a Schematic representation of polymer (pMeOx-b-pBuOx-b-pMeOx) as best solubilizer for mitotane. b Chemical structure of mitotane. c Long-term stability of mitotane formulation depending on mitotane feed concentration (polymer 10 g/l, mitotane 2–10 g/l). Data are given as means ± SD (n = 3). d Schematic illustration of thin film hydration method used for formulation development. e Cell viability and corresponding IC50 values of mitotane dissolved in ethanol (red) and as micelle formulation (blue) in NCI-H295R monolayer after incubation for 24 and 48 h (left vertical panel) and 3D tumor spheroids at 24 h and 48 (right vertical panel) (n = 3 ± SD).
