November 15, 2001: HIV drug developed after Czech discovery introduced in Czechia
Professor Antonín Holý often remarked that chance plays a major role in science. One such fortunate combination of circumstances eventually led to the development of Viread, a drug introduced to the Czech public 25 years ago. Based on a discovery by Czech scientists, the drug became one of the cornerstones of modern HIV treatment and remains one of the most significant international achievements of Czech science.
Few scientific discoveries make the journey from the laboratory bench to millions of patients across every continent. The story of Viread is one such example.
The drug, which was introduced to the Czech public on 15 November 2001, became an important part of HIV treatment. Its active ingredient is tenofovir, whose development was based on the work of Czech chemist Antonín Holý and his colleagues at the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences.
Today, tenofovir is included on the World Health Organization's Model List of Essential Medicines, placing it among the drugs considered indispensable for healthcare worldwide.
A meeting that produced unexpected results
The beginnings of this successful scientific journey date back to the 1970s. In 1976, Antonín Holý met Belgian virologist Erik De Clercq at a scientific symposium in Germany. The collaboration that began there lasted several decades and resulted in a number of important antiviral drugs.
Holý himself later recalled in an interview with RPI that their meeting had been a matter of chance.
“We happened to meet at a particular point in space and time. He came up with an idea, and I happened to have certain compounds that were interesting.”
The combination of Czech chemistry and Belgian virology proved exceptionally productive. The very first samples of compounds sent to Belgium showed promising results, and the collaboration continued.
An important step in the fight against HIV
When Viread was introduced, HIV infection was one of the world's greatest public health challenges. Although doctors had several treatment options available, the disease remained incurable and claimed hundreds of thousands of lives every year.
Viread did not provide a definitive cure. However, it offered a new way to suppress the virus effectively and slow the progression of the disease. Thanks to drugs like this, HIV was gradually transformed from what had been an almost certain death sentence into a chronic condition that can be managed over the long term with appropriate treatment.
Another advantage of tenofovir was that the virus developed resistance to it more slowly than to many older drugs. The medication also subsequently proved effective in treating chronic hepatitis B.
Czech Science with a Global Impact
During his career, Antonín Holý published hundreds of scientific papers and contributed to dozens of patents. His discoveries led to the development of several important antiviral drugs used around the world.
