Seventeen C20-O-alkyl/benzyl oxime derivatives were synthesized by a concise and effective method. Most of these derivatives showed tens to several hundred nanomolar IC50 values against HT-29 colorectal, HGC-27 gastric and MDA-MB-231 breast cancer cells, whose antiproliferative activity is 15–240 fold better than that of salinomycin. The C20-oxime etherified derivatives can coordinate potassium ions
通过简洁有效的方法合成了17种C20- O-烷基/苄基肟衍生物。这些衍生物中的大多数对HT-29结肠直肠癌、HGC-27胃癌和MDA-MB-231乳腺癌细胞显示出数十至数百纳摩尔的IC 50值,其抗增殖活性比盐霉素高15-240倍。C20-肟醚化衍生物可以配位钾离子,并进一步调节HT-29细胞中的胞质Ca 2+浓度。效力的显着提高应归因于改性衍生物更好的离子结合和转运能力。此外,C20- O-烷基/苄基肟衍生物显示出比盐霉素更好的选择性指数 (SI),表明它们具有较低的神经毒性风险。
