Structurally Diverse Histone Deacetylase Photoreactive Probes: Design, Synthesis, and Photolabeling Studies in Live Cells and Tissue.

Published in Chem Med Chem, 2019

Significance: In this study we describe a robust synthetic strategy to access chemically diverse photoreactive probes (PRPs), which we used to prepare PRPs based on seven HDAC inhibitor scaffolds. The selectivity of these PRP chemotypes for HDAC isoforms was characterized by biochemical assays and photolabeling experiments in cell lines and mouse liver tissues, relevant for the design of isoform selective HDAC inhibitors.

Divergent JNK Phosphorylation of HDAC3 in Breast Cancer Cells Determines HDAC Inhibitor Binding and Selectivity

Published in Cell Chemical Biology, 2017

Significance: This work demonstrates that histone deacetylase (HDAC) inhibitor selectivity and efficacy is regulated by HDAC phosphorylation and characterizes a novel pathway catalyzing HDAC3 phosphorylation mediated by c-Jun N-terminal kinase, differentially active across breast cancer subtypes. Thus, the selectivity and efficacy of HDAC inhibitors is cell type-dependent, which is not recapitulated in vitro analysis, and provides a strategy to improve HDAC inhibitor efficacy for breast cancer treatment.
