In this study, some 1-methylene-2,3-diaryl-1,2-dihydropyrazino[1,2-a]benzimidazole and some 1-(2-arylvinyl)-3-arylpyrazino[1,2-a]benzimidazole derivatives were synthesised. The structure elucidation of the compounds was performed by IR, 1H-NMR and MASS spectroscopic data and elemental analyses results. Anticancer and anti-HIV activities of the compounds were examined, however no anti-HIV activity was

Abstract A series of chiral morpholino [4, 3-a] benzimidazole derivatives were synthesized effectively from (S)-(-)-2-(α-hydroxyethyl)-benzimidazole and phenacyl bromide derivatives using an efficient synthetic protocol in good yields and moderate diastereoselectivities. The substrate controlled diastereoselective route makes available structurally attractive morpholine-fused benzimidazole derivatives

High-throughput screening identified a low molecular weight antagonist of CXCR3 displaying micromolar activity in a membrane filtration-binding assay. Systematic modi. cation of the benzimidazole core and tethered acetophenone moiety established tractable SAR of analogs with improved physicochemical properties and sub-micromolar activity across both human and murine receptors.
