A series of 2-[2-(4-cyanophenyl)-6-substituted-1H-benzimidazol-1-yl]-N-[2-(substituted)-4-oxo-1,3-thiazolidin-3-yl]acetamide [9(I-XXXI)] were synthesized. Substituted o-phenylenediamine was reacted with substituted 4-cyanobenzaldehydes in the presence of sodium metabisulfite to furnish substituted 2-(4-cyanophenyl)-1 H -benzimidazoles (1). When these substituted 2-(4-cyanophenyl)-1H-benzimidazoles were further treated with ethyl chloroacetate in KOH/DMSO, N-alkylated product (2-(4-cyanophenyl)-benzimidazol-1-yl)-acetic acid ethyl esters (2) was formed. To synthesize 2-(4-cyanophenyl)-benzimidazol-1-yl-acetic acid hydrazides (3) chemical reactions were conducted between hydrazine hydrate and the esters (2). When a mixture of 2-(4-cyanophenyl)-benzimidazol-1-yl)-acetic acid hydrazide (3) react with substituted aldehydes in ethanol was reflux, imines intermediates [4(I-XXXI) ] was formed. To synthesize 9(I-XXXI) reactions were occurred between a mixture of imine intermediate and thioglycollic acid in dioxane. The structures of newly synthesized compounds 9(I-XXXI) was confirmed by spectroscopic techniques. All the synthesized compounds were screened for its in vitro antioxidant and antiinflammatory activity. The in vitro antioxidant and antiinflammatory activity might be attributed due to the presence of more electrons withdrawing group and moiety having more lipophilicity also more electronegativity in nature.

, p. 942 - 950 (2016/08/08)
In this project, Fe3O4@SiO2 was synthesized and combined with collagen for the preparation of Fe3O4@SiO2/collagen. It was characterized by FT-IR, 1H NMR, VSM, XRD, EDX, SEM and T
Fast and efficient method for the synthesis of 2-arylbenzimidazoles using MCM-41-SO3H
Mahdavinia, Gholam Hossein,Rostamizadeh, Shahnaz,Amani, Ali Mohammad,Sepehrian, Hamid
experimental part, p. 33 - 37 (2012/07/28)
Nanosized MCM-41-SO3H material based on ordered mesoporous silica gel with covalently attached sulfonic acid groups was synthesized and used as acid catalyst for green synthesis of 2-substituted benzimidazole derivatives. Echofriendly protocol, short reaction times, easy and quick isolation of the products, and excellent yields are the main advantages of this procedure. Copyright by Walter de Gruyter.
Very fast and efficient synthesis of some novel substituted 2-arylbenzimidazoles in water using ZrOCl2?nH2O on montmorillonite K10 as catalyst
Rostamizadeh, Shahnaz,Amani, Ali Mohammad,Aryan, Reza,Ghaieni, Hamid Reza,Norouzi, Leila
experimental part, p. 547 - 552 (2010/06/16)
A simple and eco-friendly protocol for the synthesis of some novel substituted 2-arylbenzimidazoles was developed. In this process, these compounds were prepared in water as the solvent using ZrOCl2?nH 2O supported on montmorillonite K10 as an efficient water tolerating Lewis acid. The reaction was performed under mild conditions with good to excellent yields and remarkable chemoselectivity in the absence of any byproduct.
Benzimidazol-2-yl or benzimidazol-2-ylthiomethyl benzoylguanidines as novel Na+/H+ exchanger inhibitors, synthesis and protection against ischemic-reperfusion injury
Zhang, Rui,Lei, Lin,Xu, Yun-Gen,Hua, Wei-Yi,Gong, Guo-Qing
, p. 2430 - 2433 (2008/04/18)
A novel series of benzimidazol-2-yl or benzimidazol-2-ylthiomethyl benzoylguanidines were designed and synthesized as Na+/H+exchanger inhibitors. Most of them were found to inhibit NHE1-mediated platelet swelling in a concentration-dependent manner, and to have significant cardioprotective effect against myocardial ischemic-reperfusion injury, among which compounds 10a and 34 were more potent than cariporide in both in vivo and in vitro tests.
