Chemical Biology Consortium Sweden (CBCS) is a national network for chemical biology with focus on small molecule screening and compound optimization and profiling. CBCS aims to produce high quality pharmacological tools in collaborative academic projects on a national level and does so by providing expertise in assay development, screening, medicinal and computational chemistry and pharmaceutical profiling. Here we present an overview of the national infrastructure, which is composed of three nodes located at Umeå University, Uppsala University and Karolinska Institutet. In addition we present some early screening results from collaborative projects. Open the poster in PDF
