New publication

Beactica scientists describe strategies for fragment-based drug discovery in two publications in Journal of Medicinal Chemistry.

Uppsala, Sweden, 4 February 2011

Beactica, the leading Swedish fragment-based drug discovery company,  announced the publication of two key papers based on in-house research in the field-leading Journal of Medicinal Chemistry*. The papers present methodological advances in SPR biosensor-based drug discovery targeting structurally dynamic proteins, a significant challenge for the pharmaceutical industry, that have been implemented in Beactica’s Sprint™ platform.

The first paper describes the identification of novel chemical scaffolds for inhibition of wild-type and drug-resistant HIV-1 reverse transcriptase by SPR-based fragment screening. The study demonstrates that an efficient experimental design can enable the identification of molecular fragments with desired characteristics and a defined mode of action – also for challenging targets. The second paper outlines concepts for an improved understanding of the druggability of target proteins during fragment-based lead generation. The Sprint™ methodology developed on the basis of the findings enables an improved evaluation and prioritization of screening hits.

The research is a result of an international collaboration between Beactica, IOTA Pharmaceuticals Ltd, Cambridge, UK, and scientists at Uppsala University, Sweden.
