confusion concerning the stereochemical configuration at the exocyclic double bond persists in the literature, thus restricting further drug development of this compound and derivatives. By using NMR and quantum mechanical calculations, this work establishes the stereoconfiguration as the (Z) form and that the effect of a single hydrogen bond is crucial in keeping these types of molecules in a single configuration
有效和选择性肌球蛋白抑制剂在开发治疗涉及肌球蛋白功能障碍或过度活动的疾病方面具有巨大的科学兴趣。一种新型杀菌剂 2-氰基-3-氨基-3-苯基丙烯酸乙酯(商品化为“phenamacril”)最近被鉴定为禾谷镰刀菌中肌球蛋白5的抑制剂。尽管该化合物自 1900 年以来就已为人所知,但文献中仍然存在关于环外双键立体化学构型的普遍混淆,从而限制了该化合物及其衍生物的进一步药物开发。通过使用 NMR 和量子力学计算,这项工作将立体构型建立为 (Z) 形式,并且单个氢键的作用对于将这些类型的分子保持在单一构型中至关重要。
