In this study, we synthesized several α- and β-anomers of dihydroergosterol (DHE)-glycosides and assessed their effects on CCL17 and CCL22 expression. We confirmed that the β-anomers of DHE-glycosides were superior to α-anomers of DHE-glycosides in inhibiting CCL17 and CCL22 mRNA and protein expression. In addition, we determined that DHE-glycoside β-anomers showed strong inhibitory activity towards
由于诸如炎症细胞因子和趋化因子的各种炎症刺激的增加,慢性皮肤炎性疾病,例如特应性皮炎,与功能障碍性皮肤屏障有关。特别地,患有慢性皮肤炎症的患者中CCL17和CCL22的表达增加。在这项研究中,我们合成了二氢麦角固醇(DHE)-糖苷的几种α-和β-端基异构体,并评估了它们对CCL17和CCL22表达的影响。我们证实,在抑制CCL17和CCL22 mRNA和蛋白质表达方面,DHE-糖苷的β-端基异构体优于DHE-糖苷的α-端基异构体。此外,我们确定DHE-糖苷β-端基异构体对刺激的HaCaT细胞中促炎性细胞因子mRNA和蛋白质表达(包括TNF-α,IL-6和IL-1β-的表达)具有很强的抑制活性。这些结果暗示在合成用于慢性皮肤发炎的药物期间应分离DHE-糖苷α-和β-端基异构体。我们的结果还表明,DHE-糖苷的β-异头物可能具有抑制皮肤炎性生物标志物蛋白CCL17和CCL22的能力,因此可作为治疗慢性皮肤炎症的新药发挥重要作用。
