In January 2025, another POLEPI project publication entitled “Biodistribution of Polyaldehydedextran Nanoparticle Encapsulated Epirubicin in Ovarian Tumor-Bearing Mice via Optical Imaging” was published in the International Journal of Molecular Sciences.
The publication describes the development and biodistribution studies of POLEPI, a polysaccharide nanoparticle with epirubicin, and pure epirubicin hydrochloride. Experiments were carried out on mice with the orthotopic ovarian tumor model CRT_OV_00367 and on mice without tumor, using the inherent fluorescence of epirubicin to image the concentration. Measurements were made at five different time points (1, 3, 6, 24 and 48 hours) after a single dose.
The results showed that POLEPI uptake in tumors was higher than in healthy ovaries, with the highest accumulation ratio in tumor tissue relative to healthy tissue observed between 6 and 24 hours after administration. The published results demonstrate that POLEPI shows increased accumulation and retention in tumor tissue compared to pure drug, with preferential distribution to orthotopic ovary with tumor compared to healthy ovarian tissue.
