A comprehensive map of molecular drug targets

…, B Al-Lazikani, A Hersey, TI Oprea… - Nature reviews Drug …, 2017 - nature.com
The success of mechanism-based drug discovery depends on the definition of the drug
target. This definition becomes even more important as we try to link drug response to genetic …

…, IV Tetko, D Filimonov, V Poroikov, TI Oprea… - Chemical Society …, 2020 - pubs.rsc.org
… It's that the chemists who use machines will replace those that don’t”! We hope that this
paper will stimulate experimental scientists to consider deeper integration of computational …

Estrogen signaling through the transmembrane G protein–coupled receptor GPR30

…, JB Arterburn, HO Smith, TI Oprea… - Annu. Rev …, 2008 - annualreviews.org
Steroids play an important role in the regulation of normal physiology and the treatment of
disease. Steroid receptors have classically been described as ligand-activated transcription …

Is there a difference between leads and drugs? A historical perspective

TI Oprea, AM Davis, SJ Teague… - Journal of chemical …, 2001 - ACS Publications
To be considered for further development, lead structures should display the following
properties: (1) simple chemical features, amenable for chemistry optimization; (2) membership to …

The design of leadlike combinatorial libraries

…, AM Davis, PD Leeson, T Oprea - Angewandte Chemie …, 1999 - Wiley Online Library
The optimization of low‐potency leads into drugs is often accompanied by an increase in
molecular weight (M r ) and lipophilicity, as a consequence of affinity enhancement. Hits with …

Virtual and biomolecular screening converge on a selective agonist for GPR30

…, NP Savchuck, LA Sklar, TI Oprea… - Nature chemical …, 2006 - nature.com
… Whereas 17β-estradiol initiates a very rapid (t 1/2 < 2 s) rise in intracellular calcium
concentrations, G-1 produces a slower (t 1/2 ∼ 30 s) but ultimately comparable calcium increase (Fig…

Property distribution of drug-related chemical databases

TI Oprea - Journal of computer-aided molecular design, 2000 - Springer
… Property distributions were analyzed using the Histogram program, written by Stefan Ervik
and Tudor Oprea. This routine performs a histogram-type of analysis on large numbers of data…

In vivo effects of a GPR30 antagonist

…, LA Sklar, HJ Hathaway, JB Arterburn, TI Oprea… - Nature chemical …, 2009 - nature.com
Estrogen is central to many physiological processes throughout the human body. We have
previously shown that the G protein–coupled receptor GPR30 (also known as GPER), in …

BDDCS, the Rule of 5 and drugability

LZ Benet, CM Hosey, O Ursu, TI Oprea - Advanced drug delivery reviews, 2016 - Elsevier
… However, we always caution that a simple four category system won't predict every interaction.
BDDCS doesn't propose that every drug in a class will be substrates or not substrates for …

BDDCS applied to over 900 drugs

LZ Benet, F Broccatelli, TI Oprea - The AAPS journal, 2011 - Springer
Here, we compile the Biopharmaceutics Drug Disposition Classification System (BDDCS)
classification for 927 drugs, which include 30 active metabolites. Of the 897 parent drugs, 78.8…
