TLDR
It is shown that a model-based approach using basic biophysical principles yields good prediction of druggability based solely on the crystal structure of the target binding site and that these calculated values correlate with drug discovery outcomes.Abstract:
Lead generation is a major hurdle in small-molecule drug discovery, with an estimated 60% of projects failing from lack of lead matter or difficulty in optimizing leads for drug-like properties It would be valuable to identify these less-druggable targets before incurring substantial expenditure and effort Here we show that a model-based approach using basic biophysical principles yields good prediction of druggability based solely on the crystal structure of the target binding site We quantitatively estimate the maximal affinity achievable by a drug-like molecule, and we show that these calculated values correlate with drug discovery outcomes We experimentally test two predictions using high-throughput screening of a diverse compound collection The collective results highlight the utility of our approach as well as strategies for tackling difficult targetsread more

The influence of drug-like concepts on decision-making in medicinal chemistry
TL;DR: Analysis of recent trends reveals that the physical properties of molecules that are currently being synthesized in leading drug discovery companies differ significantly from those of recently discovered oral drugs and compounds in clinical development.

Reaching for high-hanging fruit in drug discovery at protein–protein interfaces
TL;DR: These studies discovered small molecules that bind with drug-like potencies to 'hotspots' on the contact surfaces involved in protein–protein interactions, and bind with much higher efficiencies than do the contact atoms of the natural protein partner.

Identifying and characterizing binding sites and assessing druggability.
TL;DR: A new program, called SiteMap, is presented for identifying and analyzing binding sites and for predicting target druggability, which provides quantitative and graphical information that can help guide efforts to critically assess virtual hits in a lead-discovery application or to modify ligand structure to enhance potency or improve physical properties in aLead-optimization context.

Quantifying the chemical beauty of drugs
TL;DR: The utility of QED is extended by applying it to the problem of molecular target druggability assessment by prioritizing a large set of published bioactive compounds and may also capture the abstract notion of aesthetics in medicinal chemistry.

Experimental and computational approaches to estimate solubility and permeability in drug discovery and development settings
TL;DR: Experimental and computational approaches to estimate solubility and permeability in discovery and development settings are described in this article, where the rule of 5 is used to predict poor absorption or permeability when there are more than 5 H-bond donors, 10 Hbond acceptors, and the calculated Log P (CLogP) is greater than 5 (or MlogP > 415).

TL;DR: Reduced molecular flexibility, as measured by the number of rotatable bonds, and low polar surface area or total hydrogen bond count are found to be important predictors of good oral bioavailability, independent of molecular weight.

TL;DR: In this article, the authors identify potent and selective small-molecule antagonists of MDM2 and confirm their mode of action through the crystal structures of complexes, leading to cell cycle arrest, apoptosis, and growth inhibition of human tumor xenografts.
