113963-68-1

Ro 31-6045 (113963-68-1) is a bis indolylmaleimide derivative that is a potent inhibitor of the mitogen-stimulated protein kinase p70 (S6K) acting independently of its upstream activator mTOR.1?Does not inhibit PKC (at concentrations <100?mM) and therefore may be used as a negative control for bisindolylmaleimide PKC inhibitors2?such as GF 109203X3?and other structurally related inhibitors4.

Bisindolylmaleimide V is a cell-permeable negative control for protein kinase C inhibition studies with an IC50 value over 100 μM[1]. Bisindolylmaleimide V blocks the activation of mitogen-stimulated protein kinase p70s6k/p85s6k (S6K) in vivo with an IC50 of 8 μM[2].

ChEBI: Ro 31-6045 is a member of indoles.
