For those of you who use the safari browser as part of your normal work, Matt Swain has written a plugin that you might find useful. You simply highlight words within a page, right-click, and then a box pops up with the option to search chembl for that chemical structure (using the selected text as the query). Matt also wrote similar plugins for ChemSpider, PubChem and OPSIN. These, and more, are available here. Thanks Matt!
