Abstract
![]()
DNA is well-known as bearer of the genetic code.
Since its structure
elucidation nearly seven decades ago by Watson, Crick, Wilkins, and
Franklin, much has been learned about its detailed structure, function,
and genetic coding. The development of automated solid-phase synthesis,
and with it the availability of synthetic DNA with any desired sequence
in lengths of up to hundreds of bases in the best case, has contributed
much to the advancement of the field of DNA research. In addition,
classic organic synthesis has allowed introduction of a very large
number of modifications in the DNA in a sequence specific manner,
which have initially been targeted at altering the biological function
of DNA. However, in recent years DNA has become a very attractive
scaffold in supramolecular chemistry, where DNA is taken out of its
biological role and serves as both stick and glue molecule to assemble
novel functional structures with nanometer precision. The attachment
of functionalities to DNA has led to the creation of supramolecular
systems with applications in light harvesting, energy and electron
transfer, sensing, and catalysis. Functional DNA is clearly having
a significant impact in the field of bioinspired nanosystems. Of particular interest is the use of porphyrins in supramolecular
chemistry and bionanotechnology, because they are excellent functional
groups due to their electronic properties that can be tailored through
chemical modifications of the aromatic core or through insertion of
almost any metal of the periodic table into the central cavity. The
porphyrins can be attached either to the nucleobase, to the phosphate
group, or to the ribose moiety. Additionally, noncovalent templating
through Watson–Crick base pairing forms an alternative and
attractive approach. With this, the combination of two seemingly simple
molecules gives rise to a highly complex system with unprecedented
possibilities for modulation of function, and with it applications,
particularly when combined with other functional groups. Here, an
overview is given on the developments of using porphyrin modified
DNA for the construction of functional assemblies. Strategies for
the synthesis and characterization are presented alongside selected
applications where the porphyrin modification has proven to be particularly
useful and superior to other modifiers but also has revealed its limitations.
We also discuss implications on properties and behavior of the porphyrin–DNA,
where similar issues could arise when using other hydrophobic and
bulky substituents on DNA. This includes particularly problems regarding
synthesis of the building blocks, DNA synthesis, yields, solubility,
and intermolecular interactions.

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
Porphyrins were attached to LNA uridine building blocks via rigid 5-acetylene or more flexible propargyl-amide linkers and incorporated into DNA strands. The systems show a greatly increased thermodynamic stability when using as little as three porphyrins in a zipper arrangement. Thermodynamic analysis reveals clustering of the strands into more ordered duplexes with both greater negative ΔΔS and ΔΔH values, and less ordered duplexes with small positive ΔΔS differences, depending on the combination of linkers used. The exciton coupling between the porphyrins is dependent on the flanking DNA sequence in the single stranded form, and on the nature of the linker between the nucleobase and the porphyrin in the double stranded form; it is, however, also strongly influenced by intermolecular interactions. This system is suitable for the formation of stable helical chromophore arrays with sequence and structure dependent exciton coupling.

Abstract
The binding of telomerase inhibitor ZnTMPyP(3+)-ImPzn, Zn(II) derivative of tricationic porphyrin-imidazophenazine conjugate, to tetramolecular quadruplex structure formed by poly(G) was studied in aqueous solutions at neutral pH and near physiological ionic strength using absorption and polarized fluorescent spectroscopy techniques. Three binding modes were determined from the dependences of the fluorescence intensity and polarization degree for the porphyrin and phenazine moieties of the conjugate on molar polymer-to-dye ratio (P/D). The first one is outside electrostatic binding of positively charged porphyrin fragments to anionic phosphate groups of the polymer which prevails only at very low P/D values and manifests itself by substantial fluorescence quenching. It is suggested that the formation of externally bound porphyrin dimers occurs. The other two binding modes observed at high P/D are embedding of the ZnTMPyP(3+) moiety into the groove of poly(G) quadruplex accompanied by more than 3-fold enhancement of the conjugate emission, and simultaneous intercalation of the phenazine fragment between the guanine bases accompanied by the increase of its fluorescence polarization degree up to 0.25. Thus Zn(II) conjugate seems to be promising ligand for the stabilization of G-quadruplex structures since porphyrin binding to poly(G) is strengthened by additional intercalation of phenazine moiety.

