Abstract
Radiotherapy is a well-established cytotoxic therapy for local solid cancers, utilizing high-energy ionizing radiation to destroy cancer cells. However, this method has several limitations, including low radiation energy deposition, severe damage to surrounding normal cells, and high tumor resistance to radiation. Among various radiotherapy methods, boron neutron capture therapy (BNCT) has emerged as a principal approach to improve the therapeutic ratio of malignancies and reduce lethality to surrounding normal tissue, but it remains deficient in terms of insufficient boron accumulation as well as short retention time, which limits the curative effect. Recently, a series of radiosensitizers that can selectively accumulate in specific organelles of cancer cells have been developed to precisely target radiotherapy, thereby reducing side effects of normal tissue damage, overcoming radioresistance, and improving radiosensitivity. In this review, we mainly focus on the field of nanomedicine-based cancer radiotherapy and discuss the organelle-targeted radiosensitizers, specifically including nucleus, mitochondria, endoplasmic reticulum and lysosomes. Furthermore, the organelle-targeted boron carriers used in BNCT are particularly presented. Through demonstrating recent developments in organelle-targeted radiosensitization, we hope to provide insight into the design of organelle-targeted radiosensitizers for clinical cancer treatment.

Abstract
Background To overcome proton therapy limitations [low linear energy transfer (LET) radiation with a relative biological effectiveness (RBE) typically ranging from 1.1 to 1.2], radiosensitization techniques can be employed to increase the radiosensitivity of tumor cells and improve the effectiveness of radiation therapy. In this study, we suggest using a boron-based medium to overcome the biological limitations of proton therapy. By inducing the hydrogen-boron fusion reaction (p + 11B → 3α) of incident protons and capturing thermal neutrons [10B + n → 7Li3+ (0.84 MeV) + 4He2+ (1.47 MeV) + γ (0.477 MeV)], high LET α particles can be released. We propose a "ternary" radiotherapy model to enhance the biological effect of proton therapy. Methods Using Monte Carlo simulation, the possibility of interacting low-energy proton beams with 11B and thermal neutrons with 10B to produce α particles with higher RBE to enhance the biological effect of proton radiotherapy were investigated. And the number and location of α particles and thermal neutrons produced by the interaction of protons with natural boron had also been studied. Results Under the basic principle of the "ternary" radiotherapy model, comparative analyses of neutrons and α particles produced by proton beams of different energies incident on the phantoms, which were composed of boron isotopes of different concentrations in proportion to the phantoms, have shown that the α particle yield decreased with decreasing boron doping concentration, whereas the neutron yield increased with decreasing boron doping concentration. The distribution of thermal neutrons and α particles in the longitudinal direction of the proton beam were also studied, and it was found that the number of α particles produced was high at high boron concentrations, and the locations of α and thermal neutrons were close to the treatment target. Conclusions The proton therapy ternary model is theoretically feasible from the perspective of mathematical analysis and Monte Carlo simulation experiments.

Abstract
Boron neutron capture therapy (BNCT) is a binary cancer treatment that involves the irradiation of 10B-containing tumors with low-energy neutrons (thermal or epithermal). The alpha particles and recoiling Li nuclei that are produced in the 10B-capture nuclear reaction are high-linear-energy transfer particles that destroy boron-loaded tumor cells; therefore, BNCT has the potential to be a localized therapeutic modality. Two boron-delivery agents have been used in clinical trials of BNCT in patients with malignant brain tumors, cutaneous melanoma, or recurrent tumors of the head and neck region, demonstrating the potential of BNCT in the treatment of difficult cancers. A variety of potentially highly effective boron-delivery agents have been synthesized in the past four decades and tested in cells and animal models. These include boron-containing nucleosides, peptides, proteins, polyamines, porphyrins, liposomes, monoclonal antibodies, and nanoparticles of various types. The most promising agents are multi-functional boronated molecules and nanoparticles functionalized with tumor cell-targeting moieties that increase their tumor selectivity and contain a radiolabel or fluorophore to allow quantification of 10B-biodistribution and treatment planning. This review discusses multi-functional boron agents reported in the last decade, but their full potential can only be ascertained after their evaluation in BNCT clinical trials.

