Selective TBK1/IKKi dual inhibitors with anticancer potency.

ABSTRACT: Increasing evidence suggests that the noncanonical IKKs play critical roles in tumor genesis and development, leading to the notion that noncanonical IKKs may be good targets for cancer therapy. Here, we demonstrate that although TBK1 is not overexpressed or constitutively activated in some tumor cells, targeting IKKi induces the activation of TBK1. Therefore, simultaneously targeting both kinases is necessary to efficiently suppress tumor cell proliferation. We show that three TBK1/IKKi dual inhibitors, which are based on a structurally rigid 2-amino-4-(3'-cyano-4'-pyrrolidine)phenyl-pyrimidine scaffold, potently inhibit cell viability in human breast, prostate and oral cancer cell lines. Treatment with these TBK1/IKKi dual inhibitors significantly impairs tumor development in xenograft a
