Abstract
Carboranyl-containing chlorins have emerged as promising dual sensitizers for use in both photodynamic therapy (PDT) and boron neutron capture therapy (BNCT), by virtue of their known tumor affinity, low cytotoxicity in dark conditions, and their strong absorptions in the red region of the optical spectrum. Tetrakis(p-carboranylthio-tetrafluorophenyl)chlorin (TPFC) is a new synthetic carboranyl-containing chlorin of high boron content (24% by weight). To evaluate TPFC's applicability as sensitizer for both PDT and BNCT, we performed an in vitro and in vivo study using F98 rat glioma cells and F98 rat glioma-bearing brain tumor models. For the in vivo BNCT study, we used boronophenylalanine (BPA), which is currently used in clinical BNCT studies, via intravenous administration (i.v.) and/or used TPFC via convection-enhanced delivery (CED), a method for local drug infusion directly into the brain. In the in vitro PDT study, the cell surviving fraction following laser irradiation (9J/cm2) was 0.035 whereas in the in vitro BNCT study, the cell surviving fraction following neutron irradiation (thermal neutron=1.73×1012 n/cm2) was 0.04. In the in vivo BNCT study, the median survival time following concomitant administration of BPA (i.v.) and TPFC (CED) was 42days (95% confidence interval; 37-43days). © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

Abstract
A series of BF2 complexes of hydrazine-Schiff base linked bispyrrole have been prepared from a simple two-step reaction from commercially available substances and are highly fluorescent in solution, film, and solid states with larger Stokes shift and excellent photostabilities comparable or even super to those of their BODIPY analogues. These resultant fluorescent dyes are highly susceptible to the postfunctionalization, as demonstrated in this work via the Knoevenagel condensation to introducing functionalities or tether groups to the chromophore.

Abstract
Two porphyrins of high boron content (OCP and HCP–PEG) were prepared in high yields from the reaction of the corresponding tri- and tetra-(dihydroxyphenyl)porphyrins with zwitterionic cobaltabisdicarbollide [3,3′-Co(8-C4H8O2-1,2-C2B9H10)(1′,2′-C2B9H11)] . Both porphyrins were found to have low cytotoxicity toward human HEp2 cells, and to localize subcellularly mainly in the cell lysosomes. Animal toxicity investigations using male and female BALB/c mice also revealed low toxicity for both compounds. The determined maximum tolerated dose (MTD) for these boronated porphyrins administered intraperitoneally were 160 mg/kg for OCP and 320 mg/kg for HCP–PEG. Our studies warrant further development of these porphyrins of high boron content, and in particular of HCP–PEG, as boron delivery vehicles for BNCT.

Abstract
Background and Purpose: Boron Neutron Capture Therapy (BNCT) is a binary cancer treatment that exploits the short range particles released from a nuclear fission reaction involving the non-radioactive 10 B nucleus and low-energy neutrons for the destruction of tumor cells. In this perspective, porphyrins and phthalocyanines can represent a vehicle for the transport of significant amounts of boron to the neoplastic lesion. Material and Methods: B16F1 melanotic melanoma subcutaneously transplanted in C57/BL6 mice has been used as an in vivo model. Pharmacokinetic studies were performed by intratumoral and intravenous injection of a meso-substituted porphyrin containing 36 B atoms per molecule ( H 2 TCP ) and the distribution of H 2 TCP in the tumor was assessed by fluorescence microscopy analysis. The tumor-bearing mice were exposed to the radiation field for 20 min at a reactor power of 5 kW. Results: At 0.5 h after intratumoral administration or at 24 h after intravenous injection, the amount of 10 B in the tumor was found to be about 60 ppm and about 6 ppm, respectively. In spite of the different amounts of 10 B in the tumor at the time of irradiation, a very similar delay in tumor growth (5-6 days) was induced by neutron irradiation in the two groups of injected mice with respect to control mice. Conclusions: Our results demonstrate that a suitable boron-loaded porphyrin displays a significant affinity for subcutaneous tumors, and upon activation by thermal neutrons, can promote an important response even in a fairly aggressive and generally radioresistant tumor such as melanotic melanoma.

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.
