All general (non-disease specific) open source research projects currently in process should be created as child pages to this page. See the "add child" link at the bottom to create your own project page.
Great news! The Synaptic Leap will roll out a new research community for schistosomiasis very soon. This will require evolving our pilot site from a single research community to a site that supports multiple research communities. We will also create a TSL non-research oriented community for general open-source biomedical research discussion and tools and we will evolve this to become our only site to communicate with you.
We have a prototype of this new infrastructure on our development site. We are getting feedback from our advisors and research community leaders and are improving the general site usability too. As change ideas and content firms up, we will slowly roll out the changes.
I will do my best to keep you informed on these upcoming changes by evolving the information on this page. This list will evolve in terms of what's to be done as well as what is already done. Check back periodically to see where we are in the process. Oh yes, and feel free to login and add comments to give us feedback on these changes.
Thanks in advance for your patience and your input.
Collaborative Drug Discovery's web-database enables scientists to archive, mine, and collaborate to more effectively develop new drug candidates for commercial and humanitarian markets.
OpenWetWare is a great site for scientific wikis. You can create wiki spaces to suit your needs. We hope that all wet lab scientists in our community reference and contribute to that wiki as they work on their open research projects within TSL.
Connotea and CiteULike are social bookmarking sites specializing in academic content. They also produce RSS feeds!
UsefulChem Project is a blog focused on chemistry.
I encourage you to add comments below to list your favorite collaborative scientific website or tool.
Marc's collaborative genomic modules for malaria have inspired me. Given the power of open source solutions such as Drupal, any community savvy software person can deploy a collaborative community. The secret sauce is allowing scientists to help extend the collaboration modules to meet new and yet-to-be imagined needs. My goal is to provide a push-button software development environment for other programming savvy scientists. We need to provide secure access to the development tools, complete with development standards and guidelines, version control, quality checks and migration to the main site procedures. These same tools will enable us to put any volunteer to work in evolving our platform.
This is still at the idea stage so far. Once I write down the requirements, I will attach them to this project page.
I need at least one software programmer with the following skills:

There has been an interesting conversation over at Friendfeed about the value of centralised vs. decentralised synthetic procedures for chemistry. i.e. should we try to create a store of chemical reactions, or ought we to be expecting decent search tools to be able to find these for us, wherever they are. From my perspective, both have value. Naturally what we need are tools that understand descriptions of reactions that are semantic (plain English), and which can understand various forms of data that go along with compounds.
So I thought we'd give it a try with a random sample procedure, the conversion of tetrahydroisoquinoline to its Boc-protected form. Below is a simple procedure for this, written as if we were submitting this to some web archive of procedures. Also attached are some data for the product - .dx files for JSpecView-ing the proton NMR spectrum, plus a pdf of the same. There are gifs of the reaction itself, plus one of a TLC of the reaction. I'll shortly upload some other things below. I have no idea what any search tool will make of such a mish-mash.
Antony Williams can hopefully unleash ChemSpider, and extract information from this? I also want to try to upload the same data directly to the relevant page on Chemspider, to see if I can just deposit it there. Which of these two approaches is preferable?

2-Boc-1,2,3,4-tetrahydroisoquinoline
Submitted by Althea Tsang and Matthew H. Todd, School of Chemistry, University of Sydney, NSW 2006, Australia. Checked by Victor Sun, Lakshmi Raj Baratha, Soo-Jean Park, same address.
Preparation of Boc-THIQ
To 1,2,3,4-tetrahydroisoquinoline (2.00 g, 15.0 mmol) in dichloromethane (10 mL), triethylamine (3.1 mL, 22.6 mmol, 1.5 eq) and 4-dimethylaminopyridine (0.180 g, 1.5 mmol, 0.1 eq) were added. Di-tert-butyl dicarbonate (4.92 g, 22.6 mmol, 1.5 eq) was added and the reaction mixture stirred at rt for 24 h. The reaction mixture was diluted with dichloromethane (50 mL), washed with water (50 mL) and the organic portions extracted, dried (MgSO4) and concentratedin vacuoto give a bright yellow oil, which was purified by flash column chromatography (3:1 ethyl acetate:hexane) to give the product as a bright yellow oil (3.49 g, 99%)
TLC (hexane:ethyl acetate, 5:1) after 3.5 hours indicated only product and baseline spots. TLC after 23 h indicated slight appearance of second spot at Rf = 0.38.
1H NMR (CDCl3): δ 1.49 (9H, s, H9), 2.83 (2H, dd,J5.8, 5.8, H4), 3.64 (2H, dd,J5.8, 5.8, H3), 4.57 (2H, s, H1), 7.05 “ 7.35 (4H, m). IR (CHCl3) νmax/cm-11682, 1419, 1173. m/z (ESI) 132.1 (100%).

Addenda:
1) Original procedure used 1 N HCl wash as well as sat. NaHCO3 wash. No column chromatography.
2) Dilute NaHCO3 wash used in above procedure, working equally well.
3) Column in 1:1 hexane:ethyl acetate works equally well.
