CC chemokine receptor 3 (CCR3) is expressed selectively in eosinophils, basophils, and some Th2 cells and plays a major role in allergic diseases. A methanol extract from the arils of Myristica fragrans inhibited CC chemokine ligand 11-induced chemotaxis in CCR3-expressing L1.2 cells at 100 μg/mL. From this extract, eight new neolignans, maceneolignans A–H (1–8), were isolated, and their stereostructures
CC趋化因子受体3(CCR3)在嗜酸性粒细胞,嗜碱性粒细胞和某些Th2细胞中选择性表达,并在变应性疾病中起主要作用。在100μg/ mL的表达CCR3的L1.2细胞中,从肉豆蔻的假种皮中提取甲醇可抑制CC趋化因子配体11诱导的趋化性。从该提取物中分离出了八种新的新木脂素,即美耐木聚糖A–H(1 – 8),并从其光谱值和化学性质阐明了它们的立体结构。那些成分,化合物1,4,6,和8和(+) -赤- (7小号,8 - [R)-Δ 8'-7-羟基-3,4-亚甲二氧基-3',5'-二甲氧基- 8- ö -4'-新木脂素(11),( - ) - (8 - [R)-Δ 8' -3,4-亚甲二氧基3',5'-二甲氧基-8 - O -4'-neolignan(17),(+)-licarin A(20),nectandrin B(25),verrucosin(26)和myristicin(27)抑制CCR3
