Application

TPCA-1 has been used to study its cytotoxic effects in RPMI8226 and LP1 cell lines. It has also been used as a culture media supplement for nuclear protein fractions extracted from human airway smooth muscle cells.

Biochem/physiol Actions

TPCA-1 is a potent and selective inhibitor of human IκB kinase-2 (IKK-2) with IC50 = 17.9 nM for IKK-2 compared to 400nm for IKK-1. It has been used to study inhibition of IKK-2 to prevent inflammatory mediator release in animal models of arthritis and airway inflammation.

Nuclear factor kappaB (NF-kappaB) is a transcription factor believed to be central in the expression of numerous inflammatory genes and the pathogenesis of many respiratory diseases. We have previously demonstrated increased NF-kappaB pathway activation in a steroid-sensitive animal model of

Clinical and experimental evidence indicates that macrophages could promote solid-tumor progression and metastasis. However, the mechanisms underlying this process remain unclear. Here we show that yes-associated protein 1 (YAP1), a transcriptional regulator that controls tissue growth and regeneration, has an

Induction of interferon beta (IFN-β), IFN-stimulated genes (ISGs), and inflammatory responses is critical for control of viral infection. We recently identified an essential linkage of stimulation of the inflammatory cytokine interleukin-1β (IL-1β) and induction of ISGs that function as host

Demonstration that IkappaB kinase 2 (IKK-2) plays a pivotal role in the nuclear factor-kappaB-regulated production of proinflammatory molecules by stimuli such as tumor necrosis factor (TNF)-alpha and interleukin (IL)-1 suggests that inhibition of IKK-2 may be beneficial in the treatment
