Identification of inhibitors of the Salmonella FraB deglycase, a drug target

open access: yesFEBS Open Bio, Volume 15, Issue 5, Page 773-792, May 2025.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.
