- Avaliação do potencial das Tiazolidinedionas como estratégia terapêutica no MelanomaPublication . Espírito Santo, Margarida; De Sousa-Coelho, Ana Luísa; Ana Patrícia, PintoO melanoma é uma doença mundial que representa a forma mais agressiva de cancro da pele com incidência e mortalidade em contínuo aumento. Apesar de existirem terapêuticas direcionadas às mutações específicas no melanoma, a resistência adquirida pelos doentes ao tratamento constitui uma barreira ao sucesso da terapêutica, suscitando assim a necessidade de identificação de novos fármacos e novas opções terapêuticas. Nos últimos anos tem surgido grande interesse na potencial utilização de antidiabéticos orais, como a metformina (biguanida) no tratamento do melanoma. As tiazolidinedionas (TZDs), agonistas do receptor PPARγ, são também uma classe de fármacos utilizados no tratamento da diabetes tipo 2.
- Vanadium and Melanoma: A systematic reviewPublication . Amante, Cristina; De Sousa-Coelho, Ana Luísa; Aureliano, M.The application of metals in biological systems has been a rapidly growing branch of science. Vanadium has been investigated and reported as an anticancer agent. Melanoma is the most aggressive type of skin cancer, the incidence of which has been increasing annually worldwide. It is of paramount importance to identify novel pharmacological agents for melanoma treatment. Herein, a systematic review of publications including “Melanoma and Vanadium” was performed. Nine vanadium articles in several melanoma cells lines such as human A375, human CN-mel and murine B16F10, as well as in vivo studies, are described. Vanadium-based compounds with anticancer activity against melanoma include: (1) oxidovanadium(IV); (2) XMenes; (3) vanadium pentoxide, (4) oxidovanadium(IV) pyridinonate compounds; (5) vanadate; (6) polysaccharides vanadium(IV/V) complexes; (7) mixed-metal binuclear ruthenium(II)–vanadium(IV) complexes; (8) pyridoxal-based oxidovanadium(IV) complexes and (9) functionalized nanoparticles of yttrium vanadate doped with europium. Vanadium compounds and/or vanadium materials show potential anticancer activities that may be used as a useful approach to treat melanoma.
- Vanadium compounds therapeutic effects in melanomaPublication . Amante, Cristina I.; Aureliano, Manuel; De Sousa-Coelho, Ana LuísaPolyoxometalates are a diverse family of metal-oxo anions of early transitional metal ions in high oxidation states, including vanadium. Such compounds are gaining increasing interest in biomedicine due to their anti-cancer activity. Regarding melanoma, available therapies’ effectiveness is still currently limited, commonly leading to relapse. For this reason, it is vital to identify novel anti-cancer agents.
