Duviragel™ (antiherpeticum)
An original Czech anti-shingles drug. This drug's development begun in 1976 when Prof. Holý first started working with Prof. Erik De Clerq (Catholic University of Leuwen). The Belgian virologist was researching new compounds and their effects on pathogenous viruses, and Prof. Holý sent him his samples. One of these compounds (DHPA), showed activity against certain viral pathogens with no associated toxicity. After ten more years of work, the Institute's and the Léčiva Měcholupy Company's teams developed Duviragel.
