  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。

  and synthesized a small library of protein tyrosine phosphatase (PTP) inhibitors, in which the so-called "click chemistry" or Cu(I)-catalyzed 1,3-dipolar alkyne-azide coupling reaction was carried out for rapid assembly of 66 different bidentate compounds. Subsequent in situ enzymatic screening revealed a potential PTP1B inhibitor (IC(50) = 4.7 microM) which is 10-100 fold more potent than other PTPs

• Chemoselective reduction and self-immolation based FRET probes for detecting hydrogen sulfide in solution and in cells

  DOI：10.1039/c4ob00923a

  日期：——

  Hydrogen sulfide (H2S) has been regarded as the third gaseous transmitter. Based on the mechanism of chemoselective azido reduction and self-immolation, five fluorescence resonance energy transfer (FRET) probes for the detection of H2S were designed and synthesized. The effect of functional substitution of the self-immolative moiety on azido reduction and quinone-methide rearrangement were investigated. Their fluorescence responses and chemoselectivity for H2S detection were evaluated in solutions and in cells. This strategy may provide a general route for designing H2S probes with many commercially available FRET pairs.

  硫化氢（H2S）被视为第三种气体传递体。基于化学选择性叠氮还原和自支付机制，设计并合成了五种用于检测H2S的荧光共振能量转移（FRET）探针。研究了自支付基团的功能替代对叠氮还原和醌-美克旋转重排的影响。评估了它们在溶液和细胞中对H2S检测的荧光响应和化学选择性。这种策略可能为设计结合多种商业可用FRET对的H2S探针提供了一条通用路径。
