Synthesis, photophysical and spectroscopic characterization of amphiphilic D-A-...
Boland, Mathilde; Pinto, Sónia; Gomes-da-Silva, Lígia C.; Pina, João; Costa, Susana P. G.; Raposo, M. Manuela M.Two positively charged amphiphilic benzothiadiazole derivatives with a Donor-Acceptor-π spacer-Acceptor structure (D-A-π-A) were developed, based on a methoxy-phenyl-benzothiadiazole model compound, by adopting methoxy-phenyl as the electron donor and 2,1,3-benzothiadiazole and 2,3-dimethylbenzothiazol-3-ium or 2,3-dimethylnaphtothiazol-3-ium iodide as combined electron acceptors. The aim of the study was to in...
Investigating the photophysical properties and biological efficacy of BODIPY de...
Gonçalves, Raquel Costa Raínha; Pinto, Sónia Catarina Silva; Pina, João; Gomes-da-Silva, Lígia C.; Costa, Susana P. G.; Raposo, M. Manuela M.The selectivity of photosensitizers for light activation is a key advantage in photodynamic therapy (PDT), allowing for precise targeting while sparing healthy cells. BODIPY derivatives have emerged as promising PDT candidates due to their tunable photophysical properties and versatile synthesis. Herein, we explore the photophysical characterization and the in vitro photodynamic activity of BODIPY analogues mes...
Impact of anti-PLK1 siRNA-containing F3-targeted liposomes on the viability of ...
Gomes-da-Silva, Lígia C.; Ramalho, José S.; Lima, M. C. P. de; Simões, Sérgio; Moreira, João N.We have previously described the development of novel sterically stabilized F3-targeted pH-sensitive liposomes, which exhibited the ability to target both cancer and endothelial cells. Herein, the therapeutic potential of those liposomes was assessed upon encapsulation of a siRNA against a well-validated molecular target, PLK1. Treatment of prostate cancer (PC3) and angiogenic endothelial (HMEC-1) cells with F3...
Towards a siRNA-containing nanoparticle targeted to breast cancer cells and the...
Gomes-da-Silva, Lígia C.; Santos, Adriana O.; Bimbo, Luís M.; Moura, Vera; Ramalho, José S.; Lima, Maria C. Pedroso de; Simões, Sérgio; Moreira, João N.The present work aimed at designing a lipid-based nanocarrier for siRNA delivery towards two cell sub-populations within breast tumors, the cancer and the endothelial cells from angiogenic tumor blood vessels. To achieve such goal, the F3 peptide, which is specifically internalized by nucleolin overexpressed on both those sub-populations, was used as a targeting moiety. The developed F3-targeted stable nucleic ...
