Chemical Structure Drawing Software | What's New in ACD/ChemSketch

Version 2019

As of v2019 ACD/Spectrus is compiled in a 64-bit architecture allowing the software to take greater advantage of system resources.

General Improvements

Stereobond analysis has been improved to take bond direction into account when generating stereodescriptors

Generation of sterodescriptors now takes bond direction into account.

Copy/paste reactions to third-party applications as a complete reaction sequence (as opposed to a set of structures)
Choose scaling options when inserting OLE objects to Microsoft Office applications
General improvements in file import/export options including ChemDraw files, and preferences for exporting molfiles

File import/export options have been expanded to include ChemDraw files, and detting your default preferences for molfile export.

Many other improvements have also been made to the software. Contact us below to learn more and to discuss updating your software installation.

General Improvements

Improved support for post-transition metals (elements Mt to Og)

Data Import/Export

Improved support for ChemDraw *.cdx, Biovia *.sks, and ChemAxon Marvin Sketch *.mrv
Set your default for molfile export to V2000 or V3000

Version 2017
Biotools now available for creating sequences using one or three letter codes

Draw/Edit Peptide Sequences with ease using the New Biosequence Tools
- Add individual amino acids (both standard and non-standard) along with groups and linkers to the sequence with a single click while maintaining the chemical structure intelligence inherent within ChemSketch
- Structure preview is available for each molecule within the Biosequence Drawing tool
- Both standard one-letter or three-letter peptide sequence codes are available
- Easily switch between single, three letter notation and full structure of amino acids
- Added ability to assign amino acid NMR resonances from either the single or three letter notation for conveniences (refer to new NMR features in Spectrus Processor / NMR Workbook Suite)
Improvements and Additions to ChemSketch Add-ons
- Generate all possible stereoisomers for a structure with the new Stereoisomer Generator add-on
Addition of four new elements to the Periodic Table

Enhanced Drawing Features
- Addition of four new elements (nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og)) to the Periodic Table
- Custom color can be set on each level of Markush shadows
- Addition of Edit menu commands to the workspace right-click menu
Algorithm Updates
- InChI Tools now updated to version 1.05
- Generate InChI and SMILES notations for multiple components
Data Import/Export
- FASTA and HELM file formats are now supported for import/export
- Copy/paste sequences drawn in other programs (ChemDraw and Biovia Draw) directly into ChemSketch with the implementation of the new Biosequence Tools
