The development of a biomarker for hypoxic tissues is essential both for diagnostic formulation and treatment planning for most cancer patients.
Although the current PET radiotracers are non-invasive imaging modality techniques of tumor hypoxia, they are not being used routinely due to slow uptake by hypoxic.
Cu(II)-tracers have been suggested to become one of the most promising PET agents for hypoxia imaging. However, one of the main drawback of Cu(II)-ATSM compounds is that they can also dissociate Cu(II) in normal and hypoxia cell, causing to chelation of Cu(II) by SOD and cytochrome C, and other rich proteins causing to:
- Unwanted cellular reactions resulting in toxicity
- Low signal to background ratio of the radiotracer
- Specificity problems
We present a novel 64Cu(II) based radiotracer that is incorporated in the copper cycle.
The Commercial Benefit
Our product is a new 64Cu based radiotracer for hypoxia, based on molecular level understanding of the cellular transfer mechanism, rate, stability, and oxidation/reduction behavior. The novelty of this work is that it uses basic and fundamental knowledge on the cellular copper cycle, and generates a new compound that competes with the normal copper cycle, and its transfer mechanism is known and tracked in detail.
In a nutshell, our cutting-edge innovation is significantly superior to any other current radiotracers for hypoxia as:
- Its uptake ratio by the cell is high
- It is highly sensitive to the oxidation environment
The global medical imaging devices market is expected to generate revenue of $46.65 billion by 2023, growing at a CAGR of 5.47% during the forecast period. The introduction of innovative systems such as fusion imaging enabled CT/PET devices will contribute to the development of the medical imaging market during the forecast period.
PET-CT Scanner Device Market accounted for $1,454 million in 2016 and is estimated to reach $2,108 million by 2023, growing at a CAGR of 5% during the analysis period. There is a high prevalence of diseases worldwide, hence an increase in the need of diagnosis.

Hypoxia is not only characteristic in solid tumors, but can also be found in plaques of α-synuclein, and αβ amyloids hence can diagnose Alzheimer's and Parkinson's diseases as well. We set our sights on these challenging directions.
