JRC QSAR Model Database
(Q)SAR Model Reporting Format Inventory
In the regulatory assessment of chemicals (e.g. under REACH), Quantitative Structure Activity Models (QSAR) are playing an increasingly important role in predicting properties for hazard and risk assessment. This implies both a need to be able to identify relevant QSARs and to use them to derive estimates and/or have access to their precalculated estimates. To help meet these needs, the JRC QSAR Model Database is established and freely accessible through http://qsardb.jrc.ec.europa.eu/qmrf The QSAR Model Reporting Format (QMRF) is a harmonised template for summarising and reporting key information on QSAR models, including the results of any validation studies. ... -

CAMPARI
Software for molecular simulations and trajectory analysis
We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and... -

HostDesigner
General purpose de novo molecular design software
Although many potential applications exist in chemistry and material science, software to allow the general application of de novo structure-based design methods in supramolecular chemistry was non-existent. To address this limitation we created HostDesigner, a code that builds and evaluates millions of molecules in minutes. This command line executable builds 3D molecular structures by covalently connecting user-defined input fragments with pre-computed hydrocarbon fragments from a library. ... -

QUDeX-MS
Hydrogen/deuterium exchange estimation for isotopic fine structure MS
Hydrogen-deuterium exchange coupled to mass spectrometry permits analysis of structural dynamics, stability, and molecular interactions of proteins. Resolving isotopic fine structure during mass spectrometry has been recently demonstrated to allow direct detection and quantification of deuterium incorporation distinct from peaks corresponding to non-deuterium incorporated natural abundance heavy isotopomers. Here, we present a graphical tool that allows for a rapid and automated estimation of deuterium incorporation from a spectrum with isotopic fine structure resolved. ... -
