Biological Activity

[Description]:

Bisindolylmaleimide XI hydrochloride (Ro 32-0432) is a potent, selective and orally active PKC inhibitor with IC50s of 9 nM, 28 nM, 31 nM, 37 nM, and 108 nM for PKCα, PKCβI, PKCβII, PKCγ, and PKCε, respectively[1][2].

[Target]

PKC-α:9 nM (IC50)

PKC-βI:28 nM (IC50)

PKC-βII:31 nM (IC50)

PKC-γ:37 nM (IC50)

PKC-ε:108 nM (IC50)

[In Vitro]

Bisindolylmaleimide XI hydrochloride (Ro 32-0432) inhibits IL-2 secretion, IL-2 receptor expression in, and proliferation of, peripheral human T-cells stimulated with phorbol ester together with phytohemagglutin or anti-CD3, but does not inhibit IL-2 induced proliferation in cells already stimulated to express IL-2 receptors. Proliferation of the influenza peptide antigen HA 307-319-specific human T-cell clone (HA27) after exposure to antigen-pulsed autologous presenting cells is also inhibited by Bisindolylmaleimide XI hydrochloride[2]. PKC inhibition with Bisindolylmaleimide XI hydrochloride (Ro 32-0432; 1 μM) decreases the proportion of apoptotic cells (-21%) in retinal progenitor cells (RPCs)[3].

[In Vivo]

Oral administration of Bisindolylmaleimide XI hydrochloride inhibits subsequent phorbol ester-induced edema in ratss. Induction of more physiologically T-cell driven responses such as host vs. graft responses and the secondary paw swelling in adjuvant-induced arthritis are also inhibited by Bisindolylmaleimide XI hydrochloride[2].
