  Antibody–drug conjugates (ADCs) have become an important therapeutic modality for oncology, with three approved by the FDA and over 60 others in clinical trials. Despite the progress, improvements in ADC therapeutic index are desired. Peptide-based ADC linkers that are cleaved by lysosomal proteases have shown sufficient stability in serum and effective payload-release in targeted cells. If the linker

  抗体-药物偶联物（ADC）已成为肿瘤学的重要治疗手段，其中三种已获得FDA批准，另外60多项已在临床试验中获得批准。尽管取得了进步，但仍需要改善ADC治疗指数。被溶酶体蛋白酶裂解的基于肽的ADC接头在血清中显示出足够的稳定性，并在靶细胞中有效释放有效负载。如果该接头可以被肿瘤特异性蛋白酶优先水解，则安全系数可能会提高。但是，基于肽的接头的使用限制了我们调节蛋白酶特异性的能力。在这里，我们报告新型非肽类ADC接头的结构指导发现。我们表明，含有环丁烷-1,1-二羧酸的连接子主要被组织蛋白酶B水解，而缬氨酸-瓜氨酸二肽连接子则不被水解。带有非肽接头的ADC在体内与具有二肽接头的ADC一样有效和稳定。我们的结果有力地支持了拟肽连接子的应用，并为改善ADC的选择性提供了新的机会。

  Synthetic studies on the novel fungicidal oligopeptides, echinocandins (1b and 1c), are described. The constituent amino acids 5–8 were synthesized in a stereocontrolled manner from the chiral starting materials, 5a, 6a and 7a, respectively. The coupling of these amino acids was characterized by the use of unprotected amino acid as the C-terminal and 2-pyridyl thiol ester as the N-terminal, and the