Abstract
An efficient approach for the preparation of 3,5-dicarborane-substituted BODIPY conjugates was developed via the functionalization of 3,5-dibromo-8-pentafluorophenyl-BODIPY with neutral and anionic carborane S-nucleophiles. It was found that 3,5-dicarborane-substituted BODIPYs could be easily modified with a third carborane cluster using SNAr substitution reactions of the para-fluorine atom in the meso-pentafluorophenyl BODIPY substituent with the corresponding carborane S-nucleophile affording boron-enriched BODIPYs in good yields. The influence of bromine atom substitution with carborane moieties on the position of absorption and fluorescence bands and the fluorescence quantum yields of the prepared BODIPYs were analyzed. The crystal structures of BODIPYs 4 and 8 were investigated. Density functional theory methods (DFT wb97xd/6-31G* and wb97xd/lanl2dz) were performed to study the geometrical structures, electronic characteristics, the highest occupied and the lowest unoccupied molecular orbitals (HOMOs and LUMOs) and other chemical descriptors of the synthesized compounds.

Abstract
This proceeding article compiles current research on the development of boron delivery drugs for boron neutron capture therapy that was presented and discussed at the National Cancer Institute (NCI) Workshop on Neutron Capture Therapy that took place on April 20-22, 2022. The most used boron sources are icosahedral boron clusters attached to peptides, proteins (such as albumin), porphyrin derivatives, dendrimers, polymers, and nanoparticles, or encapsulated into liposomes. These boron clusters and/or carriers can be labeled with contrast agents allowing for the use of imaging techniques, such as PET, SPECT, and fluorescence, that enable quantification of tumor-localized boron and their use as theranostic agents.

Abstract
Boron dipyrromethene (BODIPY) dyes bearing a pyridyl moiety have been used as metal ion sensors, pH sensors, fluorescence probes, and as sensitizers for phototherapy. A comparative study of the properties of the three structural isomers of meso-pyridyl-BODIPYs, their 2,6-dichloro derivatives, and their corresponding methylated cationic pyridinium-BODIPYs was conducted using spectroscopic and electrochemical methods, X-ray analyses, and TD-DFT calculations. Among the neutral derivatives, the 3Py and 4Py isomers showed the highest relative fluorescence quantum yields in organic solvents, which were further enhanced 2-4-fold via the introduction of two chlorines at the 2,6-positions. Among the cationic derivatives, the 2catPy showed the highest relative fluorescence quantum yield in organic solvents, which was further enhanced by the use of a bulky counter anion (PF6-). In water, the quantum yields were greatly reduced for all three isomers but were shown to be enhanced upon introduction of 2,6-dichloro groups. Our results indicate that 2,6-dichloro-meso-(2- and 3-pyridinium)-BODIPYs are the most promising for sensing applications. Furthermore, all pyridinium BODIPYs are highly water-soluble and display low cytotoxicity towards human HEp2 cells.

Abstract
![]()
Glioblastoma (GBM) is a highly malignant
brain tumor characterized
by a heterogeneous population of genetically unstable and highly infiltrative
cells that are resistant to chemotherapy. Although substantial efforts
have been invested in the field of anti-GBM drug discovery in the
past decade, success has primarily been confined to the preclinical
level, and clinical studies have often been hampered due to efficacy-,
selectivity-, or physicochemical property-related issues. Thus, expansion
of the list of molecular targets coupled with a pragmatic design of
new small-molecule inhibitors with central nervous system (CNS)-penetrating
ability is required to steer the wheels of anti-GBM drug discovery
endeavors. This Perspective presents various aspects of drug discovery
(challenges in GBM drug discovery and delivery, therapeutic targets,
and agents under clinical investigation). The comprehensively covered
sections include the recent medicinal chemistry campaigns embarked
upon to validate the potential of numerous enzymes/proteins/receptors
as therapeutic targets in GBM.

