A series of substituted 2-(2,3,5,6-tetramethylbenzyl)imidazolines and related compounds have been synthesized to study the steric and hydrophobic effects on the vasoactivity of the introduction of four methyl groups on the phenyl moiety. The 2-(2,3,5,6-tetramethylbenzyl)imidazoline (I) showed a high hypertensive activity

A series of N-[(2,3,4,6-tetramethylbenzoyl)alkyl]imidazoles and of N-([beta-(2,3,5,6-tetramethylphenyl)-beta-hydroxy]ethyl)imidazoles has been synthesized. All compounds were tested in mice for anticonvulsant activity against electroshock and pentylenetetrazole convulsions. These durene-derivatives showed good activity, whereas the corresponding benzene-derivatives were inactive.
