Salinomycin, a polyether antibiotic used for treatment of coccidial disease in animal husbandry, has demonstrated promising efficacy for treating different cancers. To enrich structure-activity relationship of salinomycin in tumours, we prepared a series of new triazole derivatives in specific site of salinomycin by click cycloaddition reactions, and assessed their antiproliferative activities on breast

沙利霉素三唑二聚体在ERα阳性乳腺癌细胞(MCF-7)中的毒性是天然物质的3.27-4.97倍,并且在三阴性乳腺癌细胞(
MDA-MB-231)中的毒性有所改善。
