Abstract in Portuguese
Este texto tem por finalidade apresentar de forma resumida e crítica a obra acadêmica da Prof.a Sofia Nikolaou, candidata ao título de Livre Docente pela Universidade de São Paulo. Para tanto, algumas de suas publicações serão apresentadas não em ordem cronológica, mas segundo um agrupamento referente a diferentes frentes de trabalho dentro de dois grandes temas: a química de coordenação de carboxilatos de rutênio e a investigação de propriedades de interesse biológico. Este último tema abrange estudos de interação dos complexos com moléculas de relevância biológica como albumina do soro humano (HSA) e o ácido desoxirribonucleico (DNA) e potenciais atividades biológicas como citotoxicidade frente a algumas linhagens de células cancerígenas, atividade antialérgica e atividade tripanocida. Serão apresentados, predominantemente, dados relativos a: (a) complexos trinucleares de rutênio com ponte µ-oxo de fórmula geral [Ru3O(CH3COO)6(L)3]PF6 nos quais L = série de ligantes azanaftalenos como a 5- bromoisoquinolina, 5-nitroisolquinolina, 5-aminoisoquinolina, isoquinolina e quinazolina ou [Ru3O(CH3COO)6(L)2(L´)]n nos quais L = série de ligantes piridínicos como a pirazina, piridina, 2,6-dimetilpiridina, 4-tercbutilpiridina, 4-acetilpiridina (4-acpy), 4-metilpiridina, 3-metilpiridina, etc; L' = moléculas funcionais como CO e NO e n = 0 ou +1; (b) complexos binucleares de rutênio com ponte µ-oxo de fórmula geral [Ru2O(carb)2(py)6](PF6)2, nos quais carb = ibuprofenato ou cetoprofenato e py = piridina; (c) complexos mononucleares homolépticos de rutênio de fórmula geral [Ru(carb)3], nos quais carb = norfloxacinato ou ciprofloxacinato. Por fim, serão apenas comentados outros trabalhos publicados pela docente que, embora foquem a química de coordenação do rutênio, não tratam necessariamente de carboxilatos ou de aspectos biológicos.

Study of some mono-, bi- and trinuclear ruthenium carboxylates: investigation of chemical aspects, interactions with biomolecules and potential biological applications

Abstract in English
This text aims to present a critical analysis of the academic work of Prof. Sofia Nikolaou during her years of teaching and researching at University of São Paulo. Therefore, her academic publications will be discussed not in chronological order, but according to a grouping related to different working fronts within two major themes: the coordination chemistry of ruthenium carboxylates and the investigation of properties of biological interest. The latter theme covers studies of the interaction of complexes with molecules of biological relevance such as human serum albumin (HSA) and deoxyribonucleic acid (DNA) and potential biological activities such as cytotoxicity against some cancer cell lines, antiallergic activity and trypanocidal activity. Data will be predominantly presented on: (a) oxo-bridge trinuclear ruthenium complexes of general formula [Ru3O(CH3COO)6(L)3]PF in which L = a series of azanaphthalene ligands such as 5-bromoisoquinoline, 5-nitroisolquinoline, 5-aminoisoquinoline, isoquinoline and quinazoline; or [Ru3O(CH3COO)6(L)2(L')] where L = a series of pyridinic ligands such as pyrazine, pyridine, 2,6-dimethylpyridine, 4-tercbutylpyridine, 4-acetylpyridine 4- methylpyridine, 3-methylpyridine, etc; L '= functional molecules such as CO and NO and n = 0 or +1; (b) oxo-bridged binuclear ruthenium complexes of the general formula [Ru2O(carb)2(py)](PF6)2, in which carb = ibuprofenate or ketoprofenate and py = pyridine; (c) ruthenium homoleptic mononuclear complexes of the general formula [Ru(carb)3], in which carb = norfloxacinate or ciprofloxacinate. Finally, other published works will be commented. These works, although focusing on the ruthenium coordination chemistry, do not necessarily deal with carboxylates or biological aspects.
