IP6C is a specific inhibitor and phage sensitizer targeting type II Thoeris systems. IP6C competitively binds to histidine in the catalytic pocket of ThsB, blocks the production of the His-ADPR alarm signal and inhibits ThsA activation, thereby relieving bacterial stasis of phage replication. IP6C selectively resensitizes drug-resistant bacteria carrying type II Thoeris systems (such as Pseudomonas aeruginosa) to phage lysis, without affecting other bacteria, and shows no toxicity to mice and human cell lines. IP6C significantly improves the survival rate of infected mice, and can be used to overcome bacterial phage defense mechanisms and study Pseudomonas aeruginosa infections[1].Thoeris system: (named after the Egyptian goddess of fertility and protection), is a widespread anti-phage immune defense system in bacteria and archaea. Thoeris system belongs to the Abortion Infection (Abi) mechanism of bacteria: when an individual bacterium detects phage invasion, it initiates a suicide program and dies, thereby blocking phage replication and spread, and protecting the surrounding bacterial population from infection.
