Drug development is a painstaking process iteratively progressing through the stages of hit discovery, hit-to-lead and lead optimization followed by identification of a clinical candidate. To mitigate problems arising during the drug development process, bioisoteric replacement is often used. This project is intended to explore synthetic routes towards sulfur-based bioisosteres of γ-lactams, the scaffold ubiquitously present in bioactive molecules.
The project aims to develop methods for stereoselective synthesis of potential drug molecules. These synthetic approaches will be used to develop next generation analogues for neuroprotective drugs.
