疏水溶质在水中发生强自缔合。然而,溶质自缔合往往被忽视,在了解药物的水溶性,以及它们的增溶赋形剂,助溶剂和水溶助长剂。基于严格的统计热力学基础上,在这里,我们展示了如何估计溶质自缔合溶解度和增溶的贡献,基于实验数据,如溶解度和渗透第二维里系数。这些数据表明,溶质自缔合确实可以忽略不计,在最常见的情况下,水溶增溶,Setschenow系数和疏水水化。
Strong self-association of hydrophobic solutes takes place in water. However, solute self-association has often been neglected in understanding the aqueous solubility of drugs as well as their solubilization by excipients, cosolvents and hydrotropes. Based on a rigorous statistical thermodynamic foundation, here we show how to estimate the contribution from solute self-association to solubility and solubilization, based on experimental data such as solubility and the osmotic second virial coefficients. Such data show that solute self-association can indeed be negligible in most common cases of hydrotropic solubilization, Setschenow coefficients and the hydrophobic hydration.
