产品描述：
CA-074, a specific cathepsin B inhibitor, also abolished the neurotoxic effects caused by Abeta42-activated BV2 cell [1]. Co-treatment of cultures with the cathepsin B inhibitors CA-074 or Z-FA-FMK suppressed the cytostatic effects of TPA and activation of pro-uPA [2]. Administration of CA-074 suppresses the response to exogenous antigens, such as hepatitis B virus antigen, ovalbumin and Leishmania major antigen, and induces switching of the helper T cell responses from Th-2 to Th-1 of CD4+ T cell, thereby down regulating the production of IgE and IgG1 [3]. Pharmacological inhibition of cat B in catB(+/+) mice with L-3-trans-(propylcarbamoyl)oxirane-2-carbonyl-Lisoleucyl-L-proline (CA-074 Me) also reduced TNF-alpha-induced liver damage. [4] Administration of cathepsin B inhibitors, E-64, CA-074 and vitamin B6, caused the strong suppression of the Th-2 type immune responses .

Inhibitor of cathepsin B (Ki = 2-5 nM). Displays selectivity over cathepsins H and L (Ki = 40-200 μM). Shown to reduce bone metastasis in a 4T1.2 breast cancer model.
