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 .
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.

With the aging population and increasing competitive pressures, neurodegenerative diseases of the central nervous system (CNS) have become a serious medical challenge in modern society, including Parkinson's disease, Alzheimer's disease, brain tumors, and multiple sclerosis. However, the success rate of CNS drug development remains remarkably low, primarily due to the blood-brain barrier (BBB). The blood-brain barrier (BBB) is a semipermeable barrier structure that surrounds the microvasculature of the CNS. In capillaries, the wedged endothelial cells are tightly packed and wedge-shaped, lining the interior of the vessels to form extensive tight junctions. Along with a range of receptors, transporters, efflux pumps, and other cellular components, this barrier regulates the entry and exit of molecules between the bloodstream and the brain. The intact BBB blocks the passage of most blood-borne substances into the brain, preventing nearly 100% of large-molecule drugs and over 98% of small-molecule drugs from entering. Compared to non-CNS drugs, physicochemical properties such as hydrogen bonds, lipophilicity, and molecular weight significantly influence a compound's ability to cross the BBB. Using artificial intelligence (AI) algorithms to predict BBB permeability, a predicted value greater than 0.75 indicates that the compound has strong potential to cross the BBB, providing a promising starting point for CNS drug discovery.
