Several thalidomide derivatives were synthesized and evaluated for their anti-inflammatory activity. Introduction of the benzyl group to the parent thalidomide is unfavorable in which 2-(1-benzyl-2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione (4a) was inactivated. However, the inhibitory activities on TNF-α and IL-6 expression in HaCaT cells were improved by the substitution of a chloro- or methoxy-
合成了几种沙利度胺衍生物并评估了它们的抗炎活性。在使2-(1-苄基-2,6-二氧代哌啶-3-基)异吲哚啉-1,3-二酮(4a)失活的情况下,将苄基引入母体沙利度胺是不利的。但是,HaCaT细胞中TNF-α和IL-6表达的抑制活性可通过在4a的苯基位置取代氯或甲氧基来提高。IL-6抑制活性按5c(69.44%)> 4c(48.73%)> 6c(3.19%)的顺序降低,表明3-取代的衍生物比4-取代的对应物更具活性,而4-取代的对应物则更具活性比2取代的对应物 其中2- [1-(3-氯苄基)-2,6-二氧代哌啶-3-基]异吲哚啉-1,发现3-dione(5c)在HaCaT细胞中抑制TNF-α和IL-6的表达的能力比沙利度胺更高,并且在10μM时未检测到明显的细胞毒性。在牛皮癣中,化合物5c在咪喹莫特刺激的模型中降低了IL-6,IL-8,IL-1β和IL-24。我们的结果表明,化合物5c是新型抗
