ChemDraw Changelog

What's new in ChemDraw 16.0.0.82

Dec 22, 2016
  • Cocoa framework support:
  • ChemDraw 16.0 comes with Cocoa framework support, thus providing better compatibility and enhanced look and feel in Chemdraw UI.
  • Unicode Support:
  • ChemDraw 16.0 adds support for unicode on the Mac. It allows characters and symbols from most of the world's writing systems to be represented in a consistent way, independent of fonts or system settings. The full gamut of unicode characters is supported, this includes a large number of scripts, symbols, emojis and images. The system "Emojis and Symbols" panel can be used to add characters and symbols that are not on the user's keyboard. Text can be pasted from any source without loss. Mac OS X will substitute fonts automatically to ensure that characters can be rendered.
  • Autosave and Autorecovery:
  • Autosave is now available on a system level. By default, documents will be saved automatically. The user will not be asked to save changes. In addition,"Save As..." is not available by default. See Auto Save and Versioning
  • Recent Documents:
  • Click File > Open Recent to view your most recent documents. This has moved from the bottom of the File menu.
  • File and Edit Menus:
  • The File menu has some changes to support Auto Save and Versioning, moving documents etc, see "Auto Save and Versioning" and Documents".
  • The Edit menu has additional items for handling text - Spelling, Substitutions, Transformations, Speech, Start Dictation and Emoji & Symbols
  • Browse Versions:
  • A Browse Versions feature allows users to revert their document to a previous version. See Browsing Versions
  • Enhanced Retrosynthesis Tool:
  • Using the Enhanced Retrosynthesis tool, you can now analyze how a molecule might have been constructed. For details, see "Enhanced Retrosynthesis tool".
  • ChemDraw Cloud:
  • ChemDraw is now available without any installation in ChemDraw Cloud. ChemDraw Desktop and ChemDraw Cloud can share files via upload and download. For details, see Understanding ChemDraw Cloud
  • Attach Data feature enhancement:
  • You can now specify a single character tag while attaching data to an object. These tags will be displayed along with objects. For details, see "Attached Data".
  • Stereoflag Configuration Options:
  • You can choose to display one general stereoflag label for the molecule (instead of stereoflag labels in individual stereo-centers) when opening MDL format files. For details see, Configuration options for stereoflag.
  • You can now save the Enhanced Stereochemistry settings when saving to the SKC format. For details, see Configuration options for stereoflag.

New in ChemDraw 15.0.0.106 (Jun 10, 2015)

  • Windows 8.1, Microsoft Office 2013, Mac OS X 10.9.x and Mac OS X 10.10.x:
  • ChemDraw strives to be a vital and preferred tool for illustrating chemical and biological concepts. Compatibility with the latest operating systems and tools is an essential part of that. Having the ChemDraw Active-X control functional with the latest browsers on both Windows and Mac platforms is part of this process, as well.
  • ChemDraw to SciFinder Interface:
  • Send ChemDraw structure and reaction queries directly to SciFinder to find useful information relevant to your compound/reaction.
  • Biopolymer Builder Enhancements:
  • Single and multi letter amino acids - Lets you create single letter amino acids and nucleotides either by entering the corresponding IUPAC code, or by using the Biopolymer toolbar. The Biopolymer Editor lets you create three letter, or non-standard amino acids, by entering the residue name.
  • Toggle Amino Acid Style AA1AA3 command - Lets you change the amino acid representation from single to multi-letter, and vice versa.
  • L- and D- amino acids - Lets you create standard L- or D-amino acids by entering the relevant IUPAC code.
  • Toggle L- and D-amino acids -The ‘Toggle Amino Acid Stereo LD’ command lets you change the stereochemistry of amino acids from L to D and vice versa.
  • Protecting groups - Lets you add protecting groups such as Trt and Fmoc to amino acids containing additional NH2 or OH groups (Arg, Aad). You can also expand and contract the protected residues.
  • Cyclic and branched peptides - Lets you create cyclic peptides by bonding together the terminal residues in a peptide sequence. A looped bond indicates that the peptide is cyclic. You can create branched peptides using the sequence builder and bond tools.
  • Lactam bridges - Lets you form lactam bridges between residues with available amino and carboxylic acid leaving groups, such as Lys-Asp and Lys-Glu.
  • Merging sequences - Lets you merge multiple sequences into one sequence by bonding together their terminal residues.
  • Hybrid biopolymers - Lets you create hybrid (also called 'chimeric') biopolymers containing peptide, nucleotide, and linker residues, using the Biopolymer toolbar.
  • Pasting sequences - Lets you paste sequences in the FASTA format. You can also copy a text string describing a biopolymer as a series of single or multi letter residues, with valid separators (space, tab, dash), and paste it as a sequence. The text string can be generated within or outside of ChemDraw. See Pasting Sequences.
  • Displaying expanded residues - Expanded residues can appear in either linear mode or zigzag mode.
  • Expanding and contracting labels - Lets you expand the entire sequence, or any part of it. The sequence is automatically cleaned following expansion.
  • When you contract a sequence, the Clean Up Biopolymer command cleans and re-arranges the sequence, so that the residues are aligned and wrapped.
  • Numbering residues - Lets you display residue numbers above any residue.
  • Hide/Show termini and bonds - Lets you hide bonds and termini without affecting the underlying chemistry.
  • Nickname Enhancements:
  • In ChemDraw 15.0, many new residues, for example, non-standard amino acids, non-standard nucleotides, linkers have been added to the nickname library. Defining nicknames is much easier and more flexible now.For more information on nicknames, see Defining Nicknames.
  • Struct>Name Enhancements:
  • Struct>Name in ChemDraw 15.0 is enhanced to support many homopolymers, copolymers, and alternating polymers, and stoichiometry specified as bracket properties, including fractional stoichiometry.
  • Electron Pushing:
  • ChemDraw 15.0 introduces the Electron Pushing tool for illustrating electron transfer.
  • Gel Electrophoresis Tool:
  • Gel electrophoresis separates molecules using an electric field applied to a gel matrix. The gel electrophoresis tool in ChemDraw 15.0 works much like the TLC tool and lets you easily draw and mark bands based on weight or distance.
  • TLC Plate Enhancements:
  • Lets you copy and drag spots between lanes.
  • Polymer Bead Enhancements:
  • Lets you re-size polymer beads. For more information on polymer beads and other attachment points, see Attachment Points.
  • New Toolbars:
  • ChemDraw 15.0 introduces several new toolbars, including, Structure, Curves, Windows, and Biopolymer toolbars. You access these toolbars from the View menu.
  • Color by Element:
  • Lets you color atom labels using colors associated with their atomic symbols, as shown in the example below.
  • New Property Predictions:
  • Incorporates new calculations from Molecular Networks for predicting pKa, LogS and LogP. See Property Predictions in ChemDraw.
  • JPEG/ JPG file export:
  • Lets you export files of type JPEG.
  • Copy As/Paste Special CDXML, MOL and MOL V3000 files as text:
  • Lets you save CDXML, MOL, and MOL V3000 files to the clipboard as text and then paste in other applications as text.
  • Copy Structure to MS Word from ChemDraw/Excel:
  • Lets you copy structures from ChemDraw/Excel worksheets to Microsoft Word through a setting in the General Preferences dialog.
