Abstract

The current study explores the synthesis, structural characterization, and pharmacological assessment of 9,9-dibutylfluorene-2-carboxylic acid, focusing on its potential as an inhibitor of dihydrofolate reductase (DHFR), a crucial enzyme in cancer treatment. SC-XRD confirmed its molecular structure, detailing essential bond lengths and angles, while Hirshfeld surface analysis identified significant intermolecular interactions primarily driven by H-bonding and van der Waals forces. Density Functional Theory (DFT) revealed stable electronic properties, providing deeper insight into the optimized geometric parameters. Molecular docking established a strong binding affinity to DHFR, indicating promising inhibitory effects. Furthermore, pharmacokinetic analysis suggested favorable drug-like properties, including high gastrointestinal absorption. Together, the findings present this compound as a fascinating candidate for future development as a fluorene-based anticancer agent.
