Fragment-based discovery enables direct targeting of the melanoma oncogene MITF.

ABSTRACT: Despite the improvement of therapeutic options, melanoma patients with advanced metastatic disease are still in high need of durable treatments. Analysis of clinical data from patients receiving targeted and/or immunotherapy, along with genetic and functional studies in preclinical melanoma models, demonstrates the key role of the microphthalmia-associated transcription factor (MITF) throughout disease progression, and provides a solid rationale for its therapeutic inhibition. However, direct targeting of MITF or other basic helix-loop-helix leucine zipper (bHLH-LZ) transcription factors is unprecedented. Here, we report on the discovery of ligands for the DNA binding domain of MITF, using fragment-based screening (FBS) by nuclear magnetic resonance (NMR). Initial fragments, binding the ki
