Prof. Dr. A. Ganesan
Ganesan graduated with a BSc (Hons) in Chemistry from the National University of Singapore and a PhD from the University of California-Berkeley supervised by Clayton H. Heathcock. After postdoctoral research with Gregory Verdine at Harvard University, he was a Senior Research Chemist at the Centre for Natural Product Research, Singapore (1993-96) and Principal Investigator at the Institute of Molecular and Cell Biology, Singapore (1996-99). In 1999 he joined the University of Southampton as a Reader in the Combinatorial Chemistry Centre for Excellence. In 2011 he became the Chair of Chemical Biology at the University of East Anglia’s School of Pharmacy. His research is focused on chemical biology, medicinal chemistry and organic synthesis. Ganesan is co-founder of the drug discovery company Karus Therapeutics, Chair of the EU COST Action CM1406 Epigenetic Chemical Biology and a member of the IUPAC Subcommittee for Medicinal Chemistry and Drug Development.

Targeting Histone-Modifying Enzymes for Epigenetic Drug Discovery
Epigenetics is the study of how DNA and histone protein modification affect gene transcription in eukaryotes. The DNA and protein modifications are carried out by writer enzymes. For each modification, an eraser enzyme returns the molecule to its native state. In this project, we will target two key histone-modifying eraser enzymes, histone deacetylases (HDACs) and lysine-specific demethylase I (LSD1). HDAC inhibitors are a well validated epigenetic target for drug discovery with five approvals for cancer chemotherapy. However, there are issues with selectivity as the drugs inhibit several or all eleven of the human HDACs. Our approach is to design isoform-selective HDAC inhibitors and profile them biologically in order to understand the specificity that will be therapeutically valuable. In preliminary results, we have identified HDAC6 selective inhibitors. We will prepare two libraries of compounds based around two scaffolds and these will be evaluated in Freiburg. Concurrently, we will work on the second target, LSD1. We have a series of irreversible LSD1 inhibitors with submicromolar activity in acute myeloid leukaemia cell lines. We will prepare additional compounds in the series to optimize their pharmacodynamic and pharmacokinetic properties. In addition, we will identify scaffolds for reversible LSD1 inhibition through in silico screening. Promising candidates will be synthesized and tested in enzyme and cell-based assays for LSD1 inhibitory activity.
