Personalized medicine or precision medicine has been an emerging market for better treatments of patients under varying physiological conditions.To improve the development of personalized medicine, a higher understanding of drug-protein binding between serum transport proteins and the unbound form of pharmaceuticals is needed. Human Serum Albumin (HSA) and Alpha1-acidglycoprotein (AGP) play a crucial role in pharmacokinetics as they are two most abundant transport serum proteins in body circulatory system. Inter-individual variabilities of serum proteins, such as the physiological condition of patients, have been believed to alter the drug-serum protein binding. Fig. 1 shows an example of the cause of inter-individual …

High-performance affinity chromatography (HPAC) is a type of liquid chromatography in which solutes are separated based on their binding to a stationary phase that is a biologically-related agent. Sulfonylurea drugs have significant binding to proteins in blood, with most of this binding is believed to occur with human serum albumin (HSA). HSA is known to be modified as a result of the high serum levels of glucose that is present during diabetes, which may also alter the function of HSA as a binding agent for many drugs in circulation. Some modifications of HSA that can occur during diabetes involves early …

A number of tools based on high-performance affinity separations have been developed for studying drug-protein interactions. An example of one recent approach is ultrafast affinity extraction. This method has been employed to examine the free (or non-bound) fractions of drugs and other solutes in simple or complex samples that contain soluble binding agents. These free fractions have also been used to determine the binding constants and rate constants for the interactions of drugs with these soluble agents. This report describes the general principles of ultrafast affinity extraction and the experimental conditions under which it can be used to characterize such …
