The Arylpyrrole Series

The initial two leads have the general structure:

GSK Tres Cantos Arylpyrrole Generic Structure
GSK Tres Cantos Arylpyrrole Generic Structure

These compounds are currently under study by the Todd lab at the University of Sydney and the Medicines for Malaria Venture, Geneva. As an open source project, anyone may participate:
Coordination/Discussion site
Electronic Lab Notebooks
Compounds are commercially-available
Series was listed as one of the most promising leads from TCAMS set (though lacking aryl F)

A number of these compounds and intermediates are available for biological testing from Todd group by request.
