Effect of ionic liquids on the micellization of triblock copolymers
Os copolímeros tribloco do tipo (EO)n-(PO)m-(EO)n são compostos anfifílicos que em solução aquosa têm a capacidade de se agregarem em uma determinada concentração (cmc) ou temperatura (cmt) em condições termodinâmicas específicas. Tanto a cmc como a cmt dos copolímeros tribloco tem sido intensamente estudadas na presença de diversos aditivos, mas na atualidade estes parâmetros têm sido avaliados em novos sistemas como são os líquidos iônicos. A despeito do amplo número de cátions e ânions que podem formar líquidos iônicos, ainda são escassos os dados que permitem compreender como eles interagem com os copolímeros. Desta forma neste trabalho foi realizado um estudo termodinâmico e espectroscópico para avaliar o efeito dos líquidos iônicos imidazólicos [bmim][Cl] e [bmim][Br] e o eletrólito cloreto de sódio sobre a agregação do copolímero P123. Para as medidas da cmc foi utilizada espectroscopia de fluorescência tendo como sonda molecular o pireno e para as determinações da cmt foi utilizado um nanocalorímetro diferencial de varredura. Os resultados mostraram que o [bmim][Cl] aumenta 10,3 vezes o valor da cmc em relação ao valor obtido em solução aquosa, enquanto que a cmt para o processo de agregação sofreu uma diminuição de 10,1°C para toda a faixa de concentração utilizada de [bmim][Cl] (0- 2,8% (mol/mol)). Concluiu-se que o aumento da cmc é devido a uma maior solubilidade do copolímero devido à interação do bmim + com o segmento de PPO levando a um menor gasto de energia para formar os agregados de P123.The (EO) n -(PO) m -(EO) n triblock copolymers are amphiphilic compounds which in aqueous solution have the ability to aggregate in a concentration (cmc) or temperature (cmt) at specific thermodynamic conditions. Both the cmc and cmt have been extensively studied in the presence of various additives and these parameters have been evaluated in new systems constituted, for example, by ionic liquids. Despite the large number of cations and anions that can form ionic liquids, there are few data that allow us to understand how they interact with the copolymers. Thus, in this work was carried out a thermodynamic and spectroscopic study to evaluate the imidazole ionic liquids ([bmim][CI] and [bmim][Br]) and sodium chloride electrolyte effect on the P123 copolymer aggregation. The cmc values were obtained by fluorescence spectroscopy using pyrene as molecular probe and cmt values were determine by using a differential scanning nanocalorimeter. The results showed that the [bmim][CI] increases 10.3 times the cmc compared with the value obtained in aqueous solution, and the cmt to the aggregation process has decreased by 10.1 ° C in the [bmim][Cl] concentration range studied (0-2,8% (mol/mol)). It was concluded that the cmc is increased due to a copolymer solubility increase resulting from the interaction between the cation bmim + and PPO segment leading to a lower energetic cost to P123 to form aggregates.Conselho Nacional de Desenvolvimento Científico e Tecnológic
Kinetics and thermodynamics of bovine serum albumin interactions with Congo red dye
To optimize the therapeutic applications of Congo red (CR), a potential inhibitor of protein aggregation, the kinetics and thermodynamics of the interactions between CR and a model protein need to be understood. We used surface plasmon resonance (SPR) and fluorescence techniques to determine the dynamics and thermodynamic parameters for the formation of complexes between CR and bovine serum albumin (BSA). CR interacts with BSA through a transition complex; the activation energy for association (Eact(a)) was determined to be 35.88 kJ mol−1, while the activation enthalpy (ΔH‡), entropy (ΔS‡), and Gibbs free energy (ΔG‡) are 33.41 kJ mol−1, 0.18 J mol−1 K−1, and 33.35 kJ mol−1, respectively. When this intermediate transforms into the final CR-BSA complex, the entropy of the system increases and part of the absorbed energy is released; this process is associated with a reverse activation energy (Eact(d)) of 20.17 kJ mol−1, and values of ΔH‡, ΔS‡, and ΔG‡ of 17.69 kJ mol−1, −162.86 J mol−1 K−1, and 66.25 kJ mol−1, respectively. A comparison of the SPR and fluorescence results suggests that there is more than one site where BSA interacts with CR
