The Haskell-Luevano Research Lab

Welcome to the Haskell-Luevano group website. Our research group is interested in the understanding of G protein-coupled receptors (GPCRs) and their involvement in feeding behavior, exercise, diabetes, and obesity.

We utilize multidisciplinary approaches including organic chemistry, chemical biology, biochemistry, molecular biology, pharmacology, physiology, animal studies, and neuroscience to study endocrine systems. A summary of the key elements of our research program along with relevant references can be found in the links below.

Design and synthesis of templates based on small molecules, peptides and peptidomimetics. The synthetic strategies involve solid-phase peptide synthesis using automated, semi-automated, manual and microwave synthesizers and multi-step organic synthesis. The lead identification and structure-activity studies generally use focused-library design or high throughput screening approaches.

The in vitro pharmacology of the compounds are established using functional bio-assays, binding, mutagenesis and pharmacokinetic studies. This provide the structural basis for ligand binding and activation, novel allosteric sites distinct from the orthosteric site, and ligand-directed differential signaling and regulation of receptors.

The Haskell-Luevano laboratory uses in vivo models to examine how melanocortin-specific drugs effect metabolic diseases.

After a drug is created, in vivo studies are performed in order to help verify the safety and effectiveness of the drug.