Abstract
Binding of a novel cationic porphyrin-imidazophenazine conjugate, TMPyP(3+)-ImPzn, to four-stranded poly(G) was investigated in aqueous solutions of neutral pH under near physiological ionic conditions using absorption, polarized fluorescent spectroscopy and fluorescence titration techniques. In absence of the polymer the conjugate folds into stable internal heterodimer with stacking between the porphyrin and phenazine chromophores. Binding of TMPyP(3+)-ImPzn to poly(G) is realized by two competing ways. At low polymer-to-dye ratio (P/D < 6) outside electrostatic binding of the cationic porphyrin moieties of the conjugate to anionic polynucleotide backbone with their self-stacking is predominant. It is accompanied by heterodimer dissociation and distancing of phenazine moieties from the polymer. This binding mode is characterized by strong quenching of the conjugate fluorescence. Increase of P/D results in the disintegration of the porphyrin stacks and redistribution of the bound conjugate molecules along the polymer chain. At P/D > 10 another binding mode becomes dominant, embedding of TMPyP(3+)-ImPzn heterodimers into poly(G) groove as a whole is occurred.

Abstract
Cationic porphyrin-anthraquinone hybrids bearing peripheral substituents, either pyridine, imidazole, or pyrazole rings have been investigated for their binding mode to DNA duplexes. The four kinds of DNA duplexes were used, which represent intercalation and groove binding modes. AutoDock 4.2 was used to dock nine hybrid compounds to four DNA duplexes, while monitoring of conformational changes of four best hybrid-DNA complexes during 2 ns was performed by Amber9 molecular dynamics package. The binding energy calculation of best four complexes was then carried out using MMPBSA method. The hybrid compounds interacted to DNA duplexes through intercalation and groove binding modes. The minor groove binding of DNA was energetically preferred by cationic porphyrin hybrids due to favorable electrostatic and van der Waals interactions. Both electrostatic and van der Waals contributions were able to distinguish the binding mode of porphyrin hybrid to DNA duplexes.

Abstract
Recent developments in DNA-mediated nanostructuring have paved the way for the development of novel reaction centers. As part of a project focused on nanostructured reaction centers for reactions catalyzed by porphyrins, we have developed a solid-phase synthesis of tetrakis(p-hydroxyphenyl)porphyrin-oligonucleotide hybrids. In these hybrids, up to four nucleic acid chains are linked to the phenolic substituents of the porphyrin via phosphodiester linkages. A representative hybrid with one oligonucleotide chain of the sequence TTAA was found to survive light irradiation under aerobic conditions for 2 h with less than 35% oxidation of the DNA chain. An assay measuring the diastereo- and enantioselectivity of the photosensitized ene reaction of mesitylol with singlet oxygen was set up that provides diastereomeric ratios via NMR of aliquots of the reaction solution. Enantiomers were separated gas chromatographically on a chiral stationary phase and were assigned based on the product distribution obtained with an enantiomerically enriched starting material. Our results are a starting point for the exploration of nanostructured reaction media based on DNA and porphyrins.

Abstract
The synthesis of three novel axial dinucleosides was successfully accomplished. The compounds are 5″- O , 5″- O -dithymidylphosphorus(V)-meso-tetraphenylporphyrin, 5″- O , 3″- O -dithymi-dylphosphorus(V)-meso-tetraphenylporphyrin, and 3″- O , 3″- O -dithymidylphosphorus(V)tetraphenylporo-phyrin. These compounds could provide a lead toward the synthesis of an oligo-porphyrinyl DNA analogue that represents a system containing phosphorus(V)porphine units axially connected through the 5″- O -thymidine-3″- O bridges.

Abstract
A method for the solution-phase synthesis of branched oligonucleotides with tetrahedral or pseudo-octahedral geometry is described that involves the coupling of 3'-H-phosphonates of protected dinucleoside phosphates and organic core molecules. The dimer building blocks are produced by a synthesis that requires no chromatographic purification and that produces the dimer H-phosphonates in up to 44% yield in less than three days of laboratory work. A total of seven different branched hybrids were prepared, including a new hybrid of the sequence (CG)(4)TBA, where TBA stands for tetrakis(p-hydroxybiphenyl)adamantane that assembles into a material from micromolar aqueous solution upon addition of MgCl(2).

Abstract
Four new phosphorus(V) porphyrins were designed and synthesized. The compounds were diaxially substituted with 4-nitrobenzamide. The axial ligands were attached to the P(V) center of the porphyrins through methylene linkers of different lengths. DNA titrations showed the expected porphyrin binding. When exposed to 532 nm laser light, which corresponds to the porphyrin Q band, the photosensitizers induced DNA nicking. Inhibition of the nicking by sodium azide suggested participation of singlet oxygen in the process. Photoexcitation with 305 nm laser light, which corresponds to absorption of 4-nitrobenzamide, also resulted in DNA damage. Due to the lack of electronic communication between the axial ligands and the porphyrin, the desired pathway of DNA cleavage was chosen by selecting a proper wavelength of the light used for photoexcitation. The activities of the porphyrins in photoinduced DNA nicking were very similar in both experiments: irradiation with 305 and 532 nm light, and were inversely correlated with the length of the linkers.

