  A New Method for the Synthesis of Heptamethine Cyanine Dyes: Synthesis of New Near-Infrared Fluorescent Labels

  摘要：

  A new uncatalyzed synthesis of heptamethine cyanine dyes is described. The reaction involves heating a mixture of N-alkyl-substituted quaternary salts derived from 2,3,3-trimethylindole or 2,3,3-trimethylbenzindole and 2-chloro-1-formyl-3-(hydroxymethylene)cyclohex-1-ene to reflux in a mixture of 1-butanol and benzene (7:3) as solvent. No catalyst is used, and water is removed as an azeotrope. The resulting chloro compounds possess strong absorption and fluorescence properties in the near-infrared region and are converted to dyes bearing reactive functionalities such as hydroxy and isothiocyanate groups useful as fluorescent tags for nucleic acids and proteins. Several symmetric and nonsymmetric dyes have been synthesized in high yields.

  Embodiments provide dual modality probes for imaging phosphatidylserine (PS) exposure and other anionic membrane surfaces. In various embodiments, the probes were constructed by utilizing a) the high selectivity of synthetic zinc (II) dipicolylamine coordination complexes (Zn-DPA) for targeting externalized PS which over-expresses in apoptotic and necrotic cells, b) a near-infrared (NIR) dye for optical imaging, and c) a widely used clinically approved radionuclide for PET (or SPECT) imaging. A variety of linking elements were incorporated into the probes between the Zn-DPA and radionuclide motif to modulate the pharmacokinetics. The in vitro and in vivo data of radiolabeled dipicolylamine probes demonstrated their utilities for imaging PS exposure with multiple imaging modalities.

  实施例提供了用于成像磷脂酰丝氨酸（PS）暴露和其他阴离子膜表面的双模探针。在各种实施例中，探针是通过利用a）合成锌（II）二吡啶胺配位配合物（Zn-DPA）对外显PS的高选择性，该PS在凋亡和坏死细胞中过度表达，b）用于光学成像的近红外（NIR）染料，以及c）用于PET（或SPECT）成像的广泛使用的临床批准放射性核素来构建的。在探针中，Zn-DPA和放射性核素基序之间结合了各种连接元素以调节药代动力学。放射性标记的二吡啶胺探针的体外和体内数据证明了它们在多种成像模式下成像PS暴露的效用。

  An optical imaging probe was synthesized by attaching a near-infrared carbocyanine fluorophore to an affinity group containing two zinc(II) dipicolylamine (Zn-DPA) units. The probe has a strong and selective affinity for the surfaces of bacteria, and it was used to image infections of Gram-positive S. aureus and Gram-negative E. coli bacteria in living nude mice. After intravenous injection, the probe selectively accumulates at the sites of localized bacterial infections in the thigh muscles of the mice.
