2-oxo-2H-chromenyl-5-oxo-2,5-dihydrofuran-3-carboxylates (5a-n) and 2H-chromenyl-5-oxo-2,5-dihydrofuran-3-carboxylates (8a-p). All the prepared compounds were screened for anti-inflammatory activity. In vitro anti-inflammatory activity data demonstrated that the compounds 5g, 5i, 5k-l and 8f are effective among the tested compounds against TNF-α (1.108 ± 0.002, 0.423 ± 0.022, 0.047 ± 0.001, 0.070 ± 0.002
4-氯-2-氧代-2 H-亚甲基-3-甲醛(3a-g)和4-氯-2 H-亚甲基-3-甲醛(7a-h)与活化炔烃(4a-b)的环加成反应提供了2-oxo-2 H -chromenyl-5-oxo-2,5-dihydrofuran-3-羧酸盐(5a-n)和2 H -chromenyl-5-oxo-2,5-dihydrofuran-3-羧酸盐(8a -p)。筛选所有制备的化合物的抗炎活性。体外抗炎活性数据表明化合物5g,5i,5k-1和8f与标准化合物泼尼松龙(0.033±0.002 µM)相比,被测化合物对TNF-α(1.108±0.002,0.423±0.022,0.047±0.001,0.070±0.002和0.142±0.001 µM)有效。根据体外结果,已选择了三种化合物(5i,5k和8f)用于体内实验,在LPS诱导的小鼠模型中,就抗炎活性而言,这些化合物被确定为更好的化合物。化合物5
