ACD/ChemSketch What's New

Version 2018.1

Enhanced Drawing Features

• Conveniently edit structures by replacing atoms with keyboard shortcuts

Element	C	B	F	S	N	Cl	Br	O	H	I
Keyboard	c	b	f	s	n	l	r	o	h	i

• Calculated properties are updated on-the-fly as structures are edited

• Select from a variety of pattern or color options when working with Markush structures

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 2017.1

  

  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
  

  

  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

• Version 2016.1

  General Capabilities

  • Generate Stereo Descriptors button provides single-click access to set R/S configurations for stereo centers
  
  • Stereo-bond type and location are automatically selected in the structure
  
  • Generate all possible structures for a given Markush representation
  
  • Improved analysis of stereo-bonds removes ambiguity from complex stereochemical arrangements
  • Ability to define mixed stereochemistry configurations (relative, racemic, and absolute) within the same structure
  
  • Ability to customize the display of oligomers and generic polymers
  

  Ease of Use Improvements

  • Addition of several standard abbreviations for common chemical groups; groups can be expanded to show the complete structure
  
  • Improved positioning of atom labels on the left side of structures
