The Marshall Lab performs a synergistic application of organic synthesis (solution- and solid-phase chemistry), enzymatic assays (electrophoretic mobility shift assays (EMSA) and surface plasmon resonance (SPR)), and computational chemistry techniques (homology modeling, molecular docking, molecular dynamics simulations, QSAR and 3D QSAR models) to rationally develop novel isoform-selective Lysine Deacetylases Inhibitors (KDACIs) as new therapeutics for the treatment of cancer, HIV-1, schistosomiasis and malaria.

Title: Isoform-selective lysine deacetylase inhibitors
Patent #: US20180230181
Kind: A1
Inventor(s): Garland R. Marshall, George B. Kyei, Michael D. Onken, Lee Ratner, Nandarapu Damodara Reddy
Isoform-selective lysine deacetylase inhibitors are described. Inhibitors of the lysine deacetylase enzyme are useful as antitumor drugs and for treating addiction, asthma, cardio-vascular disease, immunosuppression, neurodegenerative diseases, sepsis, sickle-cell disease, uveal melanoma and termination of viral latency, particularly HIV-1 latency.
