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.

Constitutive activation of the NF-kappaB pathway is required for survival of the activated B cell-like (ABC) subgroup of diffuse large B-cell lymphoma (DLBCL). Here we show that a small molecule IkappaB kinase (IKK) inhibitor, PS-1145, and related compounds are toxic

Wnt/β-catenin pathway activation caused by adenomatous polyposis coli (APC) mutations occurs in approximately 80% of sporadic colorectal cancers (CRC). The antihelminth compound niclosamide downregulates components of the Wnt pathway, specifically Dishevelled-2 (Dvl2) expression, resulting in diminished downstream β-catenin signaling. In

Staphylococcus aureus is a gram-positive bacterium that may cause intestinal inflammation by secreting enterotoxins, which commonly cause food-poisoning and gastrointestinal injuries. Staphylococcal enterotoxin B (SEB) acts as a superantigen (SAg) by binding in a bivalent manner the T-cell receptor (TCR)
