inhibitor of RNA polymerase II. Following on growing interest in using this toxin as a payload in antibody-drug conjugates, herein we report the synthesis and biochemical evaluation of several new derivatives of this toxin to probe the role of the trans-hydroxyproline (Hyp), which is known to be critical for toxicity. This structure activity relationship (SAR) study represents the first of its kind to
α-鹅膏蕈素是一种从死亡蘑菇Amanita phalloides 中提取的剧毒双环八肽,是一种高度选择性的 RNA 聚合酶 II 变构抑制剂。随着人们对使用这种毒素作为抗体-药物偶联物中的有效载荷越来越感兴趣,我们在本文中报告了这种毒素的几种新衍生物的合成和生化评估,以探讨反式羟脯氨酸 (Hyp) 的作用,已知它是对毒性至关重要。这项构效关系 (SAR) 研究是同类研究中首次使用各种 Hyp 类似物来改变鹅膏蕈素中 Hyp 的构象和 H 键合特性。
