A Fluorescent Probe for Rapid, High-Contrast Visualization of Folate-Receptor-Expressing Tumors In Vivo

Folate receptors (FRs) are membrane proteins involved in folic acid uptake, and the alpha isoform (FR-α) is overexpressed in ovarian and endometrial cancer cells. For fluorescence imaging of FRs in vivo, the near-infrared (NIR) region (650–900 nm), in which tissue penetration is high and autofluorescence is low, is optimal, but existing NIR fluorescent probes targeting FR-α show high non-specific tissue adsorption, and require prolonged washout to visualize tumors. We have designed and synthesized a new NIR fluorescent probe, FolateSiR-1, utilizing a Si-rhodamine fluorophore having a carboxy group at the benzene moiety, coupled to a folate ligand moiety through a negatively charged tripeptide linker. This probe exhibits very low background fluorescence and afforded a tumor-to-background ratio (TBR) of up to 83 in FR-expressing tumor-bearing mice within 30 min. Thus, FolateSiR-1 has the potential to contribute to the research in the field of biology and the clinical medicine.

SILICON-SUBSTITUTED RHODAMINE DYES AND DYE CONJUGATES

Silicon-substituted rhodamine compounds are disclosed herein. Also described herein are SiR dyes comprising at least one vinyl group attached to the Si atom (10 position) of the SiR dye. Derivatives, functionalized versions, conjugates, kits, related synthetic methods and uses of SiR compounds also are provided. Silicon-rhodamine (SiR) dyes can provide bright fluorescence at far red wavelengths and exhibit good photostability. The compounds described herein can be useful for fluorescent labeling and detection of biological samples.

Red Si-rhodamine drug conjugates enable imaging in GFP cells

Here we evaluated a series of Si-derivatized rhodamine (SiR) dyes for their ability to visualize a model drug in live cells. We show that a charge neutral SiR derivative (but not others) can indeed be used to follow the intracellular location of the model therapeutic drug in GFP cells.
