As a member of the wwPDB, the RCSB PDB curates and annotates PDB data according to agreed upon standards. The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists Unlike chemical structure searching, chemical similarity searching looks for chemical structures that are related to a query molecule rather than an exact match. In similarity searching, the scientist can set just how similar a chemical structure must be to the query before it is determined to be a hit. First, the query molecule is broken down into all its component fragments. As illustrated. ChemExper is a company joining together the areas of chemistry, computer science and telecommunication.

New in PATENTSCOPE: Chemical Sub-Structure Searc

By integrating chemical search from ChemAxon and text mining from Linguamatics, I2E users can identify chemical structures and understand their role within documents such as patents, scientific articles, and internal documents. Applications include scientific research, intellectual property search, and commercial intelligence We have developed two types of chemical structure search servers; one is the similarity search server and another is the subgraph search, which is much faster than the former one. Both servers can provide the opportunity to investigate the detailed chemical features, including chirality and other physicochemical properties. A current limitation is the handling of R-group representation.

Chemical Structure Search Search similar compound structures. SIMCOMP: maximal common subgraph search -- a portion of the query compound is optimally matched to a portion of the database compound SUBCOMP: isomorphic subgraph search -- the query compound is fully matched to a portion of the database compound (substructure match) or a portion of the query compound is fully matched to the. The identification of low-energy conformers for a given molecule is a fundamental problem in computational chemistry and cheminformatics. We assess here a conformer search that employs a genetic algorithm for sampling the low-energy segment of the conformation space of molecules. The algorithm is designed to work with first-principles methods, facilitated by the incorporation of local. The chemical structure similarity search differs from the chemical substructure search in that the former requires assessment of the properties of each compound and thus no filter can be applied for skipping structures before they are assessed to accelerate the computation. The latter can be accelerated by pre-screening compounds and omitting those that miss one (or more) specified fragments. Listed below is a group of topics of interest to the chemical community. Each category includes documents relevant to the key words listed and represents a specialized grouping of documents relating to chemicals. We believe these categories will be of interest to scientists, health-professionals, chemists, and professionals in the pharmaceutical industry
