Inflammation is an important, normal, and complex host defense response to injury, autoimmune responses or infectious agents. However, chronic inflammation is associated with diseases like rheumatoid arthritis, cancers, cardiovascular diseases, diabetes, and obesity, and over 60% of deaths worldwide. Interleukine-6 is one of the key proinflammatory cytokines involved in inflammation processes and therefore
炎症是对损伤,自身免疫反应或感染因子的重要,正常和复杂的宿主防御反应。但是,慢性炎症与类风湿性关节炎,癌症,心血管疾病,糖尿病和肥胖症等疾病相关,并且与全世界60%以上的死亡有关。Interleukine-6是参与炎症过程的关键促炎细胞因子之一,因此被认为是有价值的药物靶标。我们已经制备了三种新药,分别称为取代的苯基环烷基脲(PcAUs),苯基环烷基硫脲(PcATUs)和苯基环烷基四酰胺(PcASs)。通过将3或4-叔丁基,3-或4-环己基和3-或4-碘苯胺亲核加成到合适的环烷基异氰酸酯或环烷基异硫氰酸酯来制备PcAU和PcATU。通过将上述苯胺亲二加到二乙氧基方酸中来制备PcAS。使所得的烷氧基方酸酯进一步与选择的环烷基胺反应以产生所需的PcAS。在人角质形成细胞和人皮肤成纤维细胞中评估了PcAUs,PcATUs和PcASs的抗增殖活性。除以下化合物外,大多数化合物带有3-环己基的4f,
