Abstract
![]()
An azide-functionalized
12-armed Buckminster fullerene has been
monosubstituted in organic media with a substoichiometric amount of
cyclooctyne-modified oligonucleotides. Exposing the intermediate products
then to the same reaction (i.e., strain-promoted alkyne–azide
cycloaddition, SPAAC) with an excess of slightly different oligonucleotide
constituents in an aqueous medium yields molecularly defined monofunctionalized
spherical nucleic acids (SNAs). This procedure offers a controlled
synthesis scheme in which one oligonucleotide arm can be functionalized
with labels or other conjugate groups (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic
acid, DOTA, and Alexa-488 demonstrated), whereas the rest of the 11
arms can be left unmodified or modified by other conjugate groups
in order to decorate the SNAs’ outer sphere. Extra attention
has been paid to the homogeneity and authenticity of the C60-azide scaffold used for the assembly of full-armed SNAs.

Abstract
MicroRNAs (miRNAs) are endogenous, small, noncoding ribonucleic acids (RNAs) that bind to the 3' untranslated regions of messenger RNAs (mRNAs) and induce translational repression or mRNA degradation. Although numerous studies have reported that miRNAs are of potential use for disease diagnostics and gene therapy, little is known about their fates in vivo. This study elucidated the whole-body distributions and kinetics of intravenously administered miRNA-targeting molecules in vivo by positron emission tomography (PET) imaging. A 22-mer sequence targeting miR-15b was conjugated with three different chelators and labeled with gallium-68 (68Ga). These tracers were compared with a scrambled 22-mer sequence; 22-mer with two single base substitutions; anti-miR-34 22-mer; hexathymidylate (T6), a 6-mer sequence; and an unconjugated chelator. miR-15b was chosen as a target because it is important for bone remodeling. All three 68Ga-labeled anti-miR-15b molecules had similar biodistributions and kinetics, and they all accumulated in the bones, kidneys, and liver. The bone accumulation of these tracers was the highest in the epiphyses of long tubular bones, maxilla, and mandible. By contrast, the scrambled 22-mer sequence, the 6-mer, and the unconjugated chelator did not accumulate in bones. PET imaging successfully elucidated the distributions and kinetics of 68Ga-labeled chelated miRNA-targeting molecules in vivo. This approach is potentially useful to evaluate new miRNA-based drugs.

Abstract
meso-Tris(pyridin-4-yl)(4-carboxyphenyl)porphyrin and 2-(1-hexyloxyethyl)-2-devinyl pyropheophorbide-a (Photochlor, HPPH) were amide-coupled to 1R,2S,3R,4R-2,3-dihydroxy-4-(hydromethyl)-1-aminocyclopentane and immobilized via an ester linkage to long chain alkyl amine-derivatized controlled pore glass (LCAA-CPG). The applicability of these supports (5 and 6) for the synthesis of porphyrin conjugates with oligomeric biomolecules was demonstrated using an automated phosphoramidite coupling chemistry. Cleavage from the support with concentrated ammonia gave the products, viz., porphyrin conjugates of oligonucleotides (7-9) and dendritic glycoclusters (10-13) and a cyclooctyne derivative (14) in 23-58% yield. In addition, the synthesized cyclooctyne derivative of meso-tris(pyridin-4-yl)(4-carboxyphenyl)porphyrin (14) was conjugated with an azidopropyl-modified hyaluronic acid (19). The hyaluronic acid-porphyrin conjugate (15) was radiolabeled with (64)Cu and its (15[(64)Cu]) receptor binding affinity to CD44-expressing tumor cells was evaluated.

Abstract
Synthesis for (68)Ga-labeled 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA)-chelated oligonucleotide hyaluronan (HA) tetra- and hexasaccharide conjugates is described. A solid-supported technique is used to introduce NOTA-chelator into the 3'-terminus of oligonucleotides and a copper-free strain promoted azide alkyne cycloaddition (SPAAC) to HA/oligonucleotide conjugation. Protecting group manipulation, required for the HA-moieties, is carried out after the SPAAC-conjugation. Positron emission tomography (PET) is used (1) in the whole-body distribution kinetic studies of the conjugates in healthy rats and (2) to show the potential of hyaluronan-induced targeting of oligonucleotides into the infarcted area of rats with myocardial infarction.

