The Trident Graphical User Interface. A single,
fully-integrated, and easy to use interface provides medicinal chemists
with tools for building (Organic and Substituent model kits) and importing
structures (common molecular file types), database query (access to
provided Spartan Molecular Database collection, the Cambridge Structural
Database <requires license>, and the Protein Databank), task
submission (a single calculations dialogue accesses all computational
and graphics requests), and visualization of results (Trident graphics,
property and similarity dialogues, spreadsheets, plots, and text output). |

 |
Model Kits: |
|
| |
Organic |
Accesses a builder consisting of organic elements and common bond
types (e.g., "sp3 carbon"), functional groups,
rings, and custom menus accessing provided libraries of common substructures
and the ability to add your own libraries. |
| |
|
|
| |
Substituent |
Provides tools for easily constructing libraries of substituted
systems by adding common functional groups or your own custom groups
at selected positions on a common molecular scaffold. |
| |
|
|
| |
Building |
Trident provides easy to use Menu or Icon driven modes for adding
fragments, deleting, making bonds, breaking bonds, inserting non-bonded
fragments or molecules. |

Graphical Displays: |
|
| |
|
|
| |
Molecule Display |
Trident includes several display styles for visualizing molecules:
wire, ball-and-wire, tube, ball-and-spoke, and space filling models. |
| |
|
|
| |
Hydrogen Bonds |
Optional display of hydrogen inter- and intra- molecular hydrogen
bonds are available. |
| |
|
|
| |
Biopolymers |
Secondary structures for Polypeptides and polynucleotides can be
optionally rendered with "ribbon" displays, lines, or beads.
Colors may be configured to emphasize strand, secondary structure,
or residue type. |
| |
|
|
| |
Chemical Function Descriptors |
Trident can graphically display chemical function descriptors (CFD's),
identifying hydrogen bond acceptors and donors, positive and negative
ionizable centers, aromatic rings, and hydrophobes. Users can vary
CFD definitions. |
