Synthesis, characterization and cholinesterase enzymes inhibitory activity of 1-[3-methyl-5-(2,6,6-trimethyl-cyclohex-1-enyl)-4,5-dihydro-pyrazol-1-yl]-ethanone

The twisting of the cyclohexene ring relative to the pyrazole one gives rise to a medium intense intramolecular interaction of a methyl hydrogen of the former with the centroid of the latter.
