Area of Science:
- Biochemistry and enzymology
- Drug discovery and medicinal chemistry
Background:
- Proteases are vital enzymes regulating numerous physiological processes, including inflammation, cell growth, and disease propagation.
- The six major protease classes (aspartic, serine, cysteine, threonine, glutamic, and metallo-) are implicated in various diseases.
- Protease inhibitors are key therapeutic targets, with a shift towards non-peptidic scaffolds.
Purpose of the Study:
- To review recent developments in non-peptidic cysteine and metallo-protease inhibitors.
- To focus on the design strategies employed for these novel inhibitors.
Main Methods:

01:30Enzyme Inhibition
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.
02:04Protein-protein Interfaces
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
02:34Enzymes
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
