Synthesis, Structure, and Biological Activities of SomeN-(4,5-Dihydro-1H-imidazol-2-yl)-l,3-dihydrobenzimidazole Derivatives
摘要:
A series of novel N-(4,5-dihydroimidazol-2-yl)-1,3-dihydrobenzimidazole derivatives 2a-d, 3a-d and 4a-p were prepared and their structure was determined by IR and NMR spectroscopic data as well as X-ray analysis of carbonitrile 2a. The compounds were studied as potential inhibitors of the human blood platelet aggregation induced by adrenaline or ADP. Compounds of type 3 proved efficacious for the reduction of arterial blood pressure upon intravenous administration to normotensive rats.
