“…Previous studies have shown that Dp44mT also binds copper, which plays an important role in its antiproliferative activity (27,28). When Dp44mT was complexed with copper (Cu[Dp44mT]; 5 M), a marked and significant (p Ͻ 0.001) increase in LC3-II level was observed relative to that induced by Dp44mT alone (Fig.…”

“…Unlike DFO, Dp44mT forms redox-active iron or copper complexes that play key roles in its cytotoxic activity (20,(25)(26)(27)(28). In fact, Dp44mT was shown to be lysosomotropic and was retained within lysosomes due to their acidic pH and the ionization characteristics of Dp44mT (27).…”

“…A komplexek nagy száma ellenére az irodalomban elvétve található termodinamikai adat a vizes oldatbeli viselkedésükre vonatkozóan. 27 Az általunk eddig vizsgált réz(II)-TSK komplexek ugyan változatos sztöchiometriát és koordinációs módot mutatnak, viszont közös jellemzõjük, hogy vizes közegben biológiailag releváns körülmények között (pH = 7,4, mM-os koncentrációtartomány) kiemelkedõ stabilitásúak. 15,[18][19][20]22,23 A speciációt és a komplexek szerkezetét mindig pH-potenciometria, elektronspin rezonancia (ESR) spektroszkópia és UV-látható spektrofotometria kombinált használatával határoztuk meg, az egyes publikációkban megadott kísérleti körülménynek mellett.…”
