Scope of this study is to synthesize a nano-dendrimer and its conjugate with C595 MAb against breast cancer cell, followed by its chelating agent with Gd3+. At the end, its use as a dual nanosized probe for detection and treatment was investigated. Anti-MUC-1 MAb C595 was coupled to a biodegradable biocompatible anionic linear globular dendrimer, ALGDG2, Poly ethylene glycol PEG core and citric acid shell followed by loading with Gd3+ to make novel MR imaging contrast agents. Anticancer effects and MR imaging parameters of the prepared nanoconjugate was investigated in vitro: cell toxicity, apoptosis and TNF-alpha, hemolysis, LDH evaluations as well as toxicity, biodistribution and MR imaging of cancer place were investigated. Results showed good tumor accumulation and detection, no in vivo toxicity, and potential selective anti-breast cancer activity. In conclusion, findings of this study showed that Gd3+-ALGDG2-C595 nano-probe is potentially both, a selective breast molecular imaging tool as well as a therapeutic agent. Further, subsequent clinical trials appear warranted.
