In an attempt to visualize folate receptors that overexpress on many cancers, [(18)F]-fluorobenzene and pyridinecarbohydrazide-folate/methotrexate conjugates ([(18)F]-1, [(18)F]-2-folates and [(18)F]-8, [(18)F]-9-MTXs) were synthesized by the nucleophilic displacement reactions using ethyl-trimethylammonium-benzoate and pyridinecarboxylate precursors. The(More)
There is a need to develop more potent radiofluorinated folic acid conjugates for a better visualization of folate receptors that overexpress on many human cancers. Due to the clinical importance of [(18)F]-fluoro-2-deoxy-d-glucose ([(18)F]-FDG) and its availability in almost every positron-emission tomography center, new radiofluorinated [(18)F]-FDG-folate(More)
BACKGROUND The limitation of current breast cancer treatments was elucidated by the presence of cancer stem cells (CSCs) that play essential role in cancer initiation, progression, resistance, recurrence and metastasis. Materials & methods: Biocompatible multimodality single-walled carbon nanotube (SWCNT) nanoprobes were developed. The biodistribution and(More)
PURPOSE The goal of this study was to prepare a synthetic peptide derived from breast tumor associated antigen and to evaluate its potential as a breast cancer imaging agent. METHODS A mucin 1 derived peptide was synthesized by solid-phase peptide synthesis and examined for its radiochemical and metabolic stability. The tumor cell binding affinity of(More)
Conjugation of the cytotoxic drugs to receptor-binding peptides is an attractive approach for the targeted delivery of cytotoxic peptide conjugates to tumor cells. In an attempt to develop an efficient peptide-based radiopharmaceutical for targeting bombesin (BN) receptor-expressing tumors (i.e., breast and prostate), we have prepared by solid-phase peptide(More)
Despite their advantageous chemical properties for nuclear imaging, radioactive sodium-22 ((22)Na) tracers have been excluded for biomedical applications because of their extremely long lifetime. In the current study, we proposed, for the first time, the use of (22)Na radiotracers for pre-clinical applications by efficiently loading with silica(More)
