Bengamide E (1a) and C-2 epimer (1b), free hydroxyl analogs (1c) and (1d), and shorter chain analog (1e) were synthesized by utilizing (2R,3S,4R)-2,3,4-tris(benzyloxy)hex-5-enal (2a) as the chiral building block. Preliminary biological studies revealed that only compound 1c showed slightly weaker activity than Bengamide E (1a) against MDA-MB-453 human breast carcinoma cells, MCF-7 human breast cancer
利用(2 R,3 S,4 R)-2,3合成了Bengamide E(1a)和C-2差向异构体(1b),游离羟基类似物(1c)和(1d)和短链类似物(1e)。,4-三(苄氧基)己-5-烯醛(2a)作为手性结构单元。初步生物学研究表明,只有化合物1c的活性比Bengamide E(1a)针对MDA-MB-453人乳腺癌细胞,MCF-7人乳腺癌细胞和HCT-116结肠癌细胞,其余则不起作用。这些结果表明,C-2的正确立体化学,C-2羟基的烷基化以及Bengamide E碳链的长度对于结构识别和与靶标的结合至关重要。
