contribute most to tissue deterioration in cases of ALI. In this study, we designed and synthesized a new series of thiazolo[3,2-a]pyrimidine derivatives based on a previously identified lead compound, and we evaluated their anti-inflammatory activities. Structure-activity relationship studies led to the discovery of two highly potent inhibitors. The two promising compounds were found to inhibit lipopolysaccharide
急性肺损伤(ALI)的致死率很高,白细胞介素6(IL-6)和肿瘤坏死因子-α(TNF-α)在ALI病例中对组织恶化的影响最大。在这项研究中,我们基于先前鉴定的先导化合物设计并合成了一系列新的噻唑并[3,2-a]嘧啶衍生物,并评估了它们的抗炎活性。结构-活性关系研究导致发现了两种高效抑制剂。发现这两种有前途的化合物以剂量依赖性方式抑制小鼠原发性腹膜巨噬细胞(MPM)中脂多糖(LPS)诱导的IL-6和TNF-α释放。此外,这些化合物的施用导致肺组织病理学改善并且在体内减弱了LPS诱导的ALI。综上所述,这些数据表明这些新颖的噻唑罗[3,
