PS-1145 二盐酸盐，5MG，P6624-5MG，Sigma

Application

PS-1145 dihydrochloride has been used as an IκB kinase (IKK) inhibitor:

• in the culture medium to treat human epidermal keratinocytes (HEKs) and squamous carcinoma cells (SCCs) to study the role of IKK in Corynebacterium tuberculostearicum (C. t.)-elicited transcription of inflammatory mediators
• to investigate the involvement of transcription factor p65 (RelA)/nuclear factor kappa-B (NF-κB) in the cluster of differentiation 28 (CD28)-mediated interleukin-17A (IL-17A) gene expression
• to examine the involvement of NF-κB signaling in the cytotoxic effect of niclosamide on colorectal cancer (CRC) cells

Biochem/physiol Actions

PS-1145 is an IKB kinase (IKK) inhibitor.
PS-1145, a β-carboline derivative, blocks the phosphorylation and degradation of the inhibitor of nuclear factor kappa-β (NF-κB;). It also inhibits the subsequent activation of nuclear factor kappa-β (NF-κB) and thereby prevents the release of tumor necrosis factor-α (TNF-α) in lipopolysaccharide treated mice. PS-1145 hinders pro-inflammatory cytokine production and cell proliferation. It plays a potential therapeutic role in carcinogenesis in multiple myeloma. PS-1145 exhibits anti-tumor activity on nasopharyngeal carcinoma (NPC) cell lines.
