Original Article


Phytic acid (PA) has momentous chemotherapeutic potential. Due to the chelate formation and rapid elimination, it is not popular in cancer treatment. The present work was inquested to develop a surface-modified nanoformulation of PA which prevents its speedy elimination and maximizes chemotherapeutic action. Chloroauric acid was reduced with pectin to produce pectin-gold nanoparticles (PGNPs). PGNPs were incubated with PA and jacalin for drug loading and surface modifications, respectively, to form PA-loaded jacalin-pectin-gold nanoparticles (PA-J-PGNPs). Formulation(s) were assessed for various pharmaceutical/pharmacological parameters. To validate the efficacy against colon carcinogenesis, formulation(s) were assessed in 1,2-dimethylhydrazine (DMH)-treated Wistar rats. DMH treatment distorted colonic architecture, oxidative, and hemodynamic parameters, which were favorably restored by PA-J-PGNP administration. To further confirm our deliberations, formulation(s) were also examined against DMH-altered metabolic changes and expression of markers pertaining to cellular proliferation, which was reinstated by PA-J-PGNPs. Our findings establish PA formulation(s) as a promising approach for suppression of colon carcinogenesis.
