引用ジャーナル : Structure / 年 : 2020タイトル : The Binding of Palonosetron and Other Antiemetic Drugs to the Serotonin 5-HT3 Receptor.著者 : Eleftherios Zarkadas / Hong Zhang / Wensheng Cai / Gregory Effantin / Jonathan Perot / Jacques Neyton / Christophe Chipot / Guy Schoehn / Francois Dehez / Hugues Nury / 要旨 : Inaccurately perceived as niche drugs, antiemetics are key elements of cancer treatment alleviating the most dreaded side effect of chemotherapy. Serotonin 5-HT3 receptor antagonists are the most ... Inaccurately perceived as niche drugs, antiemetics are key elements of cancer treatment alleviating the most dreaded side effect of chemotherapy. Serotonin 5-HT3 receptor antagonists are the most commonly prescribed class of drugs to control chemotherapy-induced nausea and vomiting. These antagonists have been clinically successful drugs since the 1980s, yet our understanding of how they operate at the molecular level has been hampered by the difficulty of obtaining structures of drug-receptor complexes. Here, we report the cryoelectron microscopy structure of the palonosetron-bound 5-HT3 receptor. We investigate the binding of palonosetron, granisetron, dolasetron, ondansetron, and cilansetron using molecular dynamics, covering the whole set of antagonists used in clinical practice. The structural and computational results yield detailed atomic insight into the binding modes of the drugs. In light of our data, we establish a comprehensive framework underlying the inhibition mechanism by the -setron drug family. 履歴 登録 2020年2月14日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2020年3月4日 Provider : repository / タイプ : Initial release改定 2.0 2020年7月29日 Group : Advisory / Atomic model ...
