In this article, we will show you how to download ISIS/Draw for Windows and Mac computers, and how to use its features to draw chemical structures and reactions. We will also compare it with other popular chemical drawing programs, such as ChemDraw and BIOVIA Draw.


How to Download ISIS/Draw for Windows and Mac




Downloading ISIS/Draw for Windows and Mac is free and simple. You can download it from the MDL web site (https://www.mdl.com/products/isis/isis_draw/index.jsp). You will need to register with your email address and create a password to access the download page. Once you have downloaded the installer file, you can run it and follow the instructions to install ISIS/Draw on your computer.


The latest version of ISIS/Draw is 2.5, which was released in 2008. The program is no longer supported by the developer, so you might encounter some compatibility issues with newer operating systems or devices. However, many users have reported that ISIS/Draw still works well on Windows 10 and Mac OS X.


How to Use ISIS/Draw to Draw Chemical Structures and Reactions




ISIS/Draw has a user-friendly interface that allows you to draw chemical structures and reactions using various tools and templates. You can access the main menu bar, the toolbar, the status bar, and the drawing area from the main window. You can also open multiple windows to work on different projects at the same time.


To draw a chemical structure, you can use the Atom Tool to select an element from the periodic table and place it on the drawing area. You can also use the Bond Tool to draw single, double, triple, or aromatic bonds between atoms. You can adjust the bond length, angle, or stereochemistry using the mouse or keyboard commands. You can also use the Template Tool to insert common functional groups or rings into your structure.


To draw a chemical reaction, you can use the Reaction Tool to draw arrows between reactants and products. You can also add reaction conditions or catalysts above or below the arrows. You can use the Group Tool to group or ungroup atoms or bonds into fragments or components. You can also use the Clean Up Tool to automatically arrange your structure or reaction in a more aesthetic way.


To draw a biological sequence, you can use the Sequence Tool to type in the amino acid abbreviations or nucleotide bases to build a peptide or DNA/RNA structure. You can also click on the appropriate residues in the Residue List to insert them into your sequence. You can orient your sequence using the mouse or keyboard commands. You can also use the Sequence Options dialog box to change the display mode, font size, or color of your sequence.


How to Compare ISIS/Draw with Other Chemical Drawing Programs




ISIS/Draw is one of the most popular chemical drawing programs among scientists and educators. It has many advantages over other programs, such as:


  • It is free and easy to download and install.



  • It has a simple and intuitive interface that allows you to draw complex structures and reactions quickly and accurately.



  • It has flexible tools that allow you to customize your drawings according to your preferences and needs.



  • It has unique capabilities for managing complex biological entities, such as peptides, oligonucleotides, and oligosaccharides.



  • It supports various file formats, such as MDL Molfile, MDL RXNfile, SMILES, InChI, ChemDraw CDX, etc.



However, ISIS/Draw also has some disadvantages over other programs


Some of the other popular chemical drawing programs are ChemDraw and BIOVIA Draw. ChemDraw is a program developed by PerkinElmer that is widely used by chemists and biologists for drawing and publishing chemical structures and reactions. BIOVIA Draw is a program developed by Dassault Systems that is based on ISIS/Draw but has more advanced features and capabilities.


Advantages and Disadvantages of ChemDraw




ChemDraw has some advantages over ISIS/Draw, such as:


  • It is more updated and supported by the developer, so it works better on newer operating systems and devices.



  • It has more features and tools for drawing and editing chemical structures and reactions, such as stereochemistry, atom numbering, reaction mapping, etc.



  • It has more integration options with other software and databases, such as ChemOffice, SciFinder, Reaxys, etc.



  • It has more options for exporting and sharing your drawings, such as PDF, PNG, SVG, etc.



However, ChemDraw also has some disadvantages over ISIS/Draw, such as:


  • It is not free and requires a license or subscription to use.



  • It has a more complex and cluttered interface that might be overwhelming for beginners or casual users.



  • It has less capabilities for managing complex biological entities, such as peptides, oligonucleotides, and oligosaccharides.



Advantages and Disadvantages of BIOVIA Draw




BIOVIA Draw has some advantages over ISIS/Draw, such as:


  • It is based on ISIS/Draw but has more updated and improved features and capabilities.



  • It has more options for drawing and editing complex molecules, chemical reactions and biological sequences.



  • It has more capabilities for managing complex biological entities, such as peptides, oligonucleotides, and oligosaccharides.



  • It supports various file formats, such as MDL Molfile, MDL RXNfile, SMILES, InChI, ChemDraw CDX, etc.



However, BIOVIA Draw also has some disadvantages over ISIS/Draw, such as:


  • It is not free and requires a license or subscription to use.



  • It is not compatible with some older operating systems or devices.



  • It has less integration options with other software and databases than ChemDraw.
