Mb. Andrus et al., Synthesis and analysis of polyethylene glycol linked P-glycoprotein-specific homodimers based on (-)-stipiamide, TETRAHEDR L, 42(23), 2001, pp. 3819-3822
A series of five homodimeric polyethylene glycol (PEG) linked homodimers ba
sed on the multidrug resistance reversal agent (-)-stipiamide were made and
tested fur their ability to interact with P-glycoprotein, the protein resp
onsible for multidrug resistance, using ATPase and photoaffinity displaceme
nt assays. Key reactions include a new alkoxide-mesylate displacement for t
he assembly of the PEG linkers and a double Sunogashira coupling reaction.
