UCF 101 has been used to decrease cerebral infarct size in a rat model of cerebral ischemia, demonstrating neuroprotective effects by reducing apoptosis of cortical cells.2 It has also been reported to be protective of cardiomyocytes against ischemic injury through a mechanism that prevents Omi/HtrA2 proteolysis of Thanatos-associated protein 5, a cardiac-specific nuclear protein that controls cell cycle progression.3

    WARNING This product is not for human or veterinary use.
