Background: Several series of pyrazole derivatives containing (thio) semicarbazide (4a-4h, 5a-5l, 6a-6f, 7a-7c) were designed and synthesized to screen dual inflammatory and antimicrobial activities. Methods: The products were characterized by1H NMR, 13C NMR and HRMS. In vitro LPS-induced TNF-α model and in vivo xylene-induced ear-edema model were used to evaluate their antiinflammatory activity. Their
背景:设计并合成了一系列含有(硫)氨基脲(4a-4h,5a-5l,6a-6f,7a-7c)的吡唑衍生物,以筛选双重炎症和抗菌活性。 方法:通过1 H NMR,13 C NMR和HRMS对产物进行表征。用体外LPS诱导的TNF-α模型和体内二甲苯诱导的耳水肿模型评估其抗炎活性。使用系列稀释法针对几种革兰氏阳性菌株,革兰氏阴性菌株和真菌菌株评估了它们的体外抗菌活性。 结果:生物测定表明,大多数化合物在浓度为20 µg / mL时均可显着抑制TNF-α的表达。化合物5i,6b和7b在50 mg / mL剂量下具有与参考药物地塞米松相当的体内抗炎活性。公斤。此外,几种化合物对不同菌株显示出抗菌活性,化合物5g和5h分别显示对肺炎链球菌CMCC 31968和金黄色葡萄球菌CMCC 25923的有效抑菌活性,MIC值为8 µg / mL。同时具有抗炎和抗微生物活性的化合物7b,应按原样或在衍生后进行研究。
