1. Inclusion complexes and self-assembled cyclodextrin aggregates for increasing the solubility of benzimidazoles
Albendazole and fenbendazole are imidazole derivatives that exhibit broad spectrum activity against parasites, but the low solubility of these drugs considerably reduces their effectiveness. Complexation of albendazole and fenbendazole with cyclodextrins (β-cyclodextrin and hydroxypropyl-β-cyclodextrin) in both water and an aqueous solution of polyvinylpyr

2. Preparation and Luminescence Properties of Europium(III) Ternary Complex-modified Poplar Wood-based Materials
Inspired by the ultraviolet induced properties of biological materials, we developed fluorescent wood as a new type of functional material which can be applied to anti-counterfeit label technology and wood-emitting artwork. This study discusses the influence of temperature, time, ligand ratio, and reactant concentration on the structure and properties of flu

3. Mixed Ternary Mononuclear Copper(II) Complexes Based on Valproic Acid with 1,10-Phenanthroline and 2,2'-Bipyridine Ligands: DNA Interaction and Cytotoxicity in V79 Cells
This paper reports the DNA interaction and cytotoxicity of binary and ternary copper(II) complexes of valproic acid with phenanthroline or bipyridine and the complementary characterization of Cu(Valp)2Bipy by crystallography. Circular dichroism, plasmid and oligonucleotide assays have shown that the complexes interact with DNA in different manners and are ab

4. COMPLEXOS DE INCLUSÃO BINÁRIOS, TERNÁRIOS E QUATERNÁRIOS CONTENDO ÓLEO ESSENCIAL DE Lippia sidoides
The aim of this work was the production and characterization of binary, ternary and quaternary complexes based on β-cyclodextrin (β-CD) and Lippia sidoides essential oil (EO). OE:β-CD formulations at proportions of 1:10 to 2:10 (binary); added with surfactant or polymer (ternary) or with both (quaternary) were prepared and submitted to spray drying at opt

5. Synthesis and Structural Analysis of Binary and Ternary Clusters Derivatives from Mercury Bis(phenylselenolate) - Hg(SePh)2 / Síntese e Análise Estrutural de Clusters Binários e Ternários Derivados de Bis(fenilselenolato) de Mercúrio Hg(SePh)2
This work deals with the synthesis and structural analysis of binary and ternary clusters derivatives from mercury bis(phenylselenolate) - Hg(SePh)2. The reaction of Hg(SePh)2 with Mg(II), Fe(II), Co(II) and Ni(II) metal salts led to the formation of a series of binary clusters [M(DPPMO2)3][Hg4X4(SePh)6]4DMFH2O and [M(DMF)6][Hg8SeX4(SePh)12]. The reaction of

6. Ternary surface complex: coadsorption of Cu(II), Zn(II), Cd(II) and nitrilotris(methylenephosphonic) acid onto boehmite
This work studies the effect of NTMP (nitrilotris(methylenephosphonic acid)) on the adsorption of Cu(II), Zn(II), and Cd(II) onto boehmite in the pH range 5-9.5. The data were analyzed using the 2-pK constant capacitance model (CCM) assuming ternary surface complex formation. Under stoichiometric conditions, NTMP is more effective for removing Cu(II) than Zn

7. STUDY OF COPPER(II) AND ZINC(II) COMPLEXES WITH SOME POLYAMINES AND PHOSPHOCREATINE OR ATP / ESTUDO DE COMPLEXOS DE COBRE(II) E ZINCO(II) COM ALGUMAS POLIAMINAS E A FOSFOCREATINA OU O ATP
Foram estudados alguns sistemas binários de Cu(II) e Zn(II) formados com as poliaminas (PA= En, Tn, Put, Spd e Spm) e os complexos ternários (MLPA), onde L foi a PCr ou o ATP e PA uma das cinco poliaminas. O estudo foi realizado em solução aquosa por potenciometria, espectroscopia de ultravioleta-visível, Raman, RMN e RPE e cálculos de menor energia de

8. Cyclodextrins and ternary complexes: technology to improve solubility of poorly soluble drugs
Ciclodextrinas (CDs) são oligossacarídeos cíclicos, compostos por unidades D-glicopiranosídicas ligadas entre si por meio de ligações glicosídicas e sua principal propriedade está na capacidade de alterar as características físico-químicas e biológicas de fármacos com baixa solubilidade por meio da formação de complexos de inclusão fármaco:C

9. Multicomponent complex formation between pyrimethamine, cyclodextrins and water-soluble polymers
The combined effect of hydroxypropyl-β-cyclodextrin (HPβCD) and polyvinylpyrrolidone (PVP) or sodium carboxymethylcellulose (CMC) on the solubility of pyrimethamine (PYR) was studied. Equimolar PYR-HPβCD solid systems, in the presence or the absence of 0.25% (w/v) PVP or 0.10% (w/v) CMC were prepared by coevaporation or freeze-drying, and characterized by

10. Resolução da estrutura tridimensional do inibidor tríptico e quimotrípico de Vigna unguiculata em complexos binário e ternário
The inhibitor BTCI (Black-eyed Pea Trypsin and Chymotrypsin Inhibitor) was purified from Vigna unguiculata seeds and crystallized in binary complex with -trypsin and in ternary complex with - chymotrypsin and -trypsin at pH 4.5 and 7.5. The crystallographic data were collected at the National Synchrotron Light Laboratory (LNLS). The c

12. Study of complexes of cadmium with some L-amino acids and vitamin-C by voltammetric technique
Voltammetric technique was used to study the binary and ternary complexes of cadmium with L-amino acids and vitamin-C (L-ascorbic acid) at pH =7.30 ± 0.01, µ = 1.0M KNO3 at 25ºC and 35ºC.
