The simplified 16-membered core structures of macrosphelides were synthesized in high overall yields starting from methyl (+)- or (−)-3-hydroxybutyrate as the sole chiral source. The antiproliferative activities of these macrosphelide cores against murine colon 26-L5 adenocarcinoma cells were examined, and the results suggest that the oxygen functional groups found in the natural products are essential
从 (+)- 或 (-)-3-羟基丁酸甲酯作为唯一的手性来源,以高总产率合成了大球内酯的简化 16 元核心结构。检查了这些巨球核对鼠结肠 26-L5 腺癌细胞的抗增殖活性,结果表明在天然产物中发现的氧官能团对其生物活性至关重要。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
