WebJun 17, 2004 · The iron chelator, CPX, can mimic hypoxia in that it activates HIF-1α and vascular endothelial growth factor (VEGF) transcription and causes accumulation of their proteins in vitro and in vivo [14]. In this study, we found that CPX caused maximal increase (nearly 7-fold) in the HIF-1α mRNA level ( Fig. 2B ). WebMar 1, 2015 · Of the 17 iron chelators tested, six reduced cell viability of two NB cell lines with an inhibition of growth of 50% below 10 µ M; four of the six molecules—ciclopirox olamine (CPX), piroctone, 8-hydroxyquinoline, and deferasirox—were also shown to efficiently chelate intracellular iron within minutes after addition.
