Descrizione

Descrizione generale

A cell-permeable quinone epoxide antibiotic that acts as a reversible, substrate competitive, and selective inhibitor of Bruton′s tyrosine kinase (BTK; IC₅₀ = 10 µM and 3 µM for the basal and activation levels), both in vitro and in vivo. Shown to bind to the BTK pleckstrin homology domain (BTK-PH) and block the interaction between BTK-PH and protein kinase C (PKC) (IC₅₀ ~100 µM in human mast cell lysates), thus affecting the catalytic activity of BTK, but not the activity of PKC. Selectively inhibits the autophosphorylation of PKC_βI (IC₅₀ ~8 µM) but not that of PKC_βII. Reported to effectively inhibit the production of TNF-α (IC₅₀ ~3 µM) and block the activation of JNK1 (IC₅₀ ~10 µM) in FcεRI-stimulated mast cells. Also reported to inhibit DNA synthesis in activated spleen cells (IC₅₀ ~1.5 µM). Does not significantly affect the activities of Lyn, Syk, PKA, CK-1, ERK1, ERK2 and p38 kinases.
