A new class of sila-substituted 1,3,4-oxadiazoles was synthesized and evaluated for antiallergic activity using RBL-2H3 as the in vitro model and the in vivo anaphylactic mouse model. We observed that compound 5c effectively suppressed DNP-HSA-induced mast cell degranulation, compared to carbon analogue 9, and also suppressed the expression of TNF-α mRNA and Akt phosphorylation in antigen-stimulated
合成了一类新型的硅烷取代的1,3,4-恶二唑,并使用RBL-2H3作为体外模型和体内过敏性小鼠模型评估其抗过敏活性。我们观察到,与碳类似物9相比,化合物5c有效抑制了DNP-HSA诱导的肥大细胞脱粒,并且还抑制了抗原刺激的RBL-2H3细胞中TNF-αmRNA的表达和Akt磷酸化。我们还研究了5c在体内被动皮肤过敏反应(PCA)小鼠模型中的作用。5c的抑制作用比典型的抗组胺药二苯氢胺(DPH)抑制作用更有效。
