PathGennie is an open-source computational framework developed by researchers at S.N. Bose National Centre for Basic Sciences, Kolkata. The method simulates how a drug molecule unbinds from a protein, helping researchers estimate residence time and screen drug candidates more efficiently. The Department of Science and Technology describes it as a breakthrough for affordable drug discovery because freely available computational tools can reduce the time and cost of early-stage drug research. Being open-source, the software can be used freely by pharmaceutical companies and research institutions worldwide.
