PhD position available at AEGIS project: AEGIS (Accelerated Early staGe drug dIScovery) is a Marie Sk?odowska -Curie Innovative Training Network (ITN) for early stage researchers (ESR) funded by the European Commission under the H2020 Programme, the EU framework programme for research and innovation. The AEGIS ITN will provide a comprehensive and cross-disciplinary structured curriculum for doctoral students in early drug discovery. A key research aim of AEGIS is improving the efficiency and success of early stage drug development by combining innovative methods and techniques to tackle difficult but promising targets (i.e. protein-protein interactions), as potentially valuable drug targets are often neglected due to the high risk associated with their validation.

The 2014 symposium, entitled Understanding Chemical-Biological Interactions, will focus on:
• Chemical-Biological Space
• Chemo- and Bioinformatics Approaches to Multi-Target (Q)SAR
• Modeling of Protein-Ligand Interactions
• Assessing Ligand Binding Kinetics
• Computational Toxicology in Drug and Chemical Safety Assessment

Tutorial on Applicability Domain: The tutorial on Applicability Domain gives an introduction to the concept of Applicability Domain (AD) and the problem of its definition. Several methods for the assessment of the AD of QSAR models are presented.   (inserted on 13/12/2012)

MATLAB routine for Distance-based optimal design: The MATLAB routine for Distance-based optimal design divides a set of molecules in two sets (a training set and a complementary set). Moreover, it can perform a random selection of an optional external set of molecules. Details on the algorithm can be found in the following paper: Marengo-Todeschini algorithm (Chemolab,16,37-44,1992). The routine can be downloaded at: visit the web site.   (inserted on 24/10/2012)

PhD and PostoDoctoral positions available: Environmental ChemOinformatic (ECO) Marie Curie Initial Training Network (ITN) is a collaborative action of 7 institutions from 5 EU countries (Germany, The Netherlands, Spain, Sweden, Italy). The primary objective of this ITN is to contribute to the education of environmental chemo-informaticians who will receive an advanced training in both environmental sciences and computational in silico methods. The fellows of the network are expected to apply their knowledge for the implementation of REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) in particular with respect to the replacement, refinement and reduction of animal tests by alternative (in silico and in vitro) methods.
ECO provides 11 positions (Early Stage Researchers in EU terminology) leading towards PhD and 1 postdoctoral position (Experienced Researcher in EU terminology, 1 year duration) starting before September 2010. The selection of fellows will be done on March 31st – April 1st.

MOLE db - Molecular Descriptors Data Base: The MOLE db - Molecular Descriptors Data Base is a free on-line database constituted of 1124 molecular descriptors calculated on 234773 molecules. This data base is intended as a research and teaching tool and basically allows the researcher to: a) search for a specific group of molecules and analyse the corresponding values of molecular descriptors b) save in an output file the values of a block of molecular descriptors calculated on a group of molecules. Explore the data base here.   (inserted on 10/03/2008)

New version 5.5 of DRAGON software: In DRAGON 5.5 two new blocks of molecular descriptors were added, leading to a total of 1560 (780x2) new descriptors. The new block 21 is comprised of 2D binary fingerprints, which define the presence (1) or absence (0) of specific atom pairs at different topological distances (from 1 to 10). The new block 22 is comprised of 2D frequency fingerprints, which differ from the binary fingerprints since the frequency of specific atom pairs at different topological distances (from 1 to 10) is calculated. The considered atom pairs are the combinations of C, N, O, S, P, F, Cl, Br, I, B, Si and X (where X represents any other atom, except hydrogen).   (inserted on 26/11/2007)
