Publication for Quantitative Estimation of Drug-likeness

QED citations


Automatic Chemical Design Using a Data Driven Continuous Representation of Molecules

PMCID: 5833007
PMID: 29532027
DOI: 10.1021/acscentsci.7b00572

[…] m 400 decoding attempts from the latent space points encoded from the same 1000 seed molecules. We compare the water–octanol partition coefficient (logP), the synthetic accessibility score (SAS), and Quantitative Estimation of Drug-likeness (QED), which ranges in value between 0 and 1, with higher values indicating that the molecule is more drug-like. SI3 Figure 2 shows histograms of the propertie […]


Synthesis, characterization and in vitro antitrypanosomal activities of new carboxamides bearing quinoline moiety

PLoS One
PMCID: 5764481
PMID: 29324817
DOI: 10.1371/journal.pone.0191234
call_split See protocol

[…] The drug-likeness was predicted using online quantitative estimation of drug-likeness tools. The prediction was based on the calculated logP, topological polar surface area (TPSA), hydrogen bond donors (HBD), hydrogen bond acceptor (HBA), number […]


Application of Generative Autoencoder in De Novo Molecular Design

Mol Inform
PMCID: 5836887
PMID: 29235269
DOI: 10.1002/minf.201700123

[…] RNN with a reinforcement learning method, deep Q‐learning, to train models that can generate molecular structures with desirable property values for cLogP and quantitative estimate of drug‐likeness (QED). Olivecrona et al. proposed a policy based reinforcement learning approach to tune the pretrained RNNs for generating molecules with user defined properties. The method has been successfully appl […]


Chemometric Evaluation of THz Spectral Similarity for the Selection of Early Drug Candidates

Sci Rep
PMCID: 5674078
PMID: 29109507
DOI: 10.1038/s41598-017-14819-6

[…] and partial least squares regression (PLS). Using PCA, we projected the provided a priori molecular descriptors based on the Lipinski’s Rule of Five and the quantitative estimate of drug-likeliness (QED) onto 2D space, detecting that only two variables were responsible for >95% of the data variance: the melting point and molecular mass. Next, we applied the PCA method to the acquired THz spectra […]


An iterative compound screening contest method for identifying target protein inhibitors using the tyrosine protein kinase Yes

Sci Rep
PMCID: 5607274
PMID: 28931921
DOI: 10.1038/s41598-017-10275-4
call_split See protocol

[…] e SAR model were selected, followed by a filtering of drug-likeness and diverse selection.G3: Compounds that were physicochemically similar to those of known inhibitors were filtered using a modified QED. A randomized tree model was built on the bases of the concatenated descriptors of known inhibitors, their target kinases, and experimental conditions (concentration of reagents) and was applied t […]


Molecular de novo design through deep reinforcement learning

J Cheminform
PMCID: 5583141
PMID: 29086083
DOI: 10.1186/s13321-017-0235-x

[…] RNN as well as an RL only approach. They later extend this method to several other tasks including the generation of chemical structures, and optimize toward molecular properties such as cLogP [] and QED drug-likeness []. However, they report that the method is dependent on a reward function incorporating handwritten rules to penalize undesirable types of sequences, and even then can lead to explo […]
