By applying a semi-empirical quantum chemistry program MOPAC, ChemoPy can also compute a large number of 3D molecular descriptors conveniently. Recent advances in QSAR and their applications in predicting the activities of chemical molecules, peptides and proteins for drug design. Cheminformatics software, calculation of molecular properties, prediction of bioactivity, virtual screening, molecular databases. - Molecular Descriptors - Calculate properties.

Molinspiration offers supporting molecule manipulation and processing, including SMILES and SDfile conversion, normalization of molecules, generation of tautomers, molecule fragmentation, calculation of various molecular properties needed in QSAR, molecular modelling and drug design, high quality molecule depiction, molecular database tools supporting substructure and similarity searches. Our products support also fragment-based virtual screening, bioactivity prediction and data visualization.

Molinspiration tools are written in Java, therefore can be used practically on any computer platform.

Molecular descriptors are experimentally-measured or theoretically-derived properties of a molecule. More specifically, they are quantitative representations of physical, chemical or topological characteristics of molecules that summarize our knowledge and understanding of molecular structure and activity from different aspects. Molecular fingerprints are property profiles of a molecule, usually in forms of bit or count vectors with the vector elements indicating the existence or the frequencies of certain properties, respectively. Download Game Yakyuken Special Psx Rom there. Both molecular descriptors and fingerprints play a fundamental role in QSAR/SAR analysis, virtual molecule screening, similarity-based compound search, target molecule ranking, drug ADME/T prediction and the other drug discovery processes.
