Interest in using DSC to study the interaction between different compounds and biomembrane models has increased in the last 20years. This is confirmed by the number of published research studies concerning the feasibility of investigating the behavior of different molecules, such as local anesthetics, anticancer drugs, anti-inflammatory drugs, antioxidants, antibiotics, peptides, proteins, polymers, surfactants, genetic materials, macromolecules, and also drug delivery systems (DDSs). This chapter provides a general consideration of the current applications of DSC in evaluating the interaction of different biomolecules and biomembrane models, which will be presented more thoroughly in the succeeding chapters. In particular, a detailed description of the DSC technique for studying the interaction of surfactants, genetic materials, polymers, and DDSs with biomembrane models and biomolecule toxicity studies will be provided, taking into consideration the most recent literature.

DSC studies of the interaction between drugs or other biologically active compounds with biomembrane models has often been associated or integrated with other analytical methodologies. The information gained from various techniques can depict the different and complex elements that compose such interactions. This chapter will summarize some recent examples of

DSC is a non-invasive experimental technique, which, besides other numerous applications, has been extensively applied in investigating the thermodynamic properties of synthetic and biological membranes. The calorimetric profiles of phase transitions of self-organized lipid membranes can provide valuable information about membrane interactions with biomolecules, pharmaceutical agents, other membranes, etc. The

Antimicrobial agents are from different classes of molecules that suppress multiplication and growth of or kill microorganisms such as bacteria, fungi, or viruses. The precise mechanism of action of some antimicrobial agents is unknown but they must interact with or cross the cell membrane to have an effect. Identification of

Drug Biomembrane Interaction Studies

The design and development of drugs and new pharmaceutical formulations require a full characterization of the chemical and physicochemical events occurring at the level of the single active ingredients or excipients, as well as their reciprocal interaction. Thermal analysis techniques are among the most widely used methods to achieve this;

Biological membranes consisting of two main components, lipids and proteins, have many important functions in cells. Membrane structure, physical and chemical properties of lipids and proteins, and interactions between them determine membrane functions such as the barrier separating a cell from its environment, selective transport, cell recognition, signalling and compartmentalization

This chapter will summarize recent information on cell membranes. Their structure, functions and the role of the various components are discussed, considering both their physiological tasks, such as mechanisms of drug internalization into cells, as well as membrane changes associated with or caused by particular disease states. Later chapters will

Several DSC studies have given a better understanding of the molecular mechanisms of interaction of many non-steroidal anti-inflammatory agents (NSAIDs), such as indomethacin, ibuprofen, naproxen, nimesulide, ketoprofen and oxicam drugs with cell membranes or with simplified phospholipid-based biomembrane models. The consequent changes in the organization, fluidity and permeability of these

In this chapter we briefly introduce the main physical principles of DSC as well as related techniques. After a quick survey of the more common experimental techniques, we describe the thermodynamics and kinetics of events accompanying a heating/cooling process. We focus on lipid membranes of one or more components.

DSC is a straightforward, non-perturbing thermodynamic technique first developed in the early 1960s. The large number of parameters and the high sensitivity has made DSC one of the key calorimetric tools used for investigating thermodynamic properties of biopolymers, proteins, peptides and nucleic acids. There are numerous reviews covering the different

In DSC, the heat flow in and out of a sample and a reference material is measured as a function of temperature as the sample is heated, cooled, or held isothermally at constant temperature. The measurement signal is the energy absorbed or released by the sample in milliwatts. DSC can

Barrier, reservoir, target site - those are but some of the possible functions of biological lipid membranes in the complex interplay of drugs with the organism. A detailed knowledge of lipid membranes and of the various modes of drug-membrane interaction is therefore the prerequisite for a better understanding of drug
