The present invention relates to esters of 2,2-dimethylpropionic acid having the general formula (I)
or pharmacological acceptable salts thereof, as well as to pharmaceutical compositions containing said compounds and having an inhibitory activity of elastase.
In order to explore and develop new anticancer agents, three series of 2-phenylbenzimidazoles, 15–46, were condensed under simple and mild conditions using sodium metabisulfite as an oxidation agent and another series, 47–55, were obtained via a reduction reaction using sodium borohydride. All the compounds synthesized were evaluated for their in vitro anticancer activities against three human cancer
为了探索和开发新型抗癌药物,利用焦亚硫酸钠作为氧化剂,在简单温和的条件下缩合了三个系列的2-苯基苯并咪唑15-46 ,并通过使用还原剂进行还原反应得到了另一个系列47-55 。硼氢化钠。评估了所有合成的化合物对三种人类癌细胞系的体外抗癌活性。新型化合物38被发现是针对A549、MDA-MB-231和PC3细胞系最有效的多癌症抑制剂(IC 50值分别为4.47、4.68和5.50 μg mL -1 )。此外,化合物40对MDA-MB-231细胞系表现出最佳IC 50值,为3.55 μg mL -1 。结果表明,向化合物37-55引入新的取代基可以提高其抗增殖活性。

A new series of 6-substituted 1H-benzimidazole derivatives were synthesized by reacting various substituted aromatic aldehydes with 4-nitro-o-phenylenediamine and 4-chloro-o-phenylenediamine through condensation using sodium metabisulfite as the oxidative reagent. The N-substituted 6-(chloro/nitro)-1H-benzimidazole derivatives were prepared from the 6-substituted 1H-benzimidazole derivatives and substituted
以焦亚硫酸钠为氧化试剂,将各种取代芳香醛与4-硝基邻苯二胺、4-氯邻苯二胺进行缩合反应,合成了一系列新的6-取代1H-苯并咪唑衍生物。 N-取代的6-(氯/硝基)-1H-苯并咪唑衍生物由6-取代的1H-苯并咪唑衍生物和取代的卤化物使用碳酸钾通过常规方法以及通过暴露于微波辐射来制备。采用微波辅助方法合成了 76 种 1 H -苯并咪唑衍生物,产率中等至优异(40% 至 99%)。化合物1d 、 2d 、 3s 、 4b和4k对大肠杆菌、粪链球菌、MSSA(甲氧西林敏感金黄色葡萄球菌菌株)和 MRSA(耐甲氧西林金黄色葡萄球菌菌株)表现出有效的抗菌活性,具有 MIC(最小抑制)与环丙沙星 (MIC = 8–16 μg mL -1 ) 相比,化合物 4k 在 2 至 16 μg mL -1之间,特别是化合物4k对白色念珠菌和黑曲霉表现出有效的真菌活性,MIC 范围在 8 至 16 μg mL -1
