PubChem Plugin

This is a plugin for DokuWiki that creates the link or retrieve chemical structure for the compound identified by CID (Compound ID).


COMMAND: link, small, large, clear_cache, searchbox


command function
smallDisplay a small image of chemical structure
largeDisplay a large image of chemical structure
summaryXmlDisplay a summary XML from NCBI Structure database
IUPACDisplay an IUPAC name of a compound
formulaDisplay a molecular formula of a compound
searchBoxDisplay a search box of PubChem
clearClear all PubChem cache files
remove_dirClear and remove cache directory


A syntax {{pubchem>link:6248}} creates a link like this.



{{pubchem>large:6248}} retrieves a large image of chemical structure.
{{pubchem>small:6248}} retrieves a small image of chemical structure.

{{pubchem>summaryXML:6248}} displays a summary XML from NCBI.


{{pubchem>formula:6248}} displays a chemical formula of compound.


{{pubchem>IUPAC:6248}} displays an IUPAC name of compound.

Clearing cache images

You can clear all image files by {{pubchem>clear_cache}}. {{pubchem>remove_dir}} will clear all files and pubchem directory.


Recent dokuwiki has Extension manager in Admin tools. It can download and install the plugin automatically.

In very old dokuwiki

  1. Install bio plugin and cache plugin if not installed.
  2. Download and extract (6 KB).
  3. Upload the folder your DokuWiki at /lib/plugins/

This plugin automatically creates 'pubchem' namespace and caches images of chemical structure there.
