Biochem/physiol Actions

KINK-1 (Kinase Inhibitor of NF-ΚB-1; Bay 65-1942; CmpdA; Compound A) is an ATP-competitive, IKKβ-selective IΚB kinase (IKK) inhibitor (Ki against ATP = 2 nM/IKKβ and 135 nM/IKKα) that potently inhibits IKKβ-catalyzed GST-IΚBα(1–54) phosphorylation (IC50 = 4 nM, 200 nM ATP) without affecting (IC50 >10μM) IKK3 or 27 other kinases, lipases, phosphatases, caspases, and MMPs. KINK-1 effectively inhibits NF-ΚB activation and cytokines production in various human and murine cultures (IC50 from 18 to 502 nM) and is efficacious against LPS-induced plasma TNF-α production in mice and rats in vivo (EC50 = 9.1 and 6.6 mg/kg p.o., repectively) with good pharmacokinetic profile and oral availability. KINK-1 is also shown to effectively inhibit OVA-induced lung inflammation in a rat model of asthma (ED50 <0.3 mg/kg p.o.) without adverse effects to the animals.

Increasing the efficacy of chemotherapeutics by reducing chemoresistance may be a useful strategy in cancer therapy. Constitutive activation of nuclear factor-kappa B (NF-kappaB) is a hallmark of various cancers, including melanoma, which is almost universally resistant to chemotherapy. NF-kappaB is

Lung cancer is the leading cause of cancer death. Beyond first line treatment, few therapeutic options are available, particularly for squamous cell carcinoma (SCC). Here, we have explored the phospholipidomes of 30 human SCCs and found that they almost invariably

Cytosolic DNA can elicit beneficial as well as undesirable immune responses. For example, viral or microbial DNA triggers cell-intrinsic immune responses to defend against infections, whereas aberrant cytosolic accumulation of self-DNA results in pathological conditions, such as autoimmunity.
