Design, Synthesis and Labeling of Tripeptide Derivatives with 99mTc as Hypoxia Imaging Agents
Background: Many diseases, including cancer, ischemia and tumors show degrees of tissue hypoxia.Therefore, it is useful to detect tissue hypoxia with compounds that can penetrate and remain in hypoxic cells in order to diagnose cancer at early stages. Peptides with low molecular weight, susceptible to redox environment, with easier penetration into tissues and low antigenic characteristics are ...
متن کاملSynthesis and Preliminary Evaluation of a New 99mTc Labeled Substance P Analogue as a Potential Tumor Imaging Agent
Neurokinin 1 receptors (NK1R) are overexpressed on several types of important human cancer cells. Substance P (SP) is the most specific endogenous ligand known for NK1Rs. Accordingly, a new SP analogue was synthesized and evaluated for detection of NK1R positive tumors. [6-hydrazinopyridine-3-carboxylic acid (HYNIC)-Tyr8-Met(O)11-SP] was synthesized and radiolabeled with 99mTc using ethylenedia...

متن کاملTumor Imaging with 99mTc-Labelled Antibody Fragmentst
Althoughthe labelling of proteins with was established in 1964 by McAfee, et al., this isotope has been avoided by most investigators for the labelling of antibodies for tumor localization. There are several reasons for this: (1)the half-life is only 6 hours while most previous radiolabelled antibody localization studies have shown that the required tumor-toblood ratio needed for tumor visualiz...
متن کاملDesign and Synthesis of 4-flurophthalimides as potential anticonvulsant agents
Objective(s): Anticonvulsant activity of phthalimide was discovered in 2000 by molecular hybridization of thalidomide and ameltolide. In our previous research we have reported some new 4-substituted derivatives of phthalimide with good activity against the tonic and clonic seizures Material and Methods: A series of novel 4-flurophthalimides that designed using bioisosteric replacement were synt...
