The present invention provides novel 1,5 and 1,3, 5 -substituted imidazole compounds of formulas (I), (IIa), (IIIb) in hydrophilic or lipophilic form, which are useful as angiotensin II AT1 receptor antagonists with sympathetic suppressant properties. In particular, the invention provides pharmaceutical compositions containing the pharmacophoric groups of Losartan and Clonidine as well compounds, processes and intermediates for preparing compounds and their use in methods of treating hypertension and cardiovascular diseases through Renin Angiotensin System (RAS) and Sympathetic System (SS). Alkylated histamine based double action Saltans are lipophilic and can act transdermally.

systematic and comprehensive arylation of the 2-phenylimidazole core was feasible, and in the context of this study new arylation methods were developed. The direct 4-arylation of free 2-phenylimidazole was achieved with iodoarenes as the aryl donors in the presence of palladium catalyst (Pd/Ph(3)P) and magnesium oxide as the base. A complete switch from C-4 to C-2' arylation was accomplished using a ruthenium
