What’s new in Marvin?

  • Structure representation

  • Better quality graphics

  • Improved usability

  • New GUI design

  • Plug-ins

  • File IO

  • Future plans and discussion

Structure representation

Structure representation

  • Improvements in Markush compound drawing (alpha)

    • Position variation

    • Repeating unit with repetition ranges

Structure representation1

Structure representation

  • Coordination compounds (alpha)

    • New bond type: coordinate bond

      • Between atom – atom:

      • Between atom – group of atoms:

    • Connection to a group of atoms with multicenter attachment point

Structure representation3

Structure representation

  • Polymer drawing (alpha)

    • Source and structure-based representation of polymer types: SRU, repeating unit with repetition ranges, anypolymer, copolymer, crosslink, graft, mer, modification, monomer

Structure representation4

Structure representation

  • Drawing of ordered and unordered mixtures (release 4.1.2)

Structure representation5

Structure representation

  • Multistep reaction drawing (alpha)

    • Reaction scheme with any number and layout of graphical reaction arrows

Better quality graphics

Better quality graphics

  • Left and right abbreviations for abbreviated groups (release 4.1)

Better quality graphics1

Better quality graphics

  • Improved 2D cleaning (alpha)

    • Nice cleaning of big rings (built up from hexagons)

    • Template based



Better quality graphics2

Better quality graphics



Better quality graphics3

Better quality graphics

  • New graphical objects

    • Graphical arrow in reaction (release 4.1.8)

    • Graphical brackets (alpha)

Improved usability

Improved usability

  • Status bar with 2D/3D drawing mode selection and modified status (alpha)

  • Chain drawing mode button (alpha)

Improved usability1

Improved usability

  • Insertable OLE component into MSOffice documents (alpha)

New gui design

New GUI design

  • Customizable menus and toolbar (alpha)

  • Customizable shortcut keys (alpha)

    Three ways of customization (alpha) :

    • Interactive

    • Configuration file

    • API

New gui design1

New GUI design

  • Toolbar and menubar icons

  • Cross-platform “Java Look” (JGoodies)

  • Improved User Interface design and usability “Java Feel” (coming soon)

New gui design2

New GUI design

Sample default layout demonstrating graphics design

New gui design3

New GUI design


New gui design4

New GUI design

Sample customized layout

Appearing actions are customized

Toolbar icon sizes are customized

Menu is reorganized by creating a new custom menu

Plug ins


  • Tautomerization Calculator Plugin:

    • Generation of the major (dominant) tautomeric forms based on predicted pKa values. (release 4.1)

    • Generation of the canonic tautomeric form based on predicted pKa and an empirical rule system.  Filtering of tautomer couples. (release 4.1.9)

    • Prediction of the tautomer distribution. (release 4.1.9)

Plug ins1


  • The length of the tautomerization path can optionally be adjusted. (release 4.1.9)

  • Takes into account the major tautomeric form in the pKa, logP, and the logD calculations. (release 4.2)

  • Markush enumeration Calculator Plugin (alpha)

  • Structure to name Calculator Plugin (release 4.1.7)

    • Traditional or IUPAC name

  • Plug ins2


    • Name generation is free when used from Marvin GUI.

    • Real-time updated name display in MarvinSketch (alpha)

    File io

    File IO

    • Saving of specific Marvin settings, stored in mrv with structure (alpha)

    • PDB import improvements, for example multi-model proteins (release 4.1.2)

    Future plans and discussion

    Future plans and discussion

    • Basic structural IO of CDX (ChemDraw) format

    • Align & distribute for molecules in MarvinSketch

    • Load Templates from specified directories

      • Spreadsheet-like table where different columns store different types of data

    Future plans and discussion1

    Future plans and discussion

    • Name to structure

    • New skins for Marvin to help chemists who are used to other programs like ChemDraw and Isis/Draw.
