Abstract
With the development of photodynamic therapy (PDT), remarkable studies have been conducted to generate photosensitisers (PSs), especially porphyrin PSs. A variety of chemical modifications of the porphyrin skeleton have been introduced to improve cellular delivery, stability, and selectivity for cancerous tissues. This review aims to highlight the developments in porphyrin-based structural modifications, with a specific emphasis on the role of PDT in anticancer treatment and the design of PSs to achieve a synergistic effect on multiple targets.

Abstract
Eosin B (EoB) and eosin Y (EoY), two xanthene dye derivatives with photosensitizing ability were prepared in high purity through an improved synthetic route. The dyes were grafted to a 6-monoamino-β-cyclodextrin scaffold under mild reaction conditions through a stable amide linkage using the coupling agent 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride. The molecular conjugates, well soluble in aqueous medium, were extensively characterized by 1D and 2D NMR spectroscopy and mass spectrometry. Preliminary spectroscopic investigations showed that the β-cyclodextrin–EoY conjugate retains both the fluorescence properties and the capability to photogenerate singlet oxygen of the unbound chromophore. In contrast, the corresponding β-cyclodextrin–EoB conjugate did not show either relevant emission or photosensitizing activity probably due to aggregation in aqueous medium, which precludes any response to light excitation.

Abstract
Covalently linked porphyrin/β-cyclodextrin derivatives have been synthesized by reaction between 5,10,15-tris-{p-[9-methoxy-tris-(ethyleneoxy)-phenyl]}-20-(p-hydroxyphenyl)-porphyrin, β-cyclodextrin-6-alcoholate and di-brominated aliphatic chains of different length, and characterized by MALDI-TOF mass spectrometry, 1H NMR and UV-vis spectroscopy. As a function of chain length, these compounds exhibit different degrees of water solubility, becoming higher with increasing chain length. The lack of self-assemblies between porphyrins and β-cyclodextrins (which renders the two sub-units completely free to perform their activities) and their water solubility, make these compounds excellent candidates in fields like drug-delivery or photodynamic therapy.

Abstract
In this study, 5,10,15-tri[p(9-methoxy-triethyleneoxy)phenyl]-20-[p-phenylisophthalate-β-cyclodextrin]porphyrin, a compound containing a porphyrin and a β-cyclodextrin unit covalently linked by means of an isophthalic bridge, was synthesized and characterized by NMR, MALDI-TOF mass spectrometry and UV-vis and circular dichroism spectroscopies. This porphyrin/β-cyclodextrin system, with the porphyrin unit connected to the lower rim (OH-2) of the cyclodextrin structure, is water-soluble and no evidence of a self-assembly arrangement between the porphyrin and cyclodextrin units appears. In this way, the β-cyclodextrin cavities remain free, retaining their potential ability of drug-delivery, with the spectroscopic advantage induced by the high absorbance of the porphyrin unit. Furthermore, the porphyrin unit, interacting with the guest and acting as a lid, could have a role in the controlled release process of the drug.

Abstract
Water-soluble porphyrins tend to form self-aggregates under certain conditions. The structure of the self-aggregate (H-type dimer, H-type higher aggregate, or J-aggregate) sensitively depends on the structure of the peripheral substituents at the meso-positions of the porphyrin. Water-soluble porphyrins also form relatively stable π-stacked complexes with various aromatics. Polar effects are important in complexation of anionic porphyrins with anthraquinonesulfonates. The results suggest that the main attractive interaction for formation of π-stacked complexes of water-soluble porphyrins is the σ-π interaction as claimed by Hunter and Sanders. Meanwhile, the aryl groups at the meso-positions of the water-soluble porphyrins are included by per-O-methylated β-cyclodextrin through van der Waals interactions to form extremely stable 1:2 complexes (porphyrin:cyclodextrin). Such a character of the water-soluble porphyrins can be applied to convenient preparation of supramolecular hetero-porphyrin arrays.