Abstract
Using a Cu ( I )-catalyzed carbohydrate azide-alkynylphenylporphyrin cycloaddition (the so-called "click" chemistry), we have synthesized in high yields, a series of four new porphyrin-carbohydrate conjugates containing either one or four galactose or lactose moieties linked via triazole units to a meso-phenyl group of a TPP or tetrabenzoporphyrin (TBP) macrocycle. The time-dependent uptake and subcellular distribution of this series of porphyrin-carbohydrate conjugates were evaluated in human carcinoma HEp2 cells. While the three TPP conjugates accumulated to a similar extent within cells and localized mainly in the ER and endosomes, the TBP-galactose conju gate was the one most efficiently taken up by the HEp2 cells, accumulating approximately 5 times more than the TPP conjugates, and localized preferentially within the cell lysosomes.

Abstract
A synthetic methodology for the synthesis of various β-pyrrolic-functionalised porphyrins and their covalent attachment to 2'-deoxyuridine and DNA is described. Palladium(0)-catalysed Sonogashira and copper(I)-catalysed Huisgen 1,3-dipolar cycloaddition reactions were used to insert porphyrins into the structure of 2'-deoxyuridine and DNA. Insertion of a porphyrin into the middle of single-stranded CT oligonucleotides possessing a 5'-terminal run of four cytosines was shown to trigger the formation of pH- and temperature-dependent i-motif structures. Porphyrin insertion also led to the aggregation of single-stranded purine-pyrimidine sequences, which could be dissociated by heating at 90 °C for 5 min. Parallel triplexes and anti-parallel duplexes were formed in the presence of the appropriate complementary strand(s). Depending on the modification, porphyrins were placed in the major and minor grooves of duplexes and were used as bulged intercalating insertions in duplexes and triplexes. In general, the thermal stabilisation of parallel triplexes possessing porphyrin-modified triplex-forming oligonucleotide (TFO) strands was observed, whereas anti-parallel duplexes were destabilised. These results are compared and discussed on the basis of the results of molecular modelling calculations.

Abstract
PURPOSE To study the targeting and photodynamic therapy efficiency of porphyrin and galactosyl conjugated micelles based on amphiphilic copolymer galactosyl and mono-aminoporphyrin (APP) incoporated poly(2-aminoethyl methacrylate)-polycaprolactone (Gal-APP-PAEMA-PCL). METHODS Poly(2-aminoethyl methacrylate)-polycaprolactone (PAEMA-PCL) was synthesized by the combination of ring opening polymerization and reversible addition-fragmentation chain transfer (RAFT) polymerization, and then Gal-APP-PAEMA-PCL was obtained after conjugation of lactobionic acid and 5-(4-aminophenyl)-10,15,20-triphenylporphyrin (APP) to PAEMA-PCL. The chemical structures of the copolymers were characterized, and their biological properties were evaluated in human laryngeal carcinoma (HEp2) and human hepatocellular liver carcinoma (HepG2) cells. RESULTS Both APP-PAEMA-PCL and Gal-APP-PAEMA-PCL did not exhibit dark cytotoxicity to HEp2 cells and HepG2 cells. However, Gal-APP-PAEMA-PCL was taken up selectively by HepG2 cells and had the higher phototoxicity effect. Both polymers preferentially localized within cellular vesicles that correlated to the lysosomes. CONCLUSIONS The results indicated that porphyrin and galactosyl conjugated polymer micelles exhibited higher targeting and photodynamic therapy efficacy in HepG2 cells than in HEp2 cells.

Abstract
The interactions between cationic meso-tetrakis(4-(N-methylpyridiumyl))porphyrin (TMPyP4) and the G-quadruplex (G4) of human telomeric single-strand oligonucleotide d(TTAGGG)(2) (S12) have been investigated by means of circular dichroism (CD), UV-visible absorption and fluorescence spectroscopies. It is found that TMPyP4 can preferentially induce the conformational conversion of the G4 structure from the parallel type to the parallel/antiparallel mixture in the presence of K(+), and that it can directly induce the formation of antiparallel G4 structure from the single-strand oligonucleotide S12 in the absence of K(+). Furthermore, the comparable experiments of TMPyP4 with two single-strand oligonucleotides S6 d(TTAGGG) and S24 d(TAGGG(TTAGGG)(3)T) in the absence of K(+) show that TMPyP4 can also induce the formation of antiparallel G4 from S24 but not from S6, indicating that the end-loops of the G4 structure are the key factors for the formation of G4 induced by TMPyP4.

