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:
“The line it is drawn
The curse it is cast
The slow one now
Will later be fast
As the present now
Will later be past
The order is
Rapidly fadin’.
And the first one now
Will later be last
For the times they are a-changin’.”
—Bob Dylan [Robert Allen Zimmerman] (b. 1941)
