Algul, Oztekin published the artcileSynthesis and evaluation of antimicrobial activity of some 1,5(6)-H/or -methyl-2-substituted benzimidazole derivatives, COA of Formula: C9H10N2O, the publication is Asian Journal of Chemistry (2007), 19(4), 3085-3092, database is CAplus.

Benzimidazoles I (R = CH₂OH, CH₂NH₂, Me, Et, CH₂SH; R¹, R² = H, Me) were prepared by cyclocondensation of 1,2-benzenediamines with RCO₂H, followed, in some cases, by methylation with MeI. These compounds were tested in vitro against three Gram pos. (Enterococcus faecalis, Staphyloccus aureus and Staphyloccus epidermidis) and two Gram neg. bacteria (Escherichia coli, Pseudomonas aeruginosa). In addition, they were screened in vitro for their antifungal activities. All these compounds inhibited the growth of Gram pos. and Gram neg. bacteria at MIC values between 12.5 and 200 μg/mL and had MIC values between 50 and 200 μg/mL for the following fungi (Candida albicans, Candida krusei, Candida glabrata, Candida tropicalis and Candida parapsilosis).

Carini, David J. published the artcileNonpeptide angiotensin II receptor antagonists: the discovery of a series of N-(biphenylylmethyl)imidazoles as potent, orally active antihypertensives, Formula: C8H13ClN2O, the publication is Journal of Medicinal Chemistry (1991), 34(8), 2525-47, database is CAplus and MEDLINE.

Nonpeptide angiotensin II receptor antagonists I (R = CH₂OH, CH₂OMe, CHO; R¹ = tetrazolyl, (un)substituted triazolyl, CO₂H, CONHR², R² = OH, OMe, OCH₂Ph, SO₂Ph, NHSO₂CF₃, COCF₃, SO₂CF₃) were prepared and produced a potent antihypertensive effect upon oral administration. The acidic group at the 2′-position of the biphenyl is essential. Only ortho-substituted acids possess both high affinity for the AII receptor and good oral antihypertensive potency. The carboxylic acid group has been replaced with a variety of acidic isosteres, and the tetrazole ring was the most effective.

Carini, David J. published the artcilePart VI. Nonpeptide angiotensin II receptor antagonists: N-[(benzyloxy)benzyl]imidazoles and related compounds as potent antihypertensives, Application of (2-Butyl-4-chloro-1H-imidazol-5-yl)methanol, the publication is Journal of Medicinal Chemistry (1990), 33(5), 1330-6, database is CAplus and MEDLINE.

A series of title compounds (I, R¹ = Bu, SEt, SPr; R² = H, Cl, CH₂OH, CH₂OAc; R³ = CH₂OH, Cl, CH₂OAc, CH₂NHCO₂Me; R⁴ = CO₂H, NHSO₂CF₃; X = NHCO, CO, O, S, OCH₂ etc.; n = 0-1) was synthesized and demonstrated to be antagonists of the angiotensin II (AII) receptor. I are structurally related to the N-(benzamidobenzyl)imidazoles and extend the scope of this new class of nonpeptide AII antagonists. The amide linkage (X = NHCO) in the N-(benzamidobenzyl)imidazoles can be replaced successfully by a variety of groups (X = O, S, CO, OCH₂, CH:CH, NHCONH; n = 0-1); linkers of 0-1 atoms in length are most effective. When administered i.v. to awake renal hypertensive rats, these compounds exhibited potent antihypertensive activity.

Condensation of 2-chloromethylbenzimidazole with 2-mercaptobenzimidazole in MeOH using Et₃N as a base under reflux for 3 h yielded 2-(thiomethyl-2¹-benzimidazolyl) benzimidazole which on alkylation using two equivalent of alkylating agent in DMF as solvent and K₂CO₃ as a base using Bu₄NBr as phase transfer catalyst gave N,N¹-dialkylbisbenzimidazolesulfides. Alternatively, N,N¹-dialkylbisbenzimidazolesulfides could also be prepared by condensing N-alkyl-2-chloromethylbenzimidazole and N-alkyl-2-mercaptobenzimidazole in a single step. Using this synthetic strategy, N,N¹-unsymmetricallydialkylbisbenzimidazolesulfides were prepared either by condensing 2-chloromethylbenzimidazole with N¹-alkyl-2-mercaptobenzimidazoles under PTC conditions or by condensing 1-alkyl-2-chloromethylbenzimidazoles with N-unsubstituted-2-mercaptobenzimidazole, under PTC conditions too. Direct condensation of N-substituted-2-chloromethylbenzimidazoles with N¹-alkyl-2-mercaptobenzimidazoles also gave the products.

Kumar, N. D. Mahesh published the artcile“D-Glucose” phase transfer catalyzed synthesis of benzimidazolyl oxadiazole derivatives, Safety of 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, the publication is Pharma Chemica (2010), 2(4), 224-230, database is CAplus.

Condensation of 2-(chloromethyl)benzimidazole with 2-mercapto-1,3,4-oxadiazoles gave 2-[(5-phenyl-1,3,4-oxadiazol-2-yl)thiomethyl]-1H-benzimidazole (I). Alternatively, I was also prepared by treatment of 1,2-C₆H₄(NH₂)₂ with 1,3,4-oxadiazole-2-thioacetate under Philips conditions. Subsequent treatment with dialkyl sulfate in MeCN using D-glucose as phase-transfer catalyst (PTC) gave the corresponding N-alkylated 2-[(benzimidazol-2-ylmethyl)thio]-1,3,4-oxadiazoles. The latter were also prepared by the reaction of 2-(chloromethyl)-N-methylbenzimidazole with 2-mercapto-1,3,4-oxadiazoles. Even though, there are several other PTCs reported in literature, the authors employed D-glucose because it has got characteristics similar to that of crown ethers and polyethylene glycol. Furthermore, it is readily available, reasonably cheap, non-toxic, and eco-friendly.
