The total synthesis of majusculamide D (1) was achieved from commercially available materials. In addition, we synthesized eight analogues including three stereoisomers of majusculamide D that differ in the fatty acid chain. Six analogues including a simplified analogue 29 exhibited significant nanomolar-level IC50 values against Panc-1 cells in MTT assays. A preliminary SAR analysis indicated that
majusculamide D ( 1 )的全合成是由市售材料实现的。此外,我们还合成了八种类似物,包括三种脂肪酸链不同的 majusculamide D 立体异构体。在 MTT 测定中,包括简化类似物29在内的六种类似物对 Panc-1 细胞表现出显着的纳摩尔水平 IC 50值。初步的SAR分析表明majusculamide D的C 10 和C 2− C 3 不饱和双键上的羟基对于维持对Panc-1细胞的高活性以及C 40-Me 和C 42-Me基团的定向至关重要是可以忍受的。
