Drug discovery remains a challenging and lengthy process, with the failure of drug candidates often occurring late in the pipeline due to properties such as poor pharmacokinetics, lack of efficacy or toxicity. My research focuses on the development of novel in silico methods in fragment-based lead discovery which considers these properties in the hit to lead optimisation. The aim is to produce an efficient workflow which systematically samples chemical space for the most promising set of molecules for a particular biological target and can be viewed as an “idea generator” to assist medicinal chemists in choosing what to make next after a hit is identified from an initial fragment screen.
