    AlphaFold is a breakthrough in protein structure prediction, but limitations in its application to computation- and structure-guided drug discovery remain. As with structure prediction, public-domain data and benchmarking initiatives will be essential to advance the field of computational drug design.

    Chemically reactive metabolites such as formaldehyde are often toxic and are proposed to react promiscuously with biomolecules. New work shows that some reactive sites on proteins are uniquely sensitive to formaldehyde, leading to functionally important regulation of protein and cell functions.

    Small molecules and drugs are not homogenously distributed across cells, and are instead enriched in distinct subcellular compartments and membraneless biomolecular condensates. A new study lays out the path to identifying chemical features or ‘rationales’ that confer condensate-selective partitioning of small molecules.
