Synthesis and biological evaluation of fluorinated N -benzoyl and N -phenylacetoyl derivatives of 3-(4-aminophenyl)-coumarin-7- O -sulfamate as steroid sulfatase inhibitors
In the present work, we report convenient methods for the synthesis of 3-(4-aminophenyl)-coumarin-7-O-sulfamate derivatives N-acylated with fluorinated analogues of benzoic or phenylacetic acid as steroid sulfatase (STS) inhibitors. The design of these potential STS inhibitors was supported by molecular modeling techniques. Additionally, computational docking methods were used to determine the binding

properties and aggregation-induced emission (AIE) activities, but the AIE characteristics of them were entirely different. HNC exhibited an AIE phenomenon as the result of the restriction of twistedintramolecular charge transfer (TICT), while DNC emitted peculiar dual fluorescence which was assigned to the emission based on the inhibition of TICT state formation and the emission from the TICT state respectively
A fluorescent probe for binding to and detection of AP sites of DNA includes the following formula: F-L-X where F is a fluorescent moiety, X is an aminooxy group (—ONH2), and L is a linker that links or couples the fluorescent moiety to the oxyamine.
