Thiophene and furan appended pyrazoline receptors R1 and R2 were designed and synthesized for selective detection of Al3+ ion. Their photophysical properties were studied by UV–visible and fluorescence spectra. Surprisingly, both receptors R1 a

Inhibitory effects on neutrophils' chemotaxis, phagocytosis and production of reactive oxygen species (ROS) are among the important targets in developing anti-inflammatory agents and immunosuppressants. Eight series of chalcone derivatives including five newly synthesized series were assessed for their inhibitory effects on chemotaxis, phagocytosis and ROS production in human polymorphonuclear neutrophils (PMNs). Inhibition of PMNs' chemotaxis and phagocytosis abilities were investigated using the Boyden chamber technique and the Phagotest kit, respectively, while ROS production was evaluated using luminol- and lucigenin-based chemiluminescence assay. The new derivatives (4d and 8d), which contain 4-methylaminoethanol functional group were active in all the assays performed. It was also observed that some of the compounds were active in inhibiting chemotaxis while others suppressed phagocytosis and ROS production. The information obtained gave new insight into chalcone derivatives with the potential to be developed as immunomodulators. Chalcone derivatives were synthesised and evaluated for their inhibitory effects on PMNs chemotaxis, phagocytosis and intracellular and extracellular ROS productions. It was observed that phenyl-4-methylaminoethanol and dimethoxy substituents contributed to these effects.

Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C6-C 3-C6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.
