Aberrantly activated signal transducer and activator of transcription 3 (Stat3) protein plays a master regulatory role in the progression and survival of human cancers through the upregulation of target protooncogenes. Numerous human cancers, including breast, ovarian, prostate, leukemia, lymphoma, multiple myeloma, and brain cancers have been shown to harbor constitutively active Stat3 protein resulting in the expression of protooncogenes. The transcriptionally active Stat3-Stat3 protein homodimer has been extensively targeted as a means to suppress the aberrant Stat3 function in human cancer. This review will outline the recent progress made toward identifying drug-like compounds capable of effectively inhibiting aberrant Stat3 signaling through the disruption of Stat3 protein-protein interactions.
