Vialinin A (1) is an extremely potent inhibitor against tumor necrosis factor (TNF)-α production in rat basophilic leukemia (RBL-2H3) cells. This Letter describes the design and synthesis of its advanced analog, 5′,6′-dimethyl-1,1′:4′1″-terphenyl-2′,3′,4,4″-tetraol (2) with a comparable inhibitory activity (IC50 = 0.02 nM) to that of 1. The synthesis involved double Suzuki–Miyaura coupling as a key
Vialinin A(1)是一种对大鼠嗜碱性白血病(RBL-2H3)细胞中的肿瘤坏死因子(TNF)-α产生的极强抑制剂。这封信描述了其先进的类似物5',6'-二甲基-1,1':4'1''-三联-2',3',4,4''-四醇(2)的设计和合成抑制活性(IC 50 = 0.02 nM)对1的抑制活性。合成过程涉及双Suzuki-Miyaura偶联作为关键步骤,从市售3,4-二甲基苯酚仅需五个步骤。为了鉴定靶分子,通过“点击”偶联过程制备了2的荧光和生物素化衍生物。
