Abstract
![]()
Matrix metalloproteases (MMPs) have
been found to be highly expressed
in a variety of malignant tumor tissues. Noninvasive visualization
of MMP activity may play an important role in the diagnosis of MMP
associated diseases. Here we report the design and synthesis of a
set of fluorine-19 dendron-based magnetic resonance imaging (MRI)
probes for real-time imaging of MMP-2 activity. The probes have the
following features: (a) symmetrical fluorine atoms; (b) the number
of fluorine atoms can be increased through facile chemical modification;
(c) readily accessible peptide sequence as the MMP-2 substrate; (d)
activatable 19F signal (off/on mode) via paramagnetic metal
ion incorporation. Following optimization for water solubility, one
of the probes was selected to evaluate MMP-2 activity by 19F magnetic resonance spectroscopy (MRS). Our results showed that
the fluorine signal increased by 8.5-fold in the presence of MMP-2.
The specific cleavage site was verified by mass spectrometry. The
selected probe was further applied to detect secreted MMP-2 activity
of living SCC7 squamous cell carcinoma cells. The fluorine signal
was increased by 4.8-fold by MRS analysis after 24 h incubation with
SCC7 cells. This type of fluorine probe can be applied to evaluate
other enzyme activities by simply tuning the substrate structures.
This symmetrical fluorine dendron-based probe design extends the scope
of the existing 19F MRI agents and provides a simple but
robust method for real-time 19F MRI application.

Abstract
Thermal enzyme deactivation by the imidazolium-presenting silica nanoparticles with the microwave irradiation is presented in this manuscript. The modified nanoparticles were synthesized, and it was observed that the modified nanoparticles can be a heat source in the buffer under the weak-power microwave irradiation. Finally, based on the heat-generating ability of these nanoparticles, deactivation of glutathione reductase and alkaline phosphatase with the modified nanoparticles were demonstrated.
