Symyx Draw has the same look-and-feel as ISIS/Draw, but bringsadditional speed and efficiency to chemical structure drawing:

• Continuously draw bonds, pull out rings, and add atoms usingall-purpose drawing tool

• Drag-and-drop commonly-used structures and chemical abbreviationsonto the toolbar for reuse

• Right-click for atom, bond, fragment properties, and query options

• Quickly retrace steps using Multiple Undo/Redo

• Easily create structures with Rgroups for queries or enumerations

• Annotate reaction schemes with text, color, and a variety ofarrow styles

• Easily create publication-quality structures

Easy to integrate and configure

As an enterprise software application, Symyx Draw offers flexibleintegration with custom Java® and .NET applications as well asintegration with Symyx Isentris® and ISIS applications. Use XMLto configure the chemical drawing look-and-feel according to therganization’s needs.

• Create custom add-ins to enhance the scientist’s drawing experience

• Integrate with existing desktop applications

• Leverage Web applications for query and browsing

Figure 1: Drawing a synthesis suitable for high-quality printing is simple with Symyx Draw. The product name displayed below the structure was gnerated automatically using the included structure-to-name generator.

For scientists—Quick and efficient structure andquery drawing

• Structure converter converts structure-to-IUPAC name and IUPACname-to-structure; structure-to-canonical SMILES and SMILES-tostructure;structure-to-InChI name and InChI name-to-structure; andstructure-to-InChI key

• Create and edit ISIS-compatible sketches, edit legacy sketches withimproved cleaning of sketches

• Ease the transition with familiar ISIS/Draw-like chemical drawingtools and behaviors

• Create and edit polymers, formulations, and mixtures (Sgroups)

• Create and edit Rgroup (Markush) queries including built-in Rgroupquery logic

• Create and edit 3D queries, all 3D query features supportedincluding 3D rotate

• Customize symbols including composite symbols

• Choose from large library of protecting group templates

• Take advantage of improved chemical recognition of tetrahedral andgeometric stereogenic centers made possible by Symyx NEMAalgorithm

For biochemists—Draw, register, search, and report onchemically modified peptide or nucleotide sequences

• Create 1- and 3-letter peptide, DNA, or RNA sequences with aSequence tool

• Use the same tool to draw crossing bonds, disulfide bridges andattach side-chain protecting groups

• Convert text from the clipboard, FASTA, Swiss-Prot, PDB, and EMBLfiles into chemically significant sequences

• Expand residues in a sequence to full structure to illustrate chemicalmodifications

Figure 2: Easily create, register, search, and present 1- and 3-letter peptides,DNA, and RNA. Modify sequences to include unnatural residues. Use templates to add protecting groups.

Figure 3: All polymer, mixture, and formulation Sgroup features are supported. Inthis example, a combination of Generic and data  goups is used to represent aMarkush structure.

Figure 4: Polymers, mixtures, and formulations. An example of a complexmixture containing a Markush structure and a source-based representation ofpolyethylene terephthalate (PET) are depicted.