Abstract
Olignucleotide-based drugs show promise as a novel form of chemotherapy. Among the hurdles that have to be overcome on the way of applicable nucleic acid therapeutics, inefficient cellular uptake and subsequent release from endosomes to cytoplasm appear to be the most severe ones. Covalent conjugation of oligonucleotides to molecules that expectedly facilitate the internalization, targets the conjugate to a specific cell-type or improves the parmacokinetics offers a possible way to combat against these shortcomings. Since workable chemistry is a prerequisite for biological studies, development of efficient and reproducible methods for preparation of various types of oligonucleotide conjugates has become a subject of considerable importance. The present review summarizes the advances made in the solid-supported synthesis of oligonucleotide conjugates aimed at facilitating the delivery and targeting of nucleic acid drugs.

Abstract
A porphyrin that contains a single carboxylic acid group was synthesized and coupled to 2'-amino-2'-deoxyuridine. The resultant product contained a free 3' hydroxyl group and a 4,4'-dimethoxytrityl (DMT) protecting group on the 5' hydroxyl of the uridine, making it suitable for use in oligonucleotide synthesis. The 3' H-phosphonate derivative of this molecule was synthesized and used to form a conjugate with a 19 nucleotide sequence of DNA (5'-CCTCCAGTGGAAATCAAGG-3'). This was carried out with the DNA attached at the 3' end to a control pore glass (CPG) substrate, allowing for rapid purification. After removal of the DMT group, an additional three nucleotides were added, leaving the porphyrin as an internal modification. This is the first report of porphyrin attached internally to an oligonucleotide using a hydrogen-bonding nucleoside analog. This allows oligonucleotides to be used as a scaffold for precise positioning of multiple porphyrins within biomimetic arrays.

Abstract
The total syntheses of four PEG-functionalized porphyrins, containing one to four low molecular weight PEG chains linked via amide bonds to the para-phenyl positions of meso-tetraphenylporphyrin, are reported. The hydrophobic character of the PEG-porphyrins decreases with the number of PEG chains linked to the porphyrin ring, while their tendency for aggregation in buffered aqueous solution increases. The porphyrins containing one or two PEG chains accumulated within human HEp2 cells to a much higher extent than those having three or four PEGs at the macrocycle periphery. All PEG-porphyrins were found to be non-toxic in the dark, and only those containing one or two PEG chains were phototoxic (IC(50)=2 microM at 1J/cm(2) light dose). The preferential sites of subcellular localization of the porphyrins containing one or two PEG chains were found to be the mitochondria and endoplasmic reticulum (ER), while those containing three or four PEG chains localize preferentially in the lysosomes.

Abstract
Several compounds, representative of the class of lexitropsins, were analyzed by electrospray tandem mass spectrometry. The study of the fragmentations of the protonated molecular species ([M + H](+)) and of selected fragment ions allowed proposals for the main fragmentation pathways of compounds of this type. The interpretation of the fragmentation pathways of these compounds was complicated because of intramolecular hydrogen migration. In order to better understand the fragmentation pathways, the MS/MS/MS spectra of several compounds, and the MS/MS and MS/MS/MS spectra of the deuterated compounds, were obtained. Accurate mass measurements helped elucidate the structures of smaller fragment ions. Low-energy collision-induced decomposition (CID) tandem mass spectrometry of lexitropsins with electrospray ionization has proven to be a good method for the structural characterization and identification of this class of compounds. Main fragmentation pathways occur by cleavage of the peptide bond followed by the elimination of the substituted pyrrole ring, and their elucidation will facilitate structural characterization of new lexitropsins.

Abstract
A series of meso-5,10,15-tris(N-methyl-4-pyridiniumyl)-20-(4-alkylamidophen yl) porphyrins were synthesized by derivatizing the amino group on the phenyl ring with the following hydrophobic groups: -C(O)C7F15, -C(O)CH=CH2, C(O)CH3, -C(O)C7H15, and -C(O)C15H31. The cationic tris-pyridiumyl porphyrin core serves as a DNA binding motif and a photosensitizer to photomodify DNA molecules. The changes of the UV-Vis absorption spectra during the titration of these porphyrins with calf thymus DNA revealed a large bathochromic shift (up to 14 nm) and a hypochromicity (up to 55%) of the porphyrins Soret bands, usually considered as proof of porphyrin intercalation into DNA. Association constants (K) calculated according to the McGhee and von Hippel model, were in the range of 10(6)-10(7) M(-1). An increase in hydrophobicity of the substituents at the 20-meso-position produced higher binding affinity. These porphyrins caused photomodification of the supercoiled plasmid DNA when a green laser beam at 532 nm was applied. Those with higher surface activity acted more efficiently as DNA photomodifiers. The porphyrin with a perfluorinated alkyl chain (-COC7F15) at the meso-20-position inhibited the growth of gram-positive bacteria (S. aureus, or S. epidermidis). Other porphyrins exhibited moderate activity against both gram-negative and gram-positive organisms.
