Laboratory of CNS active compounds, established in 2001, an experienced team of 15 chemists familiar with modern organic synthesis and medicinal chemistry approaches in drug discovery and development. Senior researchers have R&D experience in wide area of medchem projects, including medicines for CNS and peripheral regulation. Chemists have an experience in project oriented team work, networking with molecular modeling. Long term research in medicinal chemistry projects has been done in collaboration with Merz Pharmaceuticals, Germany. Research in organic chemistry – total synthesis of natural products and development of new synthetic methods – is organized by involving students from Riga Technical University and University of Latvia.
