“…2,3 The molecule of ciprofloxacin is composed of three cyclic moieties, but previous 1 H and 13 C NMR studies described exactly only the members of the quinolinone moiety. 4,5 This led us to the re-examination of the 1 H NMR spectra of ciprofloxacin as a starting point for the analysis of the 1 H-15 N HMQC spectra. Additionally, encouraged by a referee, we also completed the 13 C NMR assignment.…”

Um dos ligantes da esfera de coordenação da platina pode ser trocado por um solvente dimetilsulfóxido, o que resulta em uma nova espécie (MA et al, 2010;MARTINS et al, 2001 Considerando a atividade e a seletividade do complexo IV, especialmente no que diz respeito às células MDA-MB-231, por serem células mais agressivas e que possuem caráter metastático, a continuidade dos estudos com este composto possui alta probabilidade, e assim se teve interesse em realizar a determinação do modo de morte celular para os três complexos estudados.…”
