Background
2
Poly(ADP-ribose) polymerase (PARP) is an important therapeutic target in cancer treatment
and dynamic assessment of its expression level is essential for achieving precision therapy.
Purpose
2
This study aims to assess the feasibility of using a novel albumin-binding PARP-targeted PET imaging probe for detecting PARP expression levels.
Methods
2
Firstly
based on the core structure of the PARP inhibitor Olaparib
the precursor NOTA-LA was synthesized using 4-(4-fluoro-3-(piperazine-1-carbonyl)benzyl) phthalazin-1(2H)-one and 4-(4-iodophenyl) butanoic acid as starting materials. Then
the target imaging probe
[
18
F
]
AlF-NOTA-LA
was radiolabeled
via
the non-covalent [
18
F
]
AlF method
and the probe was then characterized by determining its radiolabeling yield
radiochemical purity
molar activity
partition coefficient
and
in vitro
stability. Finally
the imaging performance of [
18
F
]
AlF-NOTA-LA was evaluated through
in vitro
cell-based assays and
in vivo
microPET imaging studies in A549 and MDA-MB-453 tumor-bearing mice.
Results
2
The radiolabeling of [
18
F
]
AlF-NOTA-LA is completed in approximately 15 min
yielding a radiolabeling efficiency of (49.2±2.5)%
with radiochemical purity exceeding 99%
a molar activity of 3.14 GBq∙μmol
-1
a log
P
value of -1.1±0.013
and excellent in vitro stability. After 60 min
the cellular uptake of [
18
F
]
AlF-NOTA-LA in MDA-MB-453 cells is (3.83±0.26)%AD
significantly higher than that in A549 cells (1.89±0.12)%AD. MicroPET imaging reveals that in MDA-MB-453 tumor-bearing mice
the probe's tumor uptake peaks at 10 min
reaching a maximum value of (5.31±0.20)%ID∙g
-1
(percentage injected dose per gram of tissue). In contrast
A549 tumor-bearing mice and blocking group showed significantly lower peak uptakes of (3.04±0.03)%ID∙g
-1
and (2.23±0.11)%ID∙g
-1
respectively.
Conclusions
2
Preliminary preclinical findings in this study indicate that the probe exhibited suboptimal pharmacokin
etic properties
in vivo
. Following structural modifications
it is anticipated to have potential as a PARP-targeted PET imaging probe.
