Here we report a scalable synthesis of the key amino acid residue, (2,3,4)-4,5-dihydroxyisoleucine (DHIle) in α-amanitin, that in turn enables the scalable synthesis of an equipotent analogue, Asn-S,6'-dideoxy-α-amanitin, suitable for CuAAC conjugation to empower studies on therapeutic antibody-drug conjugates.
在这里,我们报告了关键氨基酸残基(2,3,4)-4,5-二羟基异亮氨酸(DHIle)在α-鹅膏蕈碱中的可扩展合成,这反过来又使等效力的类似物Asn-S,6'-去氧-α-鹅膏蕈碱的可扩展合成成为可能,适合 CuAAC 共轭,以支持治疗性抗体药物偶联物的研究。
