Current study deals with the evaluation of indane-1,3-dione based compounds as new class of urease inhibitors. For that purpose, benzylidine indane-1,3-diones (1-30) were synthesized and fully characterized by different spectroscopic techniques including EI-MS, HREI-MS, H-1, and C-13 NMR. All synthetic molecules 1-30 were evaluated for urease inhibitory activity and showed good to moderate inhibitory potential within the range of (IC50 = 11.60 +/- 0.3-257.05 +/- 0.7 mu M) as compared to the standard acetohydroxamic acid (IC50 = 27.0 +/- 0.5 mu M). Compound 1 (IC50 = 11.60 +/- 0.3 mu M) was found to be most potent inhibitor amongst all derivatives. The key binding interactions of most active compounds within the enzyme pocket were evaluated through in silico studies.

Synthesis and characterization of 2-benzylidene-1,3-indandione derivatives as in vitro quantification of amyloid fibrils
2-benzylidene-1,3-indandione derivatives 5a–5j were synthesized as neutral fluorescence probe candidates for identification of amyloid. Among these compounds, only compound 2-(2-hydroxybenzylidene)-1,3-indandione 5a was selected for further examination, because its fluorescence intensity showed the significant increasing upon interaction with amyloid aggregates. The compound 5a was compared to standard and conventional