Abstract
Today, radiopharmaceuticals belong to the standard instrumentation of nuclear medicine, both in the context of diagnosis and therapy. The majority of radiopharmaceuticals consist of targeting biomolecules which are designed to interact with a disease-related molecular target. A plethora of targeting biomolecules of radiopharmaceuticals exists, including antibodies, antibody fragments, proteins, peptides and nucleic acids. Nucleic acids have some significant advantages relative to proteinaceous biomolecules in terms of size, production, modifications, possible targets and immunogenicity. In particular, aptamers (non-coding, synthetic, single-stranded DNA or RNA oligonucleotides) are of interest because they can bind a molecular target with high affinity and specificity. At present, few aptamers have been investigated preclinically for imaging and therapeutic applications. In this review, we describe the use of aptamers as targeting biomolecules of radiopharmaceuticals. We also discuss the chemical modifications which are needed to turn aptamers into valuable (radio-)pharmaceuticals, as well as the different radiolabeling strategies that can be used to radiolabel oligonucleotides and, in particular, aptamers.

Abstract
(68)Ga labelled 2'-O-methyl oligoribonucleotides (anti-miR-15b) bearing one, three or seven d-galactopyranoside residues have been prepared and their distribution in healthy rats has been studied by positron emission tomography (PET). To obtain the heptavalent conjugate, an appropriately protected 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA) precursor bearing a 4-[4-(4,4'-dimethoxytrityloxy)butoxy]phenyl side arm was first immobilized via a base labile linker to the support and the oligonucleotide was assembled on the detritylated hydroxyl function of this handle. A phosphoramidite building block bearing two phthaloyl protected aminooxy groups and one protected hydroxyl function was introduced into the 5'-terminus. One acetylated galactopyranoside was coupled as a phosphoramidite to the hydroxyl function, the phthaloyl protections were removed on-support and two trivalent galactopyranoside clusters were attached as aldehydes by on-support oximation. A two-step cleavage with aqueous alkali and ammonia released the conjugate in a fully deprotected form, allowing radiolabelling with (68)Ga in solution. The mono- and tri-galactose conjugates were obtained in a closely related manner. In vivo imaging in rats with PET showed remarkable galactose-dependent liver targeting of the conjugates.

Abstract
Alkylation of the hydrobromide salts of 1,4,7-tris(methoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane and 1,4,7-tris(ethoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane with appropriate α-bromoacetamides, followed by hydrolysis, provides convenient access to 10-(2-alkylamino-2-oxoethyl)-1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid derivatives that contain acid-sensitive functional groups. The utility of the method is demonstrated by improved syntheses of two known DOTA monoamides bearing acid-sensitive ω-tritylthio alkyl chains in much higher yields based on cyclen as the starting material.

Abstract
Positron Emission Tomography (PET) experienced accelerated development and has become an established method for medical research and clinical routine diagnostics on patient individualized basis. Development and availability of new radiopharmaceuticals specific for particular diseases is one of the driving forces of the expansion of clinical PET. The future development of the ⁶⁸Ga-radiopharmaceuticals must be put in the context of several aspects such as role of PET in nuclear medicine, unmet medical needs, identification of new biomarkers, targets and corresponding ligands, production and availability of ⁶⁸Ga, automation of the radiopharmaceutical production, progress of positron emission tomography technologies and image analysis methodologies for improved quantitation accuracy, PET radiopharmaceutical regulations as well as advances in radiopharmaceutical chemistry. The review presents the prospects of the ⁶⁸Ga-based radiopharmaceutical development on the basis of the current status of these aspects as well as wide range and variety of imaging agents.
