Inhibiting resistance: We describe bifunctional DNA-targeting hybrid molecules that consist of a mithramycin core and a Pt complex, connected by a flexible linker. The mithramycin portion binds DNA noncovalently, whereas the Pt forms mono-adducts, intra- or interstrand DNA crosslinks. The molecules inhibit ovarian cancer cells overcoming their resistance to cisplatin.
抑制耐药性:我们描述了双功能 DNA 靶向杂合分子,该分子由
光神霉素核心和 Pt 复合物组成,通过柔性接头连接。
光神霉素部分以非共价键结合 DNA,而 Pt 形成单加合物、链内或链间 DNA 交联。这些分子可抑制卵巢癌细胞克服其对
顺铂的耐药性。
