The synthesis of novel series of structurally related 1H-pyrazolyl derivatives is described. All the newly synthesized compounds were tested for their in vivo anti-inflammatory activity by two different bioassays namely; cotton pellet-induced granuloma and sponge implantation model of inflammation in rats. In addition, COX-1 and COX-2 inhibitory activities, ulcerogenic effects and acute toxicity were
描述了结构上相关的新型系列1H-吡唑基衍生物的合成。通过两种不同的生物测定法测试所有新合成的化合物的体内抗炎活性。棉丸诱发肉芽肿和海绵植入大鼠炎症模型。另外,测定了COX-1和COX-2的抑制活性,致溃疡作用和急性毒性。评价了相同的化合物对大肠杆菌的体外抗菌活性,例如革兰氏阴性细菌,金黄色葡萄球菌(例如革兰氏阳性细菌)和白色念珠菌(Candida albicans)作为真菌的代表。来自局部和全身体内动物模型的综合抗炎数据表明,化合物4、5、8、9 11和12a显示出与消炎痛相当的抗炎活性,没有或仅有最小的致溃疡作用,并且安全系数高(LD(50)> 500 mg / Kg)。此外,与氨苄西林相比,化合物4、7、10、12a和12b表现出明显的抗菌活性,尤其是针对金黄色葡萄球菌。化合物4和12a是本研究中鉴定出的最独特的衍生物,因为它们具有显着的体内和体外抗炎作用以及与氨苄青霉素抗革兰氏阳性相
