A series of 1,3-benzothiazinone derivatives were designed and synthesized for pharmacological assessments. Among the synthesized 19 compounds, some compounds showed high activities on inhibiting LPS-induced nitrite oxide and TNF-α production, down-regulating COX-2 and increasing IL-10 production in RAW264.7 cells. All the compounds had no obvious cytotoxicity in in vitro assay. LD50 value of compound
设计并合成了一系列1,3-苯并噻嗪酮衍生物用于药理评估。在合成的19种化合物中,某些化合物在RAW264.7细胞中具有抑制LPS诱导的亚硝酸盐和TNF-α产生,下调COX-2并增加IL-10产生的高活性。在体外试验中,所有化合物均无明显的细胞毒性。化合物25的LD50值大于2000 mg / kg,比美洛昔康更安全。化合物25在LPS诱导的RAW264.7细胞中显着抑制NF-κB和STAT3的磷酸化。合成的化合物对COX活性的抑制作用比美洛昔康弱。化合物25显示出比美洛昔康更低的胃肠道毒性。此外,化合物25减少了角叉菜胶诱发的足爪水肿模型的肿胀,并显着降低了PGE2水平。
