PKCθ/δ Inhibitor

A cell-permeable pyridinecarbonitrile compound that acts as a potent, ATP-competitive (K_i = 79 nM, using PKCθ KD in coupled PK/LDH assays), and isozyme-selective PKCθ inhibitor (IC₅₀ = 70 nM) with much reduced potency against other novel PKCs (IC₅₀ = 0.35, 2.33, and 16.35 µM against δ, ε, and η isoforms, respectively) and little or no activity against the conventional PKCβ and atypical PKCζ (IC₅₀ >50 µM) as well as a panel of 18 other commonly studied cellular kinases (IC₅₀ >10 µM). Shown to preferentially inhibit IL-2 production from anti-CD3- and anti-CD28-activated T cells derived from wild-type over PKCθ-knockout mice (IC₅₀ = 58 and 231 nM, respectively).
