Pre-gestational diabetes (PGD), encompassing type 1 and type 2 diabetes diagnosed prior to conception, is a chronic metabolic disorder characterized by persistent hyperglycaemia, insulin resistance, impaired glucose uptake, and dysregulated lipid metabolism, posing substantial risks to maternal and fetal health. Given the multifactorial pathophysiology of PGD and limitations of single-target pharmacotherapy during pregnancy, this study aimed to elucidate the multi-target therapeutic potential of Syzygium cumini (S. cumini) bark phytoconstituents using an integrative network pharmacology and molecular docking approach. Comprehensive phytochemical profiling of the ethanolic bark extract was conducted using GC-MS and LC-HRMS, revealing fatty acids, sterol derivatives, and a flavonoid-dominant metabolite spectrum. Sixteen representative compounds were subjected to target prediction and mapped to PGD-related genes. The Protein–protein interaction analysis and functional enrichment (GO and KEGG) identified central regulatory nodes including PPAR-γ, glucose transporter (GLUT) proteins, and insulin receptor substrates associated with insulin signaling and metabolic homeostasis. Molecular docking against five PGD-relevant proteins (PDB IDs: 2PRG, 5EQI, 7WSN, 4F1D, 4ZW9) demonstrated strong binding affinities for flavonoids (quercetin, myricetin, kaempferol) and phytosterols (-8.1 to-10.4 kcal/mol), supporting the structural plausibility of multi-target interactions. Collectively, this study provides a systems-level mechanistic framework highlighting the potential of S. cumini as a complementary multi-pathway modulator in the management of pre-gestational diabetes. © 2026, Ital Publication.