Abstract
On the basis of the boron neutron capture therapy (BNCT) modality, we have designed and synthesized a zinc gallate (ZnGa2O4)-based nanoformulation for developing an innovative theranostic approach for cancer treatment. Initially, the (ZnGa1.995Cr0.005O4 or ZnGa2O4:(0.5%)Cr persistent luminescence nanoparticles (PLNPs) embedded on silica matrix were synthesized. Their surface functionalization was performed using organic synthesis strategies to attach the amine functional moieties which were further coupled with poly(vicinal diol). These diols were helpful for conjugation with 10B(OH)3, which subsequently served to couple with an in-house-synthesized variant of pH-(low)-insertion peptide (pHLIP) finally giving a tumor-targeting nanoformulation. Most importantly, the polymeric diols helped in conjugation of a substantial number of 10B to provide the therapeutic dose required for effective BNCT. This nanoformulation internalized substantially (∼80%) to WEHI-164 cancer cells within 6 h. Tumor homing studies indicated that the accumulation of this formulation at the acidic tumor site was within 2 h. The in vitro evaluation of the formulation against WEHI-164 cancer cells followed by neutron irradiation revealed its potent cytotoxicity with IC50 ∼ 25 μM. In the case of studies on animal models, the melanoma-induced C57BL/6 and fibrosarcoma-induced BALB/c mice were treated with formulations through intratumoral and intravenous injections, respectively, followed by neutron irradiation, leading to a significant killing of the cancer cells, which was evidenced by a reduction in tumor volume (75-80%) as compared with a control tumor. Furthermore, the histopathological studies confirmed a damaging effect only on tumor cells, while there was no sign of damage to the vital organs in treated mice as well as in controls.

Abstract
Carborane are widely applied in boron neutron capture therapy (BNCT) field, but it is difficult to perform biocompatibility with cells due to its own water solubility differences, so how to solve the water solubility problem has always been the focus of research. A simple, inexpensive and effective method was used to study the synthesis of nido-carborane azaspirodecanium poly(carboxybetaine methacrylate) by one-pot cyclization of nido-carborane azaspirodecanium under the synergistic effect of inorganic bases and conventional organic solvents. Its characterization is mainly to use 1H-NMR nuclear magnetic resonance spectrum and infrared spectroscopy to determine the characteristic peak and range of borane. Through transmission electron microscope (TEM), it can be observed that the white nanoparticles, namely carborane, are completely contained by polymer ions, which not only increases the surface area but also the concentration of boron uptake in the cell is 100 times that of borono-phenylalanine (BPA). Based on the successful synthesis of N-CB5-4 and N-CB6-5 without harsh conditions, a feasibility point of view was put forward, namely, super water-soluble carborane polymer.

Appl Radiat Isot 2021; 170:109596.

Abstract
Recently it has been suggested that the presence of boron-11 during proton therapy leads to a significant dose increasement in the BUR. Three high-LET alpha particles with an average energy of 4 MeV are generated at the point of interaction between proton and boron-11. Nevertheless, the cross-section of p+B11→3α interaction is negligible and dose increasement is unlikely. The purpose of this study is dose evaluation of the proton therapy with and without the boron-11. All simulations were performed using MCNPX 2.6.0 code at the Snyder head phantom. At the elderly stage, the range of Bragg-peaks was adapted to the tumor volume, with and without boron-11. Then, the different concentrations of boron-11 were assumed including 65,500,103,105,2.5×105 and 5×105ppm in the tumor region. To investigate the maximum effectiveness of PBFT (proton boron fusion therapy), the entire tumor was assumed full of boron-11, and the dose components were calculated. Consequently, In the best case, the maximum dose amplification was less than 5%, in which the entire tumor was assumed full boron-11. The total number of alpha particles generated from p+B11→3α interaction is negligible. As well as the presence of boron-11 during the proton therapy makes that the Bragg-peaks happen in greater depth. Hence, from the Monte Carlo standpoint, the effectiveness of the proton boron fusion therapy is not related to the alpha particles because the dose component of alpha particles is negligible.

Abstract
Boron neutron capture therapy (BNCT) is a radiotherapeutic modality based on the nuclear capture of slow neutrons by stable 10B atoms followed by charged particle emission that inducing extensive damage on a very localized level (<10 μm). To be efficient, a sufficient amount of 10B should accumulate in the tumor area while being almost cleared from the normal surroundings. A water-soluble aza-boron-dipyrromethene dyes (BODIPY) fluorophore was reported to strongly accumulate in the tumor area with high and BNCT compatible Tumor/Healthy Tissue ratios. The clinically used 10B-BSH (sodium borocaptate) was coupled to the water-soluble aza-BODIPY platform for enhanced 10B-BSH tumor vectorization. We demonstrated a strong uptake of the compound in tumor cells and determined its biodistribution in mice-bearing tumors. A model of chorioallantoic membrane-bearing glioblastoma xenograft was developed to evidence the BNCT potential of such compound, by subjecting it to slow neutrons. We demonstrated the tumor accumulation of the compound in real-time using optical imaging and ex vivo using elemental imaging based on laser-induced breakdown spectroscopy. The tumor growth was significantly reduced as compared to BNCT with 10B-BSH. Altogether, the fluorescent aza-BODIPY/10B-BSH compound is able to vectorize and image the 10B-BSH in the tumor area, increasing its theranostic potential for efficient approach of BNCT.

