The simplified molecular-input line-entry system (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three … See more The original SMILES specification was initiated by David Weininger at the USEPA Mid-Continent Ecology Division Laboratory in Duluth in the 1980s. Acknowledged for their parts in the early development were "Gilman Veith and … See more The term SMILES refers to a line notation for encoding molecular structures and specific instances should strictly be called SMILES strings. However, the term SMILES is also … See more From the view point of a formal language theory, SMILES is a word. A SMILES is parsable with a context-free parser. The use of this representation has been in the prediction of biochemical properties (incl. toxicity and biodegradability) based on the main principle of … See more SMARTS is a line notation for specification of substructural patterns in molecules. While it uses many of the same symbols as SMILES, it also allows specification of wildcard atoms and bonds, which can be used to define substructural queries for chemical database searching. … See more In terms of a graph-based computational procedure, SMILES is a string obtained by printing the symbol nodes encountered in a depth-first tree traversal of a chemical graph. … See more Atoms Atoms are represented by the standard abbreviation of the chemical elements, in square brackets, such as [Au] for gold. Brackets may be omitted in the common case of atoms which: 1. are … See more SMILES can be converted back to two-dimensional representations using structure diagram generation (SDG) algorithms. This conversion is not always unambiguous. Conversion to three-dimensional representation is achieved by energy-minimization … See more WebPubChem Explore Chemistry Quickly find chemical information from authoritative sources Try covid-19 aspirin EGFR C9H8O4 57-27-2 C1=CC=C (C=C1)C=O InChI=1S/C3H6O/c1-3 (2)4/h1-2H3 Use Entrez Compounds Substances BioAssays Draw Structure Upload ID List Browse Data Periodic Table 115M Compounds 304M Substances 304M Bioactivities 35M …
