CC4CARB is an innovative chemistry center focused on the synthesis and delivery of rationally designed focused libraries to the scientific community for use in Gram-negative antibacterial drug discovery programs. The ultimate objective of CC4CARB is to create a large collection of chemical matter specifically targeting Gram-negative antimicrobial drug discovery.

The following video further describes the CC4CARB program:

Compounds synthesized within the CC4CARB program will be tested by NIAID under a separate contract for the minimum inhibitory concentrations (MICs) against select drug-resistant and wild type strains of Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus, and Neisseria gonorrhoeae.

Under the Scaffold Proposal header, we welcome the scientific community to submit ideas for antibiotic scaffolds to support this initiative.

Your Scaffold Proposal will be reviewed by an independent Scientific Advisory Board in conjunction with key persons at NIAID and RTI.

The external PI of an accepted proposal will be eligible for up to 10 hours of compensated time to help design and follow the progress of the compounds synthesized under their proposed scaffold.

Diagram showing workflow process. First path shows Applicant Idea (CDA/NDA Optional) going to CC4CARB Submission Online and then Administrative Review. If revising application, back to Applicant Idea, but if accepted then SAB Scientific Review. If improving idea, back to Applicant Idea, but if accepted then Library Design in Collaboration with Submitter. Then, Individual Library Production Plan and then COR Review. After COR Review, if Not Programmatic, back to Applicant Idea. After COR Review, if Redesigning Library, then Library Design in Collaboration with Submitter. After COR Review, if Individual Library Production Plan in queue, then Compound Synthesis, and then Added to CC4CARB Collection. Second path shows Applicant Request Compounds through Iterative Design going to Library Design in Collaboration with Submitter, and Applicant Request Compounds back and forth with Added to CC4CARB Collection.

If you wish to discuss your submission with an RTI team member, please email the project email address at or call (833) 870-0484.

RTI shall preserve the confidentiality of proposals submitted to the center except where disclosure is required by law (Freedom of Information Act); however, compounds made from proposals submitted under CC4CARB will be publicly disclosed. See Proposal Confidentiality Policy.

The Chemistry Center for Combating Antibiotic Resistant Bacteria (CC4CARB) is a NIH NIAID lead initiative
contracted with RTI International. CC4CARB is a free service completely supported by NIH NIAID.
