    丙二酰甲基和琥珀酰基的结构和化学。寻找均质的1,2-重排
    摘要:
    丙二酰基甲基基团I [·CH 2 CH(COOEt)2 ]及其硫代酯类似物II [·CH 2 CH(COOEt)(COSEt)]是通过标准的光解法和热解法从过酸酯和溴代前体生成的。通过ESR光谱检查了I和II的结构,发现它们以优选的构象存在。然而,没有迹象表明它们通过乙氧基羧基或(乙硫基)羰基的1,2-转移到相应的琥珀酰基基团III和IV而重排。分别在低于-40°C的温度下发现。在高达140°C的较高温度下,通过对过酸酯分解进行彻底的产物分析,研究了丙二酰甲基琥珀酰重排的过程。有证据表明,在130°C的氯苯中,通过光解作用将I - III自由基重排,通过在130°C下热解将II - IV自由基重排。

    for APDC metabolism. Legumain‐activatable APDCs were as potent as their cathepsin B‐activatable analogues. The peptide sequence susceptible to legumain cleavage was optimized for further discrimination of the formation of active metabolites within tumor cells versus healthy tissues, leveraging different tissue‐specific legumain activities. Optimized APDCs with slow legumainmediated conversion reduced
    由于靶标介导的或脱靶的毒性,许多抗体-药物偶联物(ADC)在临床研究中均未达到足够的治疗窗口。为了达到更高的安全性水平,本文描述了针对实体瘤中不同靶标的新型抗体-前药偶联物(APDC)。肿瘤相关的溶酶体内肽酶legumain具有独特的裂解序列被用于APDC代谢。豆科菌素可激活的APDC与组织蛋白酶B激活类似物一样有效。优化了对豆荚菌素裂解敏感的肽序列,以利用不同的组织特异性豆荚菌素活性,进一步区分肿瘤细胞与健康组织中活性代谢产物的形成。
