Capturing a coactivator, naturally: The natural products sekikaic acid and lobaric acid, isolated after a high-throughput screen of a structurally diverse extract collection, effectively target the dynamic binding interfaces of the GACKIX domain of the coactivator CBP/p300 (see structure). These molecules are the most effective inhibitors of the GACKIX domain yet described and are uniquely selective for this domain.
