Splet04. avg. 2014 · In this study, doxorubicin (DOX) was conjugated to a lipophilic triphenylphosphonium (TPP) that is selectively taken up by the mitochondrial membrane of cells. This new derivative of DOX, i.e., TPP-DOX, was characterized by infrared spectroscopy (IR), nuclear magnetic resonance ((1)H NMR, (13)C NMR) … SpletThis reaction favors side product as well - triphenylphosphine oxide (TPPO). For weeks I'm desperately trying to remove this from my final product, however it gets really frustrating. What I've tried so far is to precipitate out the TPPO using hexane. Usually I boil the whole mixture in hexane, let it cool (slowly) and then filter off the crystals.
