Salinomycin has found renewed interest as an agent for prevention of cancer recurrence through selectively targeting cancer stem cells. Strategies for generation of improved salinomycin analogs by individual modification of its hydroxyl groups are presented. An evaluation of the dose-response effects of the resulting library on breast cancer cell lines shows that acylation of the C20 hydroxyl can be
Salinomycin diastereoisomers and their benzoylated derivatives were synthesized and evaluated for both antiproliferative activity and neurotoxicity in vitro. The results indicated that the stereoscopic configurations of the spiro C17 and C21 atoms as well as the benzoyl groups of O-20 on the rigid B/C/D spiro-ketal structures are crucial for biological activity and neural toxicity. In general, there
合成了盐霉素的非对映异构体及其苯甲酰化衍生物,并评价了其体外抗增殖活性和神经毒性。结果表明,硬质B / C / D螺-缩酮结构上的螺C17和C21原子的立体构型以及O-20的苯甲酰基对于生物学活性和神经毒性至关重要。通常,这些沙利霉素衍生物的抗增殖活性与神经毒性之间存在某些正相关关系,表明可能有相似的作用机理。
