The Geometry of Activity Cliffs: Representation Dependence and Multi-Scale Characterization of Activity Landscapes
A new research paper published on arXiv explores the concept of "activity cliffs" in quantitative biology, which are pairs of similar molecules with vastly different potency. The study argues that these cliffs are often a result of the chosen molecular representation rather than an intrinsic property of the molecules themselves. Researchers developed a pipeline to analyze various molecular representations and found that no single representation excels across all criteria, highlighting that different representations capture different aspects of molecular recognition.
