Shishijimicin A is a scarce marine natural product with highly potent cytotoxicities, making it a potential payload or a lead compound for designed antibody-drug conjugates. Herein, we describe an improved total synthesis of shishijimicin A and the design, synthesis, and biological evaluation of a series of analogues. Equipped with appropriate functionalities for linker attachment, a number of these
Shishijimicin A 是一种稀有的海洋天然产物,具有很强的细胞毒性,使其成为设计抗体-药物偶联物的潜在有效载荷或先导化合物。在此,我们描述了 shishijimicin A 的改进全合成以及一系列类似物的设计、合成和生物学评价。配备适当的接头连接功能,这些类似物中的许多都表现出极强的细胞毒性,可达到预期目的。在这些研究中开发和采用的合成策略和策略包括改进先前已知和新的磺基化试剂(如 PhthNSSMe 和相关化合物)的制备。
