A series of novel polyhalogenated 2-phenylbenzimidazoles have been synthesized and evaluated for in vitro antistaphylococcal activity against drug-resistant bacterial strains (methicillin-resistant Staphylococcus aureus, and vancomycin-resistant Enterococcus faecium. Certain compounds inhibit bacterial growth perfectly. 11 was active than vancomycin (0.78 μg/mL) with the lowest MIC values with 0.19 μg/mL against methicillin-resistant Staphylococcus aureus, 8 and 35 exhibited best inhibitory activity against vancomycin-resistant Enterococcus faecium (1.56 μg/mL). The mechanism of action for this class of compounds appears to be different than clinically used antibiotics. These polyhalogenated benzimidazoles have potential for further investigation as a new class of potent anti-methicillin-resistant Staphylococcus aureus and anti-vancomycin-resistant Enterococcus faecium agents.

Inhibition of the VEGF signaling pathway has become a valuable approach in the treatment of cancers. In this work, a series of N-(2-phenyl-1H-benzo[d]imidazol-5-yl)quinolin-4-amine derivatives were designed and identified as potent inhibitors of VEGFR-2 (

Both c-Met and VEGFR-2 are important targets for the treatment of cancers. In this study, a series of N-(2-phenyl-1H-benzo[d]imidazol-5-yl)quinazolin-4- amine derivatives were designed and identified as dual c-Met and VEGFR-2 inhibitors. Among these compounds bearing quinazoline and benzimidazole fragments, compound 7j exhibited the most potent inhibitory activity against c-Met and VEGFR-2 with IC50 of 0.05 μM and 0.02 μM, respectively. It also showed the highest anticancer activity against the tested cancer cell lines with IC50 of 1.5 μM against MCF-7 and 8.7 μM against Hep-G2. Docking simulation supported the initial pharmacophoric hypothesis and suggested a common mode of interaction at the ATP-binding site of c-Met and VEGFR-2, which demonstrates that compound 7j is a potential agent for cancer therapy deserving further researching.

6-Nitrobenzimidazole derivatives (1-30) synthesized and their phosphodiesterase inhibitory activities determined. Out of thirty tested compounds, ten showed a varying degrees of phosphodiesterase inhibition with IC50 values between 1.5 ± 0.043 and 294.0 ± 16.7 μM. Compounds 30 (IC50 = 1.5 ± 0.043 μM), 1 (IC50 = 2.4 ± 0.049 μM), 11 (IC50 = 5.7 ± 0.113 μM), 13 (IC50 = 6.4 ± 0.148 μM), 14 (IC50 = 10.5 ± 0.51 μM), 9 (IC50 = 11.49 ± 0.08 μM), 3 (IC50 = 63.1 ± 1.48 μM), 10 (IC50 = 120.0 ± 4.47 μM), and 6 (IC50 = 153.2 ± 5.6 μM) showed excellent phosphodiesterase inhibitory activity, much superior to the standard EDTA (IC50 = 274 ± 0.007 μM), and thus are potential molecules for the development of a new class of phosphodiesterase inhibitors. A structure-activity relationship is evaluated. All compounds are characterized by spectroscopic parameters.
