We discovered that majusculamide A (1) and majusculamide B (2), isolated from a marine cyanobacterium collected in Okinawa, induced osteoblast differentiation in MC3T3-E1 cells. Although majusculamide A (1) has a different configuration only at the C-19 stereocenter, bearing a methyl group, compared to majusculamide B (2), the effect of 1 was stronger than that of 2. We synthesized some analogues of
我们发现从在冲绳收集的海洋蓝藻中分离的majusculamide A ( 1 ) 和 majusculamide B ( 2 ) 诱导 MC3T3-E1 细胞中的成骨细胞分化。尽管majusculamide A ( 1 ) 仅在C-19 立体中心具有不同的构型,带有甲基,但与majusculamide B ( 2 )相比,1的作用强于2。我们合成了 majusculamides 的一些类似物 ( 3 – 15) 并评估这些类似物的成骨活性。majusculamide类似物的结构-活性关系研究表明的甲基和配置在C-19和数量的取代基的在C-20 majusculamide A(的性质1)可以是用于的成骨细胞分化诱导作用重要1。
