Scavenger receptor A (SRA) has been known as an immunosuppressive factor and therefore therapeutic inhibition of SRA may be potentially exploited for cancer immunotherapy. Our previously work suggested that rhein may act as an inhibitor of SRA in reversing immunosuppression of SRA during T cells activation. Herein, three deconstruction analogs of rhein, compound 1, 2, and 3, were further studied as
清道夫受体A(SRA)是一种免疫抑制因子,因此对SRA的治疗性抑制可能会被用于癌症免疫治疗。我们以前的工作表明,大黄酸可能在T细胞活化过程中逆转SRA的免疫抑制中起SRA抑制剂的作用。这里,大黄酸,化合物三个解构类似物1,2,和3,进一步研究了如SRA的抑制剂。这三种化合物,特别是化合物1,也称为天然产物丹磺隆,可增强T细胞活化,这是由白介素2(Il2)基因,IL-2蛋白的产生以及T细胞的增殖。此外,通过分子建模研究了这些化合物与SRA之间的相互作用。化合物1表现出与比较化合物SRA蛋白的富含半胱氨酸结构域的有利结合模式2和3。总而言之,这些结果将为作为SRA抑制剂的下一代大黄酸衍生物的未来设计和开发提供见识。
