Extensive analyses of successful and failed compounds in drug discovery and development have improved our understanding of the role of physicochemical properties in attrition. They have also clarified the difficulties in finding the 'sweet spot' in medicinal chemistry programmes. Hann and Keserü discuss scientific, strategic and cultural considerations for medicinal chemistry practices, with the aim of promoting more effective use of what is already known, and a wider appreciation of the risks of pursuing suboptimal compounds.
