The synthesis and structure-activity relationship (SAR) trends of a new class of N-(azacycloalkyl)bisindolylmaleimides 1, acyclic derivatives of staurosporine, is described. The representative compound for this series (1e) exhibits an IC50 of 40-50 nM against the human PKCβ1 and PKCβ2 isozymes and selectively inhibits the PKCβ isozymes in comparison to other PKC isozymes (α, γ, δ, ε, λ, and η). The series is also kinase selective for PKC in comparison to other ATP-dependent kinases. A comparison of the PKC isozyme and kinase activity of the series is made to the kinase inhibitor staurosporine.
Synthesis of the tritiated isotopomers of enzastaurin and its N-des-pyridylmethyl metabolite for use in ADME studies

Enzastaurin (3-(1-methyl-1H-indol-3-yl)-4-[1-[1-(2-pyridinylmethyl)-4- piperidinyl]-1H-indol-3-yl]-1H-pyrrole-2,5-dione, 1), an agent with potential utility in the treatment of solid tumors, is currently in phase II clinical trials. Enzastaurin undergoes metabolism in vitro and in vivo to several products of oxidative metabolism, the major one of which is 3-(1-methyl-1H- indol-3-yl)-4-(1-piperidin-4-yl-1H-indol-3-yl)-1H-pyrrole-2,5-dione (2). In a model study, the attempted synthesis 1-[2H] by reaction of 1 with deuterium gas in the presence of Ir[(COD)(Cy3P)pyr]PF6 (Crabtree's catalyst) was unsuccessful. Alternatively, it was decided to prepare tritiated 2 as both a final product and the starting material for the tritiation of 1. We have reported herein a route that was developed for use in the preparation of tritium-labeled 2-[3H] and its successful conversion to 1-[3H]. Copyright

Enzastaurin (LY317615) is a potent and selective protein kinase C (PKC) inhibitor with an IC50 value of ~6 nM. [11C] Enzastaurin (3-(1-[11C]methyl-1H-indol-3-yl)-4-[1-[1-(2- pyridinylmethyl)-4-piperidinyl]-1H-indol-3-yl]-1H-pyrrole-2,5-dione), a new potential PET agent for imaging of PKC, was first designed and synthesized in 20-25% decay corrected radiochemical yield and 370-555 GBq/μmol specific activity at end of bombardment (EOB). The synthetic strategy was to prepare a carbon-11-labeled maleic anhydride intermediate followed by the conversion to maleimide.
