A Leonardi et al.
Il Farmaco; edizione scientifica, 36(8), 711-720 (1981-08-01)
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.
D Nardi et al.
Il Farmaco; edizione scientifica, 34(9), 789-801 (1979-09-01)
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

Oral diseases, 20(8), 809-814 (2013-12-18)
The intravenous injection of bisphosphonates, currently used for osteoporosis, myeloma, or bone metastases, can cause ONJ especially in consequence of trauma. To avoid trauma during bisphosphonate treatment, preventive oral surgery is recommended. The research aimed to evidence whether inflammatory and

Journal of inorganic biochemistry, 28(2-3), 125-135 (1986-10-01)
Solution equilibria are presented for in situ reactions of the type FeII(porp) + B----FeII(porp)B, where porp represents the dianion of some durene-capped porphyrins with variable length linking methylene straps, and B is 1-methyl, 1,2-dimethyl, or 1,5-dicyclohexylimidazole.
