Formulation of nanoparticles ribosome inactivating proteins from Mirabilis jalapa L. (RIP MJ) conjugated AntiEpCAM antibody using low chain chitosan-pectin and cytotoxic activity against breast cancer cell line.

Ribosome Inactivating Proteins (RIPs) isolated from Mirabilis jalapa L. (MJ protein) leaves showed high cytotoxic effect on malignant. Chitosan nanoparticles have frequently been used in protein delivery applications.

Formulation and Cytotoxicity of Ribosome-Inactivating Protein Mirabilis Jalapa L. Nanoparticles Using Alginate-Low Viscosity Chitosan Conjugated with Anti-Epcam Antibodies in the T47D Breast Cancer Cell Line.

Ribosome-inactivating protein (RIP) from Mirabilis jalapa L. leaves has cytotoxic effects on breast cancer cell lines but is less toxic towards normal cells. However, it can easily be degraded after administration so it needs to be formulated into nanoparticles to increase its resistance to enzymatic degradation.
