Open Source Antibiotics is a consortium of researchers interested in open ways to discover and develop new, inexpensive medicines for bacterial infections.

There are already a couple of projects Mur Ligase and a series of Diarylimidazoles with unknown mechanism. Well worth a read.

All the structures of the molecules on the project are openly available in a spreadsheet https://docs.google.com/spreadsheets/d/168-a1_l51Nfbms67eG8zU8p-EhEtEO26FUzRInbu7fY/edit#gid=2078630269 feel free to have a browse.
