Abstract
Investigou-se o comportamento eletroquímico dos dímeros ciclopaladados [Pd(dmba)(mi-X)]2 [X = Cl (1), NCO (2), NCS (3), CN (4)] (dmba = N,N-dimetilbenzilamina) e do monômero [Pd(dmba)(MeCN)2][NO3] (MeCN = acetonitrila). Os resultados experimentais mostraram redução de Pd(II) para Pd(I) para os compostos 1-3, enquanto que somente para 1 observou-se a redução de Pd(I) para Pd(0) em uma única etapa. O complexo 5 mostrou redução de Pd(II) para Pd(0). Observou-se que a estabilidade eletroquímica destes compostos diminuem na seguinte ordem: [Pd(dmba)(mi-CN)]2 (4) > [Pd(dmba)(mi-NCO)]2 (2) > [Pd(dmba)(mi-SCN)]2 (3) > [Pd(dmba)(MeCN)2][NO3] (5) > [Pd(dmba)(mi-Cl)]2 (1).

Abstract
Two novel dimeric chloro-bridged complexes [Pd (p-is. TSCN) (mu-Cl)]2, 2, and [Pt (p-is. TSCN)(mu-Cl)]2, 3, where p-is. TSCN = p-isopropylbenzaldehyde thiosemicarbazone, 1, have been synthesized and characterized by IR and NMR spectroscopy. The in vitro antitumor activity shown by both compounds against several human and murine cell lines sensitive and resistant to the clinically-used drug cisplatin (cis-DDP) suggests that compounds 2 and 3 may be endowed with important anticancer properties. Thus, compounds 2 and 3 not only show IC50 values in the microM range as cis-DDP but also display cytotoxic activity in tumor cell lines resistant to this drug. The analysis of the interaction of these binuclear p-is. TSCN compounds with DNA secondary and tertiary structures indicate that they form DNA interhelical cross-links, a biochemical property that may be involved in their mechanism of action.

Abstract
Iron(II) ions react with small aggregates of cholate, glycocholate, chenodeoxycholate, and deoxycholate to form soluble and colloidal compounds. Taurocholate under conditions used does not react with the Fe2+ ion. Small aggregates of dihydroxy bile salts (predominating in the premicellar region, at concentrations of the bile salt above 1 mmol dm-3) have a larger affinity for Fe2+ compared to those formed from cholate anions. In their interactions with small aggregates of cholate anions, the Fe2+ ion shows an affinity comparable to that of Cu2+ and Cd2+ and somewhat larger than that of Zn2+. Small aggregates of cholate show a higher ability to mask Fe2+ than those of taurocholate and glycocholate. Interaction of glycocholic acid anions with Fe2+ ions is sufficient to prevent iron(II) precipitation.
