Pricing Availability Delivery Time Qty
Cat.No. 4569 - PS 1145 dihydrochloride | CAS No. 1049743-58-9
Description: Selective IKK inhibitor; orally active
Chemical Name: N-(6-Chloro-9H-pyrido[3,4-b]indol-8-yl)-3-pyridinecarboxamide dihydrochloride
Purity: ≥98% (HPLC)

Biological Activity

Selective IκB kinase (IKK) inhibitor (IC50 = 100 nM). Has no effect on PKA, PKC and CKII activity. Inhibits IκB-α phosphorylation and NFκB activation in HeLa cells. Inhibits NFκB-mediated proinflammatory gene expression in human airway epithelial cells. Enhances TNF-α-induced apoptosis in a multiple myeloma cell line. Attenuates LPS-induced TNF-α production in vivo. Orally active.
