Two kinds of naphthalimide derivatives were synthesized and evaluated for in vitro their anti-hepatocellular carcinoma properties. Compound 3a with a fused thiazole fragment to naphthalimide skeleton inhibited cell migration of SMMC-7721 and HepG2, and further in vivo trials with two animal models confirmed that compound 3a moderately inhibited primary H22 tumor growth (52.6%) and potently inte...

The thiourea based 4-amino-1,8-naphthalimide molecules 1-5 were designed as fluorescent anion sensors and their photophysical properties investigated upon recognition of biologically relevant anions such as acetate, dihydrogen phosphate and fluoride in DMSO. Synthesised in a single step from their respective aniline precursors, 6-9, these molecules were designed on the fluorophore-spacer-recept...

Gold(I) phosphine complexes exhibit promising properties for anticancer drug development. Here we report on a series of gold(I) phosphine complexes containing a naphthalimide ligand. Strong antiproliferative effects were observed in MCF-7 breast cancer cells as well as in HT-29 colon carcinoma cells. The cellular and nuclear gold levels were increased compared to analogues, in which the naphtha...

A molecular chemodosimeter , with a naphthalimide fluorophore connected to a newly designed phenazine energy acceptor, for the selective detection of cysteine was effectively synthesized. featured efficient intramolecular fluorescence resonance energy transfer (FRET) based on spectral overlap between the emission of naphthalimide and the absorption of phenazine. A cystamine chain with a S-S bon...

An ideal fluorescent probe should show the strongest affinity with the relevant target (binding-selectivity) by means of a selective fluorescence change (signal-selectivity). [15]aneNO(2)S(2) (1,4-dioxa-7,13-dithia-10-azacyclopentadecane) based probes usually show high binding selectivity for Ag(+) but signal selectivity for Hg(2+), because Ag(+) can quench or silence the fluorescence. To ampli...

Cell imaging: The versatile synthesis, photophysical characterization and use of multiple Cinnoline/Naphthalimide fused hybrid fluorophores for live cell imaging provides a comprehensive overview “CinNapht” potential as bio-imaging agent.

The controlling kinetics of the water solubility of two synthesized mono azo naphthalimide based disperse dyestuffs in the presence of two different dispersing agents namely Irgasol DAM and lyoprint EV agents at various temperatures were investigated. An exponential rate equation was found to describe the dissolution process. The addition of Irgasol DAM and Lyoprint EV dispersing agents increas...

A new naphthalimide derivative bearing a tetrathia-azacrown for high affinity and selective binding to Cu(+) was synthesised. Copper recognition properties in solution were evaluated using (1)H NMR and fluorescence spectroscopy. Live cell imaging by confocal microscopy highlighted the capabilities of the new sensor for the two-wavelength detection of intracellular monovalent copper in neuronal ...

The synthesis and photophysical properties of 1 and 2, two Ru(II)-polypyridyl based-1,8-naphthalimide Tröger's bases, are described; these were found to stabilize double stranded DNA, undergo rapid cellular uptake, displaying good luminescence without affecting cell viability even after 24 hours of incubation.
