The complexity of proteins has inspired chemists to seek artificial mimetics of protein structure and function. Historically, most such work has focused on analogues of small, isolated segments; however, there is growing interest in mimicry of larger, intact tertiary folds. This Perspective surveys the emerging body of work on these agents, termed ‘proteomimetics’, discusses their construction and outlines some of the remaining challenges.
The structures of biologically active natural products have long served as inspiration in drug discovery. This Perspective outlines design principles and connectivity patterns for the de novo combination of natural product-derived fragments. The resulting ‘pseudo-natural products’ retain biological relevance yet exhibit structures and bioactivities not found in the natural products and their derivatives.
