The total synthesis of NBRI16716B (2), a naturally occurring modulator of tumor-stroma interactions, was successfully achieved. Using this synthetic route, a dehydroxy analogue (21) and a derivative lacking the 5-hydroxy-3-methylpentenoyl side chain (22) became accessible. A preliminary structure-activity relationship study to unveil the structural requirements for selective inhibition of tumor cells
NBRI16716B(2)是肿瘤-基质相互作用的天然调节剂,已成功实现了全合成。使用该合成途径,可获得脱羟基类似物(21)和缺少5-羟基-3-甲基戊烯酰基侧链的衍生物(22)。初步的结构活性关系研究揭示了选择性抑制与基质细胞共培养的肿瘤细胞的结构要求,结果表明2的异羟肟酸酯结构都是必不可少的,而5-羟基-3-甲基戊烯酰基侧链不是必不可少的。
