In the search for potential immunosuppressive agents with high efficacy and low toxicity, a series of new deoxybenzoins were synthesized and evaluated for their cytotoxicity and immunosuppressive activity. Among the synthesized compounds, four deoxybenzoin oximes (compounds 31, 32, 37, and 38) exhibited lower cytotoxicity and higher inhibitory activity toward anti‐CD3/anti‐CD28 co‐stimulated T‐cell
在寻找具有高功效和低毒性的潜在免疫抑制剂时,合成了一系列新的脱氧安息香素,并对其细胞毒性和免疫抑制活性进行了评估。中合成的化合物,四克脱氧安息香肟(化合物31,32,37,和38)表现出较低的毒性和更高的抑制活性比对其他化合物的抗CD3 /抗CD28共刺激的T细胞增殖。更重要的是,化合物31的细胞毒性比环孢菌素A(CsA)低100倍以上,而且效力更高(31:SI> 684.64,CsA:SI = 235.44)。化合物31的初步抑制机理还通过流式细胞术鉴定了这种化合物,该化合物通过以剂量依赖的方式诱导活化的淋巴结细胞凋亡来发挥免疫抑制活性。另外,通过蛋白质印迹分析检测凋亡的机制。
