3. SMILES - A Simplified Chemical Language SMILES (Simplified Molecular Input Line Entry System) is aline notation(a typographical method using printable characters) for entering and representing molecules and
Generative machine learning models have attracted intense interest for their ability to sample novel molecules with desired chemical or biological properties. Among these, language models trained on SMILES (Simplified Molecular-Input Line-Entry System) representations have been subject to the most extensive...
因此,毒理数据库与QSAR软件允许用户以计算机的方式表示分子结构的SMILES方式,来与数据库/软件进行交互。SMILES(Simplified Molecular Input Line Entry System)是一种计算机交互语言,是专门设计的化学符号语言,它对于使用者来说很容易获得,且又足够灵活,是化学符号的解释和生成独立于使用的特定计算机系统(如QSAR软件、VEGA...
The original specification of SMILES was provided by Daylight Chemical Information Systems in "SMILES - A Simplified Chemical Language" athttps://www.daylight.com/dayhtml/doc/theory/theory.smiles.html. Currently, a more formal specification is provided by Craig A. James as "OpenSMILES specification...

Encoding molecular compounds in both human- and computer-readable formats is a necessary step in CADD. A convenient encoding is SMILES, or simplified molecular-input line-entry system [15]. As the name suggests, SMILES is a linear notation of a molecule based on atom and bond enumeration, as...
This stems from the fact that chemical compounds can be effectively represented through chemical languages such as the Simplified Molecular Input Line Entry System (SMILES)9 or SELFES,10 which mirror the structure of natural language. Consequently, a plethora of scholarly works on molecular design ...
Disconnected compounds are written as individual structures separated by a period. Isomeric specification Configuration around double bonds is specified by "directional bonds": / and \. Configuration around tetrahedral centers may be indicated by a simplified chiral specification (parity) @ or @@. ...
This chapter provides introductions and tutorial examples on SMILES (Simplified Molecular-Input Line-Entry System). Topics include SMILES representations for atoms, bonds, rings, disconnected structures, charges, directional bonds, isotopes, chiral cente
In the case of in silico analysis, several digital file formats are defined to enable computers to read chemical compounds. Among these formats, MOL, SDF, Fingerprints, and SMILES (Simplified Molecular Input Line Entry System) are the most widely used. MOL is a file format that represents a...
