Characterization and optical properties of novel unsymmetrical stilbene-based 1,3,4-oxadiazole derivatives
摘要:
A series of novel unsymmetrical stilbene-based 1,3,4-oxadiazole derivatives were efficiently synthesized by a four-pots reaction sequence. All of the title compounds were characterized by MS, H-1-NMR and elemental analysis. UV-Vis absorption and fluorescence emission spectra of the compounds were investigated in dilute chloroform solution; the compounds exhibit strong blue-green fluorescence ranged from 397 to 499 nm and show potential for application in organic optical materials.

In vitro/in vivo effects of some new 2,5-disubstituted 1,3,4-oxadiazole and hydrazone analogues targeting Parkinson's disease
A series of new 1,3,4-oxadiazole 3a-3k and hydrazone hybrids 5a-5m were synthesized and their activity against both the A and B isoforms of hMAO was evaluated in vitro. The compounds were synthetically accessible in high yields by three different methods. The investigation indicated that some of them, especially 3a and 3d, exhibited effective in vitro inhibition of hMAO-B. Experimental compound 3a
