Development of chemical tools targeting the auxin pathway is useful for both plant biology and agriculture. Here we reveal that naproxen, a synthetic compound with anti-inflammatory activity in humans, acts as an auxin transport inhibitor targeting PIN-FORMED (PIN) transporters in plants. Physiological experiments indicate that exogenous naproxen treatment affects pleiotropic auxin-regulated developmental processes. Additional cellular and biochemical evidence indicates that naproxen suppresses auxin transport, specifically PIN-mediated auxin efflux. Moreover, biochemical and structural analyses confirm that naproxen binds directly to PIN1 protein via the same binding cavity as the indole-3-acetic acid substrate. Thus, by combining cellular, biochemical, and structural approaches, this study clearly establishes that naproxen is a PIN inhibitor and elucidates the underlying mechanisms. Further use of this compound may advance our understanding of the molecular mechanisms of PIN-mediated auxin transport and expand our toolkit in auxin biology and agriculture.","lang":"eng"}],"day":"13","language":[{"iso":"eng"}],"author":[{"first_name":"Jing","last_name":"Xia","full_name":"Xia, Jing"},{"full_name":"Kong, Mengjuan","last_name":"Kong","first_name":"Mengjuan"},{"last_name":"Yang","first_name":"Zhisen","full_name":"Yang, Zhisen"},{"full_name":"Sun, Lianghanxiao","last_name":"Sun","first_name":"Lianghanxiao"},{"full_name":"Peng, Yakun","first_name":"Yakun","last_name":"Peng"},{"last_name":"Mao","first_name":"Yanbo","full_name":"Mao, Yanbo"},{"full_name":"Wei, Hong","last_name":"Wei","first_name":"Hong"},{"full_name":"Ying, Wei","first_name":"Wei","last_name":"Ying"},{"last_name":"Gao","first_name":"Yongxiao","full_name":"Gao, Yongxiao"},{"orcid":"0000-0002-8302-7596","last_name":"Friml","first_name":"Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jiří"},{"last_name":"Weng","first_name":"Jianping","full_name":"Weng, Jianping"},{"first_name":"Xin","last_name":"Liu","full_name":"Liu, Xin"},{"last_name":"Sun","first_name":"Linfeng","full_name":"Sun, Linfeng"},{"full_name":"Tan, Shutang","last_name":"Tan","first_name":"Shutang"}],"ddc":["580"],"publication_identifier":{"eissn":["2590-3462"]},"article_processing_charge":"Yes","intvolume":"         4","citation":{"ieee":"J.
