Bastos, P.D. MarcatoAbstractBladder cancer (BC) is the 9th most common cancer in the worldwide. BC's treatment is still a challenging goal. Thereby, the screening of natural compounds as solasonine (SS) and solamargine (SM) that exhibit antitumor activity is interesting to BC therapy. This work aimed to develop natural lipid-based nanoparticles (NLN) as carrier system of S. lycocarpum's fruits alkaloidic extract (AE), rich in SS and SM, and to evaluate its antitumor activity in bladder cancer cells. The NLN-AE exhibited 56 nm of diameter, low polydispersity index with shelf life estimated of 12 months, measured by LUMiSizer®. NLN-AE showed low recrystallization index with high encapsulation efficiency of SS (86%) and SM (89%). A sustained release profile was verified after 36 h. The free AE exhibited antitumor activity in bladder cancer cells. The cell viability decreased 5.4 fold when AE was encapsulated in NLN. Thus, NLN-AE has higher anti-proliferative activity than the free AE.Graphical Abstract
