Small Molecule Therapeutics

The Power of Small Molecules and its Potential Targets.

Many small molecules can work as therapeutic agents. Novel synthetic compounds and endogenous molecules, such as metabolites, can influence biology by modifying its availability within a cell. New and effective molecular therapeutics capitalize on these findings and are being further developed at UMassMed. In addition, there is research into identifying the critical molecular targets that may enable further discoveries of therapeutic targets.
