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.

SPRESImobile provides direct access to ChemReact, a subset of the SPRESI structure and reaction database, which contains more than 400,000 unique reaction types and the related references. SPRESImobile allows searching by name and structure queries, exact, substructure and All-in-one (Flex) search. There is a list of iOS applications on the mobile science page.

I’ve just added Brain Lab to the list of mobile science applications Brain Lab is a brain cell simulator, currently it offers

1. A passive integrate and fire model
2. A full Hodgkin-Huxley model with sodium and potassium channels
3. A Library to learn more about brain science

Brain Lab offers real scientific brain cell models that can be used by anyone, no matter if you are a student, a scientist, or someone who is just interested in brain science. To carry out your experiments, they have set up a Lab for you with all the necessary equipment. If you need to brush up your brain science knowledge or look up a specific technical term, you can go to your Library and read it up. 

The Open Drug Discovery Teams (ODDT) project is a mobile app primarily intended as a research topic aggregator of open science data integrated from various sources on the internet. It exists to facilitate interdisciplinary teamwork and to relieve the user from data overload. Initial research topics include areas of chemistry and adjacent molecule-oriented biomedical sciences, with an emphasis on those which are most amenable to open research at present. The ODDT project uses a free mobile app for iOS-based devices (iPhone, iPod and iPad) as the hub. The app has a Flipboard-inspired interface, and serverside infrastructure for hosting data and value added services. The project is open to participation from anyone, and much of the content is derived from public sources but is amenable to commercial data input and they are now looking for alpha testers. One of the key components is a back-end server that is in charge of monitoring the appearance of tweets with certain hash tags (#tuberculosis, #malaria, #hivaids, #huntingtons, #sanfilipposyndrome and #greenchemistry).

There is a screencast here to give you an idea of the functionality.

A chart & graph library for iOS and Mac OS X developers.

• Fully native Objective-C library for direct, easy use in any iOS XCode project.

Mobile hardware and software technology continues to evolve very rapidly and presents drug discovery scientists with new platforms for accessing data and performing data analysis. Smartphones and tablet computers can now be used to perform many of the operations previously addressed by laptops or desktop computers. Although the smaller screen sizes and requirements for touch-screen manipulation can present user-interface design challenges, especially with chemistry-related applications, these limitations are driving innovative solutions. In this early review of the topic, we collectively present our diverse experiences as software developer, chemistry database expert and naïve user, in terms of what mobile platforms could provide to the drug discovery chemist in the way of applications in the future as this disruptive technology takes off.
