    摘要:
    氨基磷酸酯连接体的可调性质使其作为 pH 触发的控释平台具有广泛的适用性,特别是在抗体和小分子药物缀合物(ADC 和 SMDC)的背景下,其中仍然需要新的连接体技术。在此,我们深入探索了从基于高丝氨酰的氨基磷酸酯酸可裂解接头释放开启荧光有效负载。在代表体循环、早期和晚期内体以及溶酶体的 pH 条件的缓冲液中观察到有效负载从支架释放的动力学。研究发现,有效负载释放发生在两个关键的连续步骤中:(1)P-N键水解和(2)间隔基牺牲。发现这两个步骤遵循伪一级动力学,并且对 pH 值具有相反的依赖性。 P-N 键水解随着 pH 值的降低而增加,而间隔基的牺牲在生理 pH 值下最快。尽管这两个步骤的释放动力学截然不同,但在弱酸性 pH (5.0-5.5) 下观察到最大有效负载释放,而在生理 pH 下发生最小有效负载释放。我们将此氨基磷酸酯-有效负载连接器系统集成到 PSMA 靶向荧光开启探针中,以研究表达

    The invention provides a therapeutic drug and targeting conjugate, pharmaceutical compositions containing these conjugates in pharmaceutical composition, and uses of these conjugates in anti-neoplastic and other therapeutic regimens. Also provided are novel intermediates thereof. The conjugates provide a therapeutic drug fragment or prodrug fragment bound to a targeting moiety via a linker which comprises a substrate cleavable by a protease such as Cathepsin B. The targeting moiety is a ligand which targets a cell surface molecule, such as a cell surface receptor on an anti-neoplastic cell. The ligand may function solely as a targeting moiety or may itself have a therapeutic effect. Following administration of the therapeutic drug and targeting conjugate of formula I and exposure of the conjugate to the protease specific for the substrate, the linker is cleaved and the targeting moiety is separated from the conjugate, which causes the drug fragment or prodrug fragment to convert to the drug or prodrug. The recited conjugates are useful in anti-neoplastic therapies. Also provided are methods of making the therapeutic drug and targeting conjugates and intermediates thereof, and kits comprising the therapeutic drug and targeting conjugates.
    该发明提供了一种治疗药物和靶向共轭物,包含这些共轭物的药物组合物,以及这些共轭物在抗肿瘤和其他治疗方案中的用途。还提供了其新颖的中间体。这些共轭物通过一个由蛋白酶如半胱氨酸蛋白酶B可切割的底物组成的连接物将治疗药物片段或前药片段与靶向基团结合。靶向基团是一个以细胞表面分子为靶点的配体,例如抗肿瘤细胞上的细胞表面受体。该配体可能仅作为靶向基团,也可能本身具有治疗效果。在给药公式I的治疗药物和靶向共轭物并使共轭物暴露于特异于底物的蛋白酶的情况下,连接物被切割,靶向基团与共轭物分离,导致药物片段或前药片段转化为药物或前药。所述的共轭物在抗肿瘤疗法中很有用。还提供了制备治疗药物和靶向共轭物及其中间体的方法,以及包含治疗药物和靶向共轭物的试剂盒。

For proof-of-concept, we employed such Cu(I)-BTTAA/dsProc and Cu(I)-BTTAA/dsPra pairs as a "traceless linker" strategy to construct cleavable ADCs to unleash cytotoxic compounds on cancer cells in situ, and as a "reversible modification" strategy for cell surface engineering.
