Research Mini-Symposium at Drexel University

The Malaria Problem

• Over 300 million people a year infected

• Over 1 million deaths per year

• Increasing resistance to existing drugs means there is a pressing need for new anti-malarial agents

The Ugi Reaction

Virtual library of 500K Ugi products

Some Ugi products predicted to bind to malarial enzymes

Enoyl reductase

Falcipain-2

• Breaks down hemoglobin
