  1. 1. Salinomycin analogs : Mechanistic probes and structure–activity relationships against cancer stem cells

    Författare :Björn Borgström; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; salinomycin; semi–synthesis; ionophore properties; cancer stem cells; fluorescent probe;

    Sammanfattning : Cancer stem cells are a subpopulation of cells that possess an increased tumorigenic potential. Such cells are connected to drug resistance, metastasis, and cancer recurrence. In 2009, the polyether ionophore salinomycin was shown to exhibit selective activity against cancer stem cells. LÄS MER
