ADME Profiling in Drug Discovery and a New Path Paved on Silica

Abstract

The drug discovery and development pipeline have more and more relied on in vitro testing and in silico predictions to reduce investments and optimize lead compounds. A comprehensive set of in vitro assays is available to determine key parameters of absorption, distribution, metabolism, and excretion, for example, lipophilicity, solubility, and plasma stability. Such test systems aid the evaluation of the pharmacological properties of a compound and serve as surrogates before entering in vivo testing and clinical trials. Nowadays, computer-aided techniques are employed not just in the discovery of new lead compounds but embedded as part of the entire drug development process where the ADME profiling and big data analyses add a new layer of complexity to those systems. Herein, we give a short overview of the history of the drug development pipeline presenting state-of-theart ADME in vitro assays as established in academia and industry. We will further introduce the underlying good practices and give an example of the compound development pipeline. In the next step, recent advances at in silico techniques will be highlighted with special emphasis on how pharmacogenomics and in silico PK profiling can enhance drug monitoring and individualization of drug therapy.

Plants Metabolites: Possibility of Natural Therapeutics Against the COVID-19 Pandemic

“…Good knowledge of the chemical composition of plants leads to a better understanding of their possible and specific medicinal value. Drug discovery and development have become a wide interdisciplinary field over recent decades and many factors are involved in the successful evolution from a bioactive compound into a potential drug [( 287 , 288 ); Figure 2 ]. When existing methods with advanced technologies are applied, it can lead to a modern revelation of drugs, benefitting medicinal purposes ( 223 , 289 ).…”

Synthesis, In Vitro Antioxidant Properties and Distribution of a New Cyanothiophene-Based Phenolic Compound in Olive Oil-In-Water Emulsions

“…This rule states that high absorption or permeation of a compound is more probable when its chemical structure fulfils two or more of the following conditions: molecular weight is less than 500 Da; no more than five hydrogen bond donors (-NH-, -OH); no more than ten hydrogen bond acceptors (-N=, -O-); and octanol–water partition coefficient not greater than 5. This study was carried out to forecast the pharmacokinetic profile, potential biological activities and toxicity of SIM-53B before it is assessed as a potential oral active drug [ 45 ]. Poor pharmacokinetic profile and toxicity are the main reasons for failures in drug discovery.…”

Benzofuranyl-2-imidazoles as imidazoline I2 receptor ligands for Alzheimer's disease

“…The drug discovery pipeline has more and more relied on in silico predictions to optimize lead compounds and reduce investments [39]. In silico ADMET prediction aims to evaluate individual ADMET behaviours of examined compounds.…”
