A little while ago I mentioned The Community for Open Antimicrobial Drug Discovery effort to provide free compound screening against a variety of infective agents. I now have a few more details of what you might be able to access for a 1mg sample.
Test against key ESKAPE pathogens, E. coli,
K. pneumoniae, A. baumannii, P. aeruginosa,
S. aureus (MRSA), as well as the fungi C. neoformans and C. albicans, at a single concentration.
Hit Confirmation:- Confirm activity with minimum inhibitory concentration and counterscreen for cytotoxicity and membrane interaction.
Hit Validation:- Test the positive hit against a broader panel of microbes and evaluate the basic drug qualities of actives.
CO-ADD will screen your compounds for free and make no claim to IP
