New Fluoranthene FLUN-550 as a Fluorescent Probe for Selective Staining and Quantification of Intracellular Lipid Droplets
摘要:
A new class of live cell permeant, nontoxic fluoranthene-based fluorescent probe (FLUN-550) having a high Stokes shift in aqueous medium has been discovered. It showed selective staining of lipid droplets (LDs, dynamic cytoplasmic organelles) at a low concentration without background noise in in vitro live cell imaging of 3T3-L1 preadipocytes, J774 macrophages, MCF7 breast cancer cells, and single-celled, parasitic protozoa Leishmania donovani promastigotes and in vivo nonparasitic soil nematode C. elegans.

The present invention relates to novel donor-acceptor fluoranthenes of the general formula I which can be used potentially in developing fluorescent probes, and a process of preparing said novel compounds. More particularly, the present invention relates to amine or alkoxy group as donor and nitrile group as an acceptor attached to the fluoranthene skeleton, processes for preparing the said compounds and their uses as fluorescent probes in chemical and biological sciences such as cell imaging applications, diagnostics, fluorescent tags and other useful applications. The compounds are prepared by reacting 2H-pyran-2-ones in isolated or rigid conformations with cyclic ketones containing methylene carbonyl moiety in the presence of a base in an organic solvent.
