Abstract
The pharmacological effects of a drug are highly dependent on the absorption, metabolism, elimination, and distribution of the drug. In the past few years it has become apparent that transport proteins play a major role in regulating the distribution, elimination and metabolism of some drugs. As a consequence of our new understanding of the influence of transport proteins on the pharmacokinetic and pharmacodynamic behavior of drugs, increasing attention has been focused on the potential for drug-drug interactions arising from interactions with drug transport proteins. The efflux transporter P-glycoprotein (P-gp) has received the most attention with regard to its role in restricting drug absorption and distribution and as a potential source for variability in drug pharmacokinetics and pharmacodynamics. This review will focus on the evaluation of drug candidates to assess the potential for drug interactions at the level of P-gp. We will discuss the role of P-gp in drug disposition, the biochemistry of P-gp efflux as it relates to model systems to study drug interactions with P-gp, and the implementation of P-gp assay models within the drug discovery process.

Exploring oxidative stress and the anti-oxidant defense system in chronic diseases: therapeutic strategies and future perspective
Ageing is facilitated by oxidative stress (OS), which happens spontaneously. Several studies have demonstrated that OS over an extended period of time has a role in the emergence of several chronic illnesses. Diabetes, cancer, and heart disease are a few examples of these ailments. An imbalance between the body's antioxidants ...read more
Impact of brain tissue binding and plasma protein binding of drugs in DMPK
The impression of brain tissue binding (BTB) or plasma protein binding (PPB) in Drug Metabolism and Pharmacokinetics is critical to understanding the distribution, efficacy, and potential toxicity of drugs that target the central nervous system (CNS). BTB and high PPB influence the distribution of drugs in the body and their ...read more
Interaction between drugs and endocrine diseases
The introduction of highly active antiretroviral therapy accelerated studies and our understanding on the interaction between pharmacological therapies and endocrine diseases. Drugs can precipitate endocrine via different mechanisms, including direct alteration of hormone production and secretion, dysregulation of hormonal axis, effects on hormonal transport, receptor-binding, and cellular signalling. Common drug-induced ...read more
Metabolism-mediated xenobiotic toxicity
Considering the potent modulation of biotransformation enzyme expression and activities by various therapeutic drugs and environmental chemicals, and the commonly combined exposure of humans to both drugs and the ever increasing environmental pollutants simultaneously, knowledge about the combined toxic effects by modulating biotransformation enzymes, such as P450s, UDP- glucuronosyltransferases, and ...read more
