Abstract
Novel fluorescent 7-methoxy- and 7-(diethylamino)-coumarins modified with azido-group on the side chain have been synthesized. Their photophysical properties and single crystals structure characteristics have been studied. In order to demonstrate the possibilities of fluorescent labeling, obtained coumarins have been tested with closo-dodecaborate derivative bearing terminal alkynyl group. CuI catalyzed Huisgen 1,3-dipolar cycloaddition reaction has led to fluorescent conjugates formation. The absorption-emission spectra of the formed conjugates have been presented. The antiproliferative activity and uptake of compounds against several human cell lines were evaluated.

Abstract
![]()
Drug-induced kidney
injury frequently leads to aborted clinical
trials and drug withdrawals. Sufficiently sensitive sensors capable
of detecting mild signs of chemical insult in cell-based screening
assays are critical to identifying and eliminating potential toxins
in the preclinical stage. Oxidative stress is a common early manifestation
of chemical toxicity, and biomolecule carbonylation is an irreversible
repercussion of oxidative stress. Here, we present a novel fluorogenic
assay using a sensor, TFCH, that responds to biomolecule carbonylation
and efficiently detects modest forms of renal injury with much greater
sensitivity than standard assays for nephrotoxins. We demonstrate
that this sensor can be deployed in live kidney cells and in renal
tissue. Our robust assay may help inform preclinical decisions to
recall unsafe drug candidates. The application of this sensor in identifying
and analyzing diverse pathologies is envisioned.
