Research Summary: Peptide and Protease Targets in Brain Disorders for Drug Discovery
The focus of research in the Hook Laboratory is to identify peptide and protease neurochemical mechanisms as new drug target strategies for brain disorders including neurological, neurodegenerative, and mental health diseases. The research addresses discovery of new drug strategies for Alzheimer’s and Huntington’s neurodegenerative diseases, traumatic brain injury (TBI), chronic pain, and mental health conditions of schizophrenia and bipolar disease. The neurochemical drug target strategies involve neurotransmitter profiling analyses by peptidomics and metabolomics mass spectrometry combined with proteomics, chemical biology of protease targets, genetics, via human brain focused investigations. Drug discovery combines evaluation of marine natural products with analyses of clinical drug molecules. This research addresses the unmet need for new therapeutic drugs to treat brain disorders.

Key Contributions to Pharmaceutical Sciences
- Protease Pathways for Peptide Neurotransmitter Production, Chemical Biology, Mass Spectrometry
- Alzheimer’s and Neurodegenerative Disease Protease Drug Targets. Alzheimer’s disease (AD), Huntington’s disease, and other neurodegenerative diseases produce neurotoxic peptides by proteases. These proteases represent new drug targets for discovery of novel therapeutic agents.
- Traumatic Brain Injury (TBI) protease drug target prevents cell death and brain dysfunction.
- Chronic pain is improved by targeting spinal dynorphin neurotransmitter.
- Neurotransmitter Profiling by Mass Spectrometry in Brain Disorders: Drug Targets and Biomarkers.
- Modeling of Schizophrenia and Brain Neurons by Human Induced Pluripotent Stem Cell Neurons.
