compounds 3l, 3m and 3n intact mainly with Arg 44 amino acid, which may be involved in COX-2 inhibition. The compounds which bind with Arg 44 have significant anti-inflammatory activity. This could be due to the formation of more effective hydrogen bond with the receptor. Comparing pharmacological activity and docking results, we conclude that heterocyclic derivatives linked with nitrogen at 7-position of coumarin
Spin-crossover nanoparticles form homogeneous thin films on substrates, which show abrupt spin transitions with large thermal hysteresis loops.

surface analysis and fingerprint plots revealed that the [4-am-1 H -124-tr] + [NO 3 ] – structure is stabilized mainly by formation of O⋯H/H⋯O and N⋯H/H⋯Nhydrogenbonds. However, contributions from H⋯H and N⋯O/O⋯N contacts were also observed. UV– vis analysis (conducted in water-phase) clearly showed that charge transfers occurred in the title molecule. The energies of HOMO and LUMO, which were active
