    Aim: To design D-Mannose conjugated 5-Fluorouracil (5-FU) loaded Jackfruit seed starch nanoparticles (JFSSNPs) for site-specific delivery. Background: Liver cancer is the third leading cause of death in the world and the fifth most often diagnosed cancer. It is a major global threat to public health. Treatment of liver cancer with conventional method bears several side effects, thus to undertake these side effects as a formulation chal-lenge, it is necessary to develop novel target-specific drug delivery system for the effective and bet-ter localization of drug into the proximity of target with restricting the movement of the drug in normal tissues. Objective: To optimize and characterize the developed D-Mannose conjugated 5-Fluorouracil (5--FU) loaded Jackfruit seed starch nanoparticles (JFSSNPs) for effective treatment of liver cancer. Materials and Methods: 5-FU loaded JFSSNPs were prepared and optimized formulations having higher encapsulation efficiency were conjugated with D-Mannose. These formulations were characterized for size, morphology, zeta potential, X-Ray Diffraction, and Differential Scanning Calorimetry. The potential of NPs was studied using in vitro cytotoxicity assay, in vivo kinetic studies, and bio-distribution studies. Result and Discussion: 5-Fluorouracil loaded NPs had a particle size between 336 to 802nm with drug entrapment efficiency between 64.2 to 82.3%. In XRD analysis, 5-FU peak was diminished in the diffractogram, which could be attributed to the successful incorporation of the drug in amorp-hous form. DSC study suggests there was no physical interaction between 5-FU and Polymer. NPs showed sustained in vitro 5-FU release up to 2 hours. In vivo, mannose conjugated NPs prolonged the plasma level of 5-FU and assisted in the selective accumulation of 5-FU in the liver (vs. other organs spleen, kidney, lungs, and heart) compared to unconjugated one and plain drug. Conclusion: In vivo, bio-distribution, and plasma profile studies resulted in a significantly higher concentration of 5-Fluorouracil liver, suggesting that these carriers are efficient, viable, and targeted carrier of 5-FU treatment of liver cancer. � 2021 Bentham Science Publishers.
