A solid metal–organic catalyst with hydrophobic pockets and Lewis acid centers strongly accelerates the reaction rate for organic reactions. This is exemplified for the cyanosilylation of ketones and for the synthesis of benzimidazoles, for which very high selectivities are obtained. The solid can be recovered and reused and its behavior approaches that of a functional enzyme mimic.
This invention relates to a family of benzimidazole analogs, which are inhibitors of the IgF response to allergens. These compounds are useful in the treatment of allergy, asthma, or any diseases where IgE is pathogenic.

Benzimidazole analogs 1-27 were synthesized, characterized by EI-MS and H-1 NMR and their alpha-glucosidase inhibitory activities were found out experimentally. Compound 25, 19, 10 and 20 have best inhibitory activities with IC50 values 5.30 +/- 0.10, 16.10 +/- 0.10, 25.36 +/- 0.14 and 29.75 +/- 0.19 respectively against alpha-glucosidase. Compound 6 and 12 has no inhibitory activity against alpha-glucosidase enzyme among the series. Further studies showed that the compounds are not showing any cytotoxicity effect. The docking studies of the compounds as well as the experimental activities of the compounds correlated well. From the molecular docking studies, it was observed that the top ranked conformation of all the compounds fit well in the active site of the homology model of alpha-glucosidase.
