NeuroClick: Advanced Software for Designing Blood−Brain Barrier‐Permeable Drugs Using Click Reaction Simulations

NeuroClick is a software tool designed for the in silico execution of azide-alkyne cycloaddition reactions, commonly known as click reactions. We developed this graphical user interface application to expedite the drug discovery process by generating libraries of 1,2,3-triazole compounds. NeuroClick enables users to input reagent SMILES strings, rapidly generating and screening extensive combinatorial libraries at a pace of 10,000 molecules per minute. The software applies stringent criteria to ensure the relevance and accuracy of the generated compounds, excluding molecules without azide groups or those with multiple reactive functional groups to maintain dataset integrity. NeuroClick incorporates advanced filtering options based on Lipinski's rule of five and blood-brain barrier (BBB) permeability predictors, allowing researchers to identify drug-like molecules with potential central nervous system activity. The software's high-throughput and user-friendly interface significantly enhance the efficiency of early-stage drug development by facilitating the exploration of vast chemical spaces and identifying promising lead compounds for further development. This article provides comprehensive guidance on the installation, usage, and features of NeuroClick, ensuring that users can leverage its full potential in their research endeavors. © 2024 Wiley Periodicals LLC.
