This study aimed to identify and evaluate drug candidates targeting the kinase inhibitory region of suppressor of cytokine signaling (SOCS) 3 for the treatment of allergic rhinitis (AR). Utilizing an artificial intelligence (AI)-based new drug development platform, virtual screening was conducted to identify compounds inhibiting the SH2 domain binding of SOCS3. Luminescence assays assessed the ability of these compounds to restore JAK-2 activity diminished by SOCS3. Jurkat T and BEAS-2B cells were utilized to investigate changes in SOCS3 and STAT3 expression, along with STAT3 phosphorylation in response to the identified compounds. In an OVA-induced allergic rhinitis mouse model, we measured serum levels of total IgE and OVA-specific IgE, performed real-time PCR on nasal mucosa samples to quantify Th2 cytokines and IFN-γ expression, and conducted immunohistochemistry to analyze eosinophil levels. Screening identified 20 hit compounds with robust binding affinities. As the concentration of SOCS3 increased, a corresponding decrease in JAK2 activity was observed. Compounds and exhibited significant efficacy in restoring JAK2 activity without toxicity. Treatment with these compounds resulted in reduced SOCS3 expression and the reinstatement of STAT3 phosphorylation in Jurkat T and BEAS-2B cells. In the OVA-induced allergic rhinitis mouse model, compounds and effectively alleviated nasal symptoms and demonstrated lower levels of immune markers compared to the allergy group. This study underscores the promising nonclinical efficacy of compounds identified through the AI-based drug development platform. These findings introduce innovative strategies for the treatment of AR and highlight the potential therapeutic value of targeting SOCS3 in managing AR.
本研究旨在鉴定和评估针对细胞因子信号转导抑制因子(SOCS)3 的激酶抑制区域的药物候选物,以治疗过敏性鼻炎(AR)。利用基于人工智能(AI)的新药开发平台,进行了虚拟筛选,以鉴定抑制 SOCS3 的 SH2 结构域结合的化合物。发光测定法评估了这些化合物恢复 SOCS3 减弱的 JAK-2 活性的能力。使用 Jurkat T 和 BEAS-2B 细胞研究了鉴定的化合物对 SOCS3 和 STAT3 表达的变化,以及对 STAT3 磷酸化的影响。在 OVA 诱导的过敏性鼻炎小鼠模型中,我们测量了血清总 IgE 和 OVA 特异性 IgE 的水平,对鼻黏膜样本进行实时 PCR 以定量 Th2 细胞因子和 IFN-γ 的表达,并进行免疫组织化学分析以分析嗜酸性粒细胞水平。筛选出 20 种具有强大结合亲和力的命中化合物。随着 SOCS3 浓度的增加,JAK2 活性相应降低。化合物 和 表现出显著的恢复 JAK2 活性的功效,而没有毒性。用这些化合物处理导致 Jurkat T 和 BEAS-2B 细胞中 SOCS3 表达减少和 STAT3 磷酸化的恢复。在 OVA 诱导的过敏性鼻炎小鼠模型中,化合物 和 有效缓解了鼻症状,并且与过敏组相比,免疫标志物水平更低。本研究强调了通过基于 AI 的药物开发平台鉴定的化合物具有有前途的非临床疗效。这些发现为治疗 AR 提供了创新策略,并强调了靶向 SOCS3 管理 AR 的潜在治疗价值。
