SYBYL Line Notation

SYBYL Line Notation (SLN) is a chemical line notation. Based on SMILES, it incorporates a complete syntax for specifying relative stereochemistry. SLN has a rich query syntax that allows for the specification of Markush queries. The syntax also supports the specification of combinatorial libraries of CD.

Example SLNs

Description SLN String
Benzene CH:CH:CH:CH:CH:CH:@1
Alanine NH2CH(CH3)C(=O)OH
Query showing R sidechain R1C:C:C:C:C:C:@1
Query for amide/sulfamide NHC=M1{M1:O,S}

Famous quotes containing the word line:

    “Expediency of literature, reason of literature, lawfulness of writing down a thought, is questioned; much is to say on both sides, and, while the fight waxes hot, thou, dearest scholar, stick to thy foolish task, add a line every hour, and between whiles add a line.”
    —Ralph Waldo Emerson (1803–1882)
