“…The [Cu(curcumin) 2 ] complexes [14] were most cytotoxic in cultured L929 cells and showed significant reduction in solid tumor volume in as cites tumor bearing mice. In addition, vanadyl, gallium and indium complexes of curcumin [15] have reported for medicinal applications. Curcumin metal complexes (M = Eu, Ce, La, Y, Cr, Pd) showed that curcumin coordinates with metal ions in bidentate mode in deprotonated form.…”

“…A presença da absorção em 448 cm -1 possivelmente está relacionada à formação das ligações Ga-O, pois relatos na literatura indicam que este tipo de ligação é encontrado em uma faixa de 450 a 470 cm -1 , entretanto, com outros tipos de ligantes. 10,27 Uma outra alteração é verificada na banda atribuída ao grupo carbonila que é deslocada para um menor comprimento de onda no complexo (1666 cm -1 na quercetina livre para 1650 cm -1 no complexo). Isto pode ser indicativo da coordenação do ligante ao íon metálico via oxigênio carbonílico (na posição 4 do anel C, Figura 1 um próton mais ácido comparativamente aos demais (o que o torna um quelante mais efetivo), 28,29 espera-se que seja um dos primeiros sítios, juntamente com o grupo 4-oxo, a serem envolvidos no processo de coordenação.…”
