Version 3.0 of the javascript chemical drawing package Xemistry Web Sketcher has been released.

This joins a list of javascript powered chemical drawing tools. It seems pretty fully featured but I have to confess I prefer a rather more minimalist interface with templates, elements available from menus. However drawing packages are very much a personal preference.

Elemental from Dotmatics a Chemistry Sketch Utility

Elemental is the Dotmatics chemistry sketch utility provided at no charge within many Dotmatics products. Now provided as a FREE app on the iTunes store.

There is a list of mobile science apps here.

The Mobile Molecular DataSheet (MMDS) has been updated. Two major usability enhancements:

(1) Additional tool banks on the left and right side of the sketcher provide simplified drawing tools that are more familiar to users of desktop chemical drawing software.

(2) A tooltip system provides tips, live demonstrations and links to documentation.

I was reminded that whilst scripting menu items was the traditional way of controlling ChemDraw the more recent releases allow control by scripting commands. This is a major advance since menus can change or be translated into other languages. I’ve thus updated the script.

I was asked if it would be possible to do the same thing for other drawing packages such as MarvinSketch?

The answer is yes but because MarvinSketch does not have applescript support we have to do it slightly differently. Rather than using scripting commands we script system events to evoke the “Paste” command.

Full details of the script are here

I’ve added two new applications from Metamolecular to the alphabetical listing.

ChemVector™ offers a modern solution to the chemical structure imaging problem. Features

• 100% JavaScript. No browser plugins are necessary.
• Runs with all commonly-used browsers on Windows, Linux, Mac, and iPad. This includes Internet Explorer 6-9 in addition to Firefox, Google Chrome, and Safari.
• Renders structures directly from individual molfiles on a server, or as inline content.
• Renders chemical structure content directly from ChemDraw™ binary files (.cdx).
• Declarative syntax replaces <img> tags with analogous <object> tags, making it easy for both developers and designers to work with the resulting markup.
• Non-blocking implementation makes it possible to render dozens of structures on a single page while maintaining UI responsiveness.
• Structures can be magnified pre- or post-rendering with no pixelation.

ChemCore is the chemiformatics foundation of all of the Metamolecular products and services. Written in Java and cross-compilable to a number of target runtimes and platforms, ChemCore is both fast and flexible.

Features

• Fast subgraph matching
• Powerful graph query capabilities
• Flexible, efficient graph traversals
• Fast file input/output
• A complete system of atomic weights and elemental properties
• Sensible handling of implicit hydrogens
• Molecule validation and correctness-checking
• Molecule transformations, including canonicalization and salt-stripping
• 100% Java cross-compilable to JavaScript and other target runtimes and platforms
• Extensively tested and documented

MolPrime is a chemical structure drawing tool based on the unique sketcher from the Mobile Molecular DataSheet

Added to the Mobile Science Page.

There is also a comparison of six chemical drawing packages here

I’ve corrected the broken links in the Protein Ribbon Models of Proteins tutorial using the ChemDoodle Web Components.

There are more tutorials here and a selection of software reviews here.

JSDraw™ is a chemical structure editor/viewer built in 100% Javascript, running on all platforms, including Windows, Mac, Linux, iPad/iPhone, Android tablets/phones and Chromebooks. JSDraw 1.3.0 release includes following improvements and changes:

• The js file is renamed to Scilligence.JSDraw.js
• Speeded up JSDraw on IE 6/7/8 by adopting Silverlight
• Added fragment-selecting tool ( http://www.scilligence.com/web/fragment-selecting-tool-in-jsdraw-1210.aspx )
• Improved drawing performance
• Being able to expand Amino Acid using right click menu ( http://www.scilligence.com/web/bio-features-expanding-amino-acid.aspx )
• Bug: atom labels overlaps bonds
• Added Bracket object to support polymers ( http://www.scilligence.com/web/polymer-features-comes-to-jsdraw-1210.aspx )
• Added Lasso selecting tool ( http://www.scilligence.com/web/jsdraw-lasso-selecting-tool.aspx )
• Widely supporting SGroup ( http://www.scilligence.com/web/sgroup-in-jsdraw.aspx )
• Being able to Set object colors

CLiDE is a chemistry intelligent equivalent of Optical Character Recognition (OCR) software. Just as an OCR can recognize characters from a scanned images of printed text, CLiDE can recognize structures, reactions and text from scanned images of printed chemistry literature. The software saves users hours of redrawing structures from printed material, as it transforms the 'images' into a 'real structures' that can then be input into databases.

The new and improved features of the latest release include:

• support for Windows, MAC and Linux operating systems
• improved structure recognition capability
• improved error reporting
• improved processing of document pages which contain tables, underlined text and page separator lines that touch a few letters
• extended input format support with Word (DOC and DOCX) and HTML
• extended export format support with CML and MRV formats
• integrated support for ChemAxon's Marvin Sketch, Accelrys'Draw and ChemDraw editors

ChemBioDraw 12.0.2
CambridgeSoft have released an update for the Mac version of ChemBioDraw

• JSDraw 1.1.0 is released with a new spreadsheet display.
