Thrombotic disorders pose a global health threat, emphasizing the urgent need for effective management strategies. This study explores the potential of bioactive compounds derived from guava leaves in inhibiting coagulation factor IXa (CFIXa) using in silico methods. Using GC-MS, bioactive compounds extracted from guava leaf through ethanol maceration were identified. Pharmacokinetic properties were elucidated using SwissADME. Molecular docking with AutoDock Vina was used to investigate the interactions with CFIXa. CFIXa was modeled with pysimm/LAMMPS and analyzed with CastP for active site identification. The setup with a higher solvent concentration and lower surface area yielded the highest percent yield (78.541 g, 39.27%). Among the 28 identified bioactive compounds, predominantly terpenoids, only seven exhibited suitable pharmacokinetic properties for oral ingestion and drug development. Docking analysis revealed favorable binding of these compounds to CFIXa (-7.6:-5.3). This study shows inhibition of coagulation factor IXa, thus bridging the ambiguity surrounding the effect of guava leaves on hemostasis. These findings also reveal that guava leaf extract harbors bioactive compounds with potential as coagulation pathway inhibitors, promising novel avenues for thrombotic disorder management.