Abstract
A new cyclodextrin-based carrier for active targeting of low soluble and degradable drugs has been synthesized and characterized. Beta-cyclodextrins were first reacted with excess hexamethylene diisocyanate and the resulting CD-(C6-NCO)5 derivative was reacted with 700 Da diamino-PEG to yield CD-(C6-PEG-NH2)5. About one out of five free amino groups of PEG were functionalised with folic acid (FA) as a tumour targeting moiety. The chemical structures of the intermediates as well as the final product, CD-(C6-PEG)5-FA, were characterized by 1H and 13C NMR, reverse phase and gel permeation chromatography, and UV-Vis spectroscopy. After modification, the haemolytic activity of beta-cyclodextrins decreased by about 70%. In the presence of the new carrier, the beta-estradiol solubility increased by more than 300 fold and the chlorambucil degradation rate decreased by 50-60%. CD-(C6-PEG)5-FA formed an inclusion complex with curcumin displaying an association constant of 954,732 M(-1). The new carrier increased the curcumin solubility by about 3200 fold as compared to native beta-cyclodextrins and reduced its degradation rate at pH 6.5 and 7.2 by 10 and 45 fold, respectively. FA receptor-overexpressing human nasopharyngeal tumour KB cell lines and non-folic acid receptor-expressing human breast cancer MCF7 cells were used to evaluate the targeting properties of the new drug delivery system. The in vitro studies demonstrate that the new carrier possesses potential selectivity for the folate receptor-overexpressing tumour cells as ED50 values of 52 microM, 58 microM and 21 microM were obtained with curcumin-loaded CD-(C6-PEG-NH2)5, curcumin in foetal serum medium and CD-(C6-PEG)5-FA, respectively.

Abstract
Cyclodextrin-based aggregates have been widely investigated with microscopies such as STM, AFM, SEM, TEM, and fluorescent microscopy to obtain the direct morphology and structure of samples. In the present review, we discuss various types of cyclodextrin aggregates, that is, native and modified cyclodextrins, inclusion complexes and their aggregates of cyclodextrins, cyclodextrin rotaxanes and polyrotaxanes, cyclodextrin nanotubes and their secondary assembly, and other high-order aggregates of cyclodextrins. Especially, we focus on the use of microscopy to characterize above aggregates. The application of modern microscopy tools promotes the investigation on cyclodextrins.

Abstract
In the present study we investigated the photosensitizing properties of two novel mono- and bis-cyclodextrin tetrakis (pentafluorophenyl) porphyrin derivatives in several tumor cell lines and in BALB/c mice bearing subcutaneously transplanted syngeneic mouse mammary carcinoma 4T1. Both studied sensitizers were localized mainly in lysosomes and were found to induce cell death by triggering apoptosis in human leukemic cells HL-60. In 4T1 and other cell lines both apoptotic and necrotic modes of cell death occurred depending on drug and light doses. Mono-cyclodextrin porphyrin derivative P(beta-CD)1 exhibited stronger in vitro phototoxic effect than bis-cyclodextrin derivative P(beta-CD)2. However, in vivo P(beta-CD)2 displayed faster tumor uptake with maximal accumulation 6 h after application, leading to complete and prolonged elimination of subcutaneous tumors within 3 days after irradiation (100 J cm(-2)). In contrast, P(beta-CD)1 uptake was slower (48 h) and the reduction of tumor mass was only transient, reaching the maximum at the 12 h interval when a favorable tumor-to-skin ratio appeared. Thus, P(beta-CD)2 represents a new photosensitizing drug displaying fast and selective tumor uptake, strong antitumor activity and fast elimination from the body.

Abstract
The interaction between the anionic 5,10,15,20-tetrakis(4-sulfonatophenyl)-21H,23H-porphyrin (TPPS) and cationic vesicles formed by heptakis(2-omega-amino-O-oligo(ethylene oxide)-6-hexylthio)-beta-cyclodextrin (SC6CDNH2) has been investigated in detail through a combination of elastic light scattering (ELS), quasi-elastic light scattering (QELS), zeta potential measurements, and time-resolved fluorescence anisotropy. ELS experiments provided the first structural characterization of these cationic vesicles both in the absence and in the presence of TPPS porphyrin, modeling the system as a spherical particle described by a single thin shell form factor. The structure of mixed hetero-aggregates is modulated by charge and size of the two components as function of different porphyrin/cyclodextrin (CD) molar ratios. At the limiting molar ratio studied, the absolute value of zeta potential (/zeta/ = 12.5 mV) seems to be a reference value for the formation of stable colloidal CD vesicular aggregates at thermodynamic equilibrium. New insights on the structure of these heterotopic colloids have been obtained by analysis of rotational correlation times at different molar ratios exploiting time-resolved fluorescence anisotropy experiments. At high porphyrin loads, the anisotropy decays behave as monoexponentials and the rotational correlation times (1-2 ns) together with the r(0) values close to zero suggest the presence of small amounts of TPPS embedded in a hydrophobic environment either in monomeric or in aggregated form. At the lower porphyrin/CD molar ratios, the anisotropy decays exhibit a double-exponential behavior showing a predominant component with a slow rotational correlation time (20-25 ns) and limiting anisotropy values of approximately 0.15. This component has been assigned to molecules that are more stabilized onto the CD vesicles, that is, porphyrins embedded into the oligo-ethylene "wall" of the CD vesicles. Scanning near-field optical microscopy of the samples evaporated on glass surfaces gave further insights on the morphology and optical properties of these systems, confirming the embedding of TPPS on the vesicles and evidencing the role of the solvent.

