Overview of Fatty Acid Metabolism01:28

Overview of Fatty Acid Metabolism

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Area of Science:

  • Medicinal Chemistry
  • Chemical Biology
  • Pharmacology

Background:

  • Fatty acids are crucial signaling molecules but often lack therapeutic potency and selectivity due to conformational flexibility.
  • Understanding the specific functional conformation of fatty acids is key to developing effective, targeted therapeutics.
  • Current limitations hinder the design of natural-product-inspired ligands with improved properties.

Purpose of the Study:

  • To establish a molecular strategy for investigating the biological relevance of different fatty acid conformers.
  • To develop potent and selective fatty acid mimetics inspired by natural products.
  • To identify specific ligand-receptor interactions for therapeutic applications.

Main Methods:

  • Developed "conformational profiling" using a library of chiral, conformationally constrained fatty acids.
  • Synthesized a 24-membered collection of oleic acid mimetics with varied stereochemistry.
  • Employed advanced stereoselective synthesis techniques to create diverse fatty acid analogs.

Main Results:

  • Identified fatty acid mimetics with significantly enhanced potency and selectivity.
  • Discovered specific mimetics biased for G-protein coupled receptors (GPCRs) like GPR40 and GPR120.
  • Found other mimetics that act as potent and selective modulators of the nuclear receptor TLX.

Conclusions:

  • Established a foundational strategy for designing natural-product-inspired fatty acid mimetics.
  • Demonstrated the potential of conformationally constrained analogs as valuable tools in chemical biology.
  • These findings pave the way for developing novel therapeutic leads based on fatty acid structures.
