Synthesis, Biological Activity, and Quantitative Structure−Activity Relationship Study of Azanaphthalimide and Arylnaphthalimide Derivatives
摘要:
A series of quinoline derivatives as aza analogues of the naphthalene chromophore and a series of "nonfused" tricyclic aromatic systems, in particular 5-arylquinolines and 5- or 6-aryl and heteroaryl naphthalene systems, were synthesized and evaluated for growth-inhibitory properties in several human cell lines. The analysis of quantitative structure-antitumor activity relationships for the growth-inhibitory properties is also reported. Findings suggest that these compounds may not express their cytotoxicity via interaction on DNA.

synthesized as a turn-on fluorescentsensor for Cd2+. Under physiological conditions, BNA could distinguish Cd2+ from Zn2+, showing turn-on fluorescence behaviour and an increased fluorescence lifetime. BNA and Cd2+ formed a 1 : 1 stoichiometric complex, and the detection limit was measured to be as low as 11 nM. Furthermore, BNA was utilized for fluorescence imaging of Cd2+ in live cells.