Abstract
The tumor targeting properties of a new drug carrier synthesized by bioconjugation of folic acid (FA) to beta-cyclodextrins through a poly(ethylene glycol) (PEG) spacer (CD-PEG-FA) were investigated. Surface plasmon resonance demonstrated that CD-PEG-FA specifically interacts with immobilized folate binding protein (FBP) while the naked beta-cyclodextrins do not display any specific interaction. In vitro studies demonstrated that CD-PEG-FA was devoid of cell toxicity. [(3)H]-folic acid/CD-PEG-FA competition binding investigations performed with folate receptor overexpressing human epidermal carcinoma KB cells showed that CD-PEG-FA had about 14 times lower tumor cell binding capacity than free folic acid. The carrier cell trafficking properties were investigated using rhodamine-B as fluorescent probe, which possesses 3000 and 4580 M(-)(1) inclusion constants for CD-PEG-FA and beta-cyclodextrins, respectively. Cell-associated fluorescence measurements showed that CD-PEG-FA does not promote the rhodamine-B uptake into non-folate receptor expressing human lung carcinoma MCF7 cells while 19% higher accumulation in KB cells was found with respect to rhodamine-B loaded beta-cyclodextrins. Confocal laser scanning microscopy indicated the presence of cytosolic red fluorescent spots after 2 h of incubation of KB cells with rhodamine-B included CD-PEG-FA. The fluorescent dye resided primarily in small spots, namely, endosomes and multivesicular bodies. At 1 h after pulsed incubation, wider red fluorescent cellular structures appeared as a fusion of previous structures.

Abstract
A new methodology for preparing heteroporphyrin arrays in aqueous solution has been presented. The present method is based on the extremely strong ability of heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TMe-beta-CD) to include 5,10,15,20-tetrakis(p-substituted-phenyl)porphyrins (Por) affording trans-type 1:2 complexes of the porphyrins and TMe-beta-CD. Two different Por-per-O-methylated beta-CD (per-Me-beta-CD) conjugates were synthesized. Conjugate 2 was prepared by an S(N)2 reaction of 5,10,15,20-tetrakis(p-hydroxyphenyl)porphyrin and per-O-methylated beta-cyclodextrin having one primary OTs group. Four per-Me-beta-CD moieties are attached to the meso positions of 2. Conjugate 3, synthesized from 5-(p-hydroxyphenyl)-10,15,20-tris(3,5-dicarboxyphenyl)porphyrin and monotosylated per-O-methylated beta-cyclodextrin, has one per-Me-beta-CD moiety at the periphery of the porphyrin. Conjugate 2 yields a stable 1:4 complex with the zinc complex of 5-phenyl-10,15,20-tris(3,5-dicarboxyphenyl)porphyrin (8) in the dissociated form. In this system, the energy transfer from photoexcited Zn-8 to free base 2 occurs with 85% efficiency. Conjugate 3 forms a very stable 1:1 complex with Zn-8 (K = (7.0 +/- 0.3) x 10(5) dm(3) mol(-1)) with an energy transfer efficiency (93%) larger than that obtained in the case of 2. The structure of the 3-Zn-8 complex, which can account for the efficient energy transfer, was deduced from (1)H NMR spectroscopy. Intramolecular fluorescence quenching of 2 and 3 by Fe(III)-8 also occurred through an electron-transfer process as the main quenching mechanism. The present method is a very simple and convenient means to construct various heteroporphyrin arrays in aqueous solution.
