  Correlating Molecular Character of NIR Imaging Agents with Tissue-Specific Uptake

  摘要：

  Near-infrared (NIR) fluorescent contrast agents are emerging in optical imaging as sensitive, cost-effective, and nonharmful alternatives to current agents that emit harmful ionizing radiation. Developing spectrally distinct NIR fluorophores to visualize sensitive vital tissues to selectively avoid them during surgical resection of diseased tissue is of great significance. Herein, we report the synthetic variation of pentamethine cyanine fluorophores with modifications of physicochemical, properties toward prompting tissue-specific uptake into sensitive tissues (i.e., endocrine glands). Tissue-specific targeting and biodistribution studies revealed localization of contrast agents in the adrenal and pituitary glands, pancreas, and lymph nodes with dependence on molecular characteristics. Incorporation of hydrophobic heterocyclic rings, alkyl groups, and halogens allowed a fine tuning capability to the hydrophobic character and dipole moment for observing perturbation in biological activity in response to minor structural alterations. These NIR contrast agents have potential for clinical translation for intraoperative imaging in the,delineation of delicate glands.

  trimethine cyanine compounds that effectively inhibit PRMT1 activity. In our present study, we systematically investigated the structure–activity relationship of cyanine structures. A pentamethine compound, E-84 (compound 50), showed inhibition on PRMT1 at the micromolar level and 6- to 25-fold selectivity over CARM1, PRMT5, and PRMT8. The cellular activity suggests that compound 50 permeated the cellular

  精氨酸甲基转移酶1（PRMT1）参与许多生物学活动，例如基因转录，信号转导和RNA处理。PRMT1的过度表达与心血管疾病，肾脏疾病和癌症有关；因此，选择性PRMT1抑制剂可作为化学探针来研究PRMT​​1的生物学功能和用于疾病治疗的候选药物。我们以前的工作发现了有效抑制PRMT1活性的三甲胺花青化合物。在我们目前的研究中，我们系统地研究了花菁结构的结构-活性关系。五甲胺化合物E-84（化合物50）在微摩尔水平上对PRMT1表现出抑制作用，其选择性是CARM1，PRMT5和PRMT8的6至25倍。细胞活性表明该化合物50渗入细胞膜，抑制细胞PRMT1活性，并阻止白血病细胞增殖。此外，我们的分子对接研究表明，化合物50可能通过占据辅因子结合位点发挥作用，这为指导进一步优化该先导化合物提供了路线图。
