Identifying the optimal drug treatment is like hitting a moving target. To stop disease, small-molecule drugs bind tightly to an important protein, blocking its effects in the body. Even approved drugs don`t usually work in all patients. And over time, infectious agents or cancer cells can mutate, rendering a once-effective drug useless.
