Biological Activity for Bisindolylmaleimide II
Bisindolylmaleimide II is a potent, ATP-competitive protein kinase C (PKC) inhibitor (IC50 = 0.01 μM). Displays selectivity for PKC over protein kinase A (PKA) and phosphorylase kinase (PK) (IC50 values are 0.75 and 2μM for PK and PKA respectively). Also displays potent, noncompetitive antagonism at nicotinic cholinergic receptors (IC50 ~ 0.03 μM for inhibition of catecholamine secretion in nicotine-stimulated PC-12 cells).

Bisindolylmaleimide II (BII) was used to block PKC in hippocampal granule cells. Such a block enhances activity of GABA receptors and, as a sequence, increases effect of competitive antagonists of GABA on root mean square noise (RMS) amplitude of holding current in electrophysiological recording. Figure: changes of RMS after application of SR 95531 and SR 95531 + Picrotoxin. BII makes significant an effect of SR 95531 applied alone.
