reported that 3-alkoxybenzo[b]thiophene-2-carboxamides exemplified by 1, 5-methoxy-3-(1-methylethoxy)benzo[b]thiophene-2-carboxamide, decreased the adherence of neutrophils to activated endothelial cells by inhibiting the upregulation of the adhesion molecules E-selectin and ICAM-1 on the surface of the endothelium. This finding is extended here to a series of 3-thiobenzo[b]thiophene-2-carboxamides and also
以前有报道说,以1,5-甲氧基-3-(1-甲基乙氧基)苯并[b]噻吩-2-羧酰胺为例的3-烷氧基苯并[b]噻吩-2-甲酰胺降低了中性粒细胞对活化内皮细胞的粘附通过抑制内皮细胞表面粘附分子E-选择素和ICAM-1的上调。该发现在这里扩展到一系列的3-硫代苯并[b]噻吩-2-羧酰胺以及1的杂环类似物,包括苯并呋喃,吲哚和萘。抑制E-选择蛋白和ICAM-1表达的化合物对VCAM-1的表达具有相同的作用。PD 144795,亚砜类似物1,即5-甲氧基-3-(1-甲基乙氧基)苯并[b]噻吩-2-羧酰胺1-氧化物(44)在几种炎症模型中具有口服活性。
