The Global Tuberculosis Crisis & MenT3 Target
Tuberculosis (TB) remains a leading global health threat, exacerbated by increasing multidrug resistance. Mycobacterium tuberculosis (Mtb) utilizes the MenT3 toxin to inhibit protein synthesis, promoting its survival under stress. This makes MenT3 a critical, underexplored target for novel anti-TB drug development.
AI-Driven Drug Discovery for Rapid Innovation
Traditional drug discovery is time-consuming and expensive. Our approach leverages advanced Artificial Intelligence (AI) and physics-based computational methods, integrated on the SilicoXplore platform, to rapidly identify and validate potential MenT3 inhibitors. This hybrid methodology streamlines the screening of vast chemical spaces, predicting molecular interactions and stability with high accuracy, drastically accelerating lead compound identification.
A Comprehensive AI/Physics-Based Pipeline
Our robust drug discovery pipeline began with the generation of 100,000 novel compounds using REINVENT4, a generative AI model. These were sequentially filtered to identify optimal candidates:

Identification of Potent Inhibitors for Experimental Validation
Streamlined Candidate Selection
Challenge: The initial pool of 100,000 generated molecules presented an immense challenge for traditional experimental validation.
Solution: By integrating generative AI with multi-stage computational filtering—including ADMET-AI, PharmacoNet, molecular docking, similarity searches, and advanced simulations—we systematically narrowed down the chemical space.
Results: This process efficiently identified 5 highly potent and stable lead candidates, dramatically accelerating the path towards experimental testing and potential drug development. MenT3_M2 emerged as a top performer with a binding free energy of -46.71 kcal/mol, surpassing the reference compound CTP.
Five Promising MenT3 Inhibitor Candidates
Through rigorous virtual screening and simulation, five molecules (MenT3_M1 to MenT3_M5) were identified as highly promising MenT3 inhibitors. These candidates demonstrated superior or comparable binding affinities and stability profiles compared to the natural substrate, CTP.
