Step 1

An infinity of molecules

Only a few molecules have what it takes to become a drug.

The number of possible molecular structures is greater than the number of seconds that have elapsed since the Big Bang. It is estimated at 10 to the power of 60.

Many of these molecular structures have never existed. Using their expert knowledge, as well as state-of-the-art scientific tools, Roche researchers produce thousands and thousands of new synthetic compounds in the laboratory, ‘inventing’ them by combining already known elements.

They then screen each one to find out which of them has what it takes to become a drug.
