亮氨酸氨肽酶(LAP)参与肿瘤细胞增殖、侵袭和血管生成,是众所周知的肿瘤标志物。近年来,化学发光因其灵敏度高、信噪比优异等优点,在生物成像领域得到了广泛的应用。在这里,我们报告了第一个用于 LAP 检测和成像的 LAP 激活化学发光探针的设计、合成和评估。该探针最初没有化学发光,但在 LAP 存在下释放二氧杂环丁烷中间体后产生了极强的化学发光。该探针比其他蛋白酶具有高选择性,并且比商业荧光团具有更高的信噪比。实时成像结果表明,注射探针后小鼠肿瘤部位的化学发光显着增强。此外,该探针在患者癌变组织中的化学发光与正常组织相比明显提高。综上所述,本研究开发了第一个可激活 LAP 的化学发光探针,可潜在用于蛋白质检测、疾病诊断和药物开发。

An objective of the present invention is to provide methods of synthesizing peptides containing structurally diverse amino acids using cell-free translation systems, which can accomplish excellent translational efficiency as compared to conventional techniques (the conventional techniques being methods which involve preparing aminoacyl-tRNAs which do not have protecting groups outside the translation systems without using ARS, and then adding the prepared aminoacyl-tRNAs into translation systems). In the present invention, it was found that amino acid-containing peptides can be synthesized efficiently by protecting an amino acid linked to tRNA with an appropriate protecting group, and then performing the step of deprotecting the protecting group of the amino acid linked to tRNA and the step of peptide translation from a template nucleic acid in a cell-free translation system in parallel.
