    除了放疗和手术等方法外,另一种治疗癌症的有效方法是使用化疗药物。虽然目前治疗癌症的药物已超过百种,但由于耐药性、副作用、选择性低和毒性大等原因,仍需要开发新的抗癌药物。苯并咪唑和苯并噻唑环系统因其不同的药理特性,成为许多重要药物的化学结构基础。由于苯并噻唑和苯并咪唑环系统具有潜在的抗癌作用,本研究合成了 8 个在同一化学结构中含有这两种环系统的新化合物。通过红外光谱、核磁共振和质谱以及元素分析数据对所获化合物的结构进行了表征。在 Caco-2 (ATCC HTB-37)、A549 (ATCC CCL-185) 和 NIH3T3 (ATCC CRL-1658) 细胞系上测试了合成化合物的细胞毒性作用。两个化合物(3c 和 3e)被确定为最有效的药物,其活性与参考药物顺铂相当。

    A series of novel 4” -O-2-arylbenzimidazolyl derivatives of clarithromycin were synthesized and evaluated. These 4” -O-2-arylbenzimidazolyl derivatives demonstrated excellent activity against erythromycin-susceptible strains and showed remarkably improved activity against erythromycin-resistant strains compared with the references. In particular, compound 7c, which possesses the terminal 2-(2-methoxyphenyl)benzimidazolyl group on the C-4” bishydrazide side chain, not only presented the most potent activity against erythromycin-susceptible Streptococcus pneumoniae ATCC49619 and Staphylococcus aureus ATCC25923, exhibiting 4-fold and 4-fold higher efficacy than the parent clarithromycin, but also displayed the highest activity against erythromycin-resistant Streptococcus pneumoniae expressing the mef gene and the erm gene, which was 133-fold and 32-fold better than clarithromycin or azithromycin, respectively.

    A simple and eco-friendly protocol for the synthesis of substituted 2-arylbenzimidazoles is described. In this process, 2-arylbenzimidazoles were prepared in the presence of a newly introduced ionic liquid prolinium nitrate [Pro]NO3 as catalyst, under solvent-free condition. This process was performed under mild condition without using any oxidant with good to excellent yields and remarkable chemoselectivity

    continuous effort to find potent BChE inhibitors for Alzheimer’s disease, a total of 22 novel benzimidazoles with diversified substitutions were synthesized and evaluated for their anticholinesterase activities in this study. Among the synthesized compounds, 2j and 3f were found to exhibit potent and selective BChE inhibition with IC50 values of 1.13 and 1.46 μM, respectively. Molecular docking studies

    In addition to methods such as radiotherapy and surgery, another effective way that is preferred for the treatment of cancer is based on the use of chemotherapeutic agents. Although there are more than hundred drugs for cancer treatment, there is still a need to develop new anticancer drugs because of reasons such as drug resistance, side effects, low selectivity and severe toxicity. Benzimidazole and benzothiazole ring systems are the basis of chemical structures of many important drugs because of their different pharmacological properties. In this work, due to potential anticancer effects of benzothiazole and benzimidazole ring systems, eight new compounds that contain both these ring systems in the same chemical structure were synthesized. The structures of obtained compounds were characterized by the IR, NMR, and mass spectroscopy and by elemental analysis data. Cytotoxic effects of the synthesized compounds were tested on Caco-2 (ATCC HTB-37), A549 (ATCC CCL-185) and NIH3T3 (ATCC CRL-1658) cell lines. Two compounds (3c and 3e) were determined as the most effective agents that showed activity comparable with that of the reference drug Cisplatin.
