Research paper questions molecular representation's role in activity cliffs

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.

    The Geometry of Activity Cliffs: Representation Dependence and Multi-Scale Characterization of Activity Landscapes

    arXiv:2605.30831v1 Announce Type: cross Abstract: Activity cliffs, structurally similar compounds with large potency differences, are widely treated as intrinsic features of chemical datasets. We argue that apart from target biology, much of our cliff understanding is a consequen…
