A series of oxazolidinone and indole derivatives were synthesized and evaluated as IL-6 signaling blockers by measuring the effects of these compounds on IL-6-induced luciferase expression in human hepatocarcinoma HepG2 cells transfected with p-STAT3-Luc. Among different compounds screened, compound 4d was emerged as the most potent IL-6 signaling blockers with IC50 value of 5.9 μM which was much better
合成了一系列恶唑烷酮和吲哚衍生物,并通过测量这些化合物对用p-STAT3-Luc转染的人肝癌HepG2细胞中IL-6诱导的萤光素酶表达的影响,将其作为IL-6信号传导阻滞剂进行评估。在筛选的不同化合物中,化合物4d成为最有效的IL-6信号传导阻滞剂,IC50值为5.9μM,远优于已知的IL-6抑制剂(+)-Madindoline A(IC50 = 21μM)。
