Abstract: Equipotent indolocarbazole-derived analogs of staurosporine identified herein are prepared through C—H borylation chemistry. Functionality resides at C2 and C10 of the indolocarbazole aromatic region. Introducing functionality in this previously inaccessible region does not abrogate kinase activity and is shown to change the selectivity profile.