Abstract
The role of autophagy in cancer is often complex, ranging from tumor-promoting to -suppressing effects. In this study, two novel hybrid molecules were designed, containing a ruthenacarborane fragment conjugated with a known modulator of autophagy, namely a quinoline derivative. The complex closo-[3-(η6 -p-cymene)-1-(quinolin-8-yl-acetate)-3,1,2-RuC2 B9 H10 ] (4) showed a dual mode of action against the LN229 (human glioblastoma) cell line, where it inhibited tumor-promoting autophagy, and strongly inhibited cell proliferation, de facto blocking cellular division. These results, together with the tendency to spontaneously form nanoparticles in aqueous solution, make complex 4 a very promising drug candidate for further studies in vivo, for the treatment of autophagy-prone glioblastomas.

Abstract
The potential biomedical applications of the MNPs nanohybrids coated with m-carboranylphosphinate (1-MNPs) as a theranostic biomaterial for cancer therapy were tested. The cellular uptake and toxicity profile of 1-MNPs from culture media by human brain endothelial cells (hCMEC/D3) and glioblastoma multiform A172 cell line were demonstrated. Prior to testing 1-MNPs' in vitro toxicity, studies of colloidal stability of the 1-MNPs' suspension in different culture media and temperatures were carried out. TEM images and chemical titration confirmed that 1-MNPs penetrate into cells. Additionally, to explore 1-MNPs' potential use in Boron Neutron Capture Therapy (BNCT) for treating cancer locally, the presence of the m-carboranyl coordinated with the MNPs core after uptake was proven by XPS and EELS. Importantly, thermal neutrons irradiation in BNCT reduced by 2.5 the number of cultured glioblastoma cells after 1-MNP treatment, and the systemic administration of 1-MNPs in mice was well tolerated with no major signs of toxicity.

Abstract
Through the use of a rhodamine-appended chelate, bpy-Rho, a versatile strategy has been demonstrated to readily form mitochondria-targeting photosensitizers via the incorporation of a variety of luminescent transition-metal systems, M-Rho, such as Re(I), Ir(III), Pt(II), and Rh(III). The emission from the rhodamine singlet excited state and the transition-metal triplet excited state is partially quenched by the depopulation of them into the dark rhodamine triplet excited state. The generation of the triplet excited state of a rhodamine moiety endows the complexes with mitochondria-targeting photosensitizing ability to form singlet oxygen (1O2) for use as a photodynamic therapy (PDT) agent upon visible-light irradiation. The combination of the rhodamine organic dye and luminescent transition-metal centers in such hybrid systems exhibits the synergistic merits for the biological applications, including low dark cytotoxicity, selective tumor cell uptake, high molar absorptivity suitable for low-energy excitation in the visible region, and high photostability. The corresponding in vitro photocytotoxicity and in vivo photo-antitumor efficacy have also been studied to demonstrate the potential PDT application of M-Rho.

Abstract
Boron containing polyhedra (carboranes) are three-dimensional delocalized aromatic systems. These structures have been shown to transport protons through lipid membranes and mitochondria. Conjugation of carboranes to various organic moieties is aimed at obtaining biologically active compounds with novel properties. Taking advantage of 1,2,3-triazoles as the scaffolds valuable in medicinal chemistry, we synthesized 1-(o-carboranylmethyl)-4-pentyl-1,2,3-triazole (c-triazole) and 1-(o-carboranylmethyl)-4-pentyl-1,2,3-triazolium iodide (c-triazolium). Both compounds interacted with model lipid membranes and exhibited a proton carrying activity in planar bilayers and liposomes in a concentration- and pH-dependent manner. Importantly, mechanisms of the protonophoric activity differed; namely, protonation-deprotonation reactions of the triazole and the o-carborane moieties were involved in the transport cycles of c-triazole and c-triazolium, respectively. At micromolar concentrations, c-triazole and c-triazolium stimulated respiration of isolated rat liver mitochondria and depolarized their membrane potential, with c-triazole being more potent. In living K562 (human chronic myelogenous leukemia) cells, both c-triazolium and c-triazole altered the mitochondrial membrane potential as determined by a decreased intracellular accumulation of the potential-dependent dye tetramethylrhodamine ethyl ester. Finally, cell viability testing demonstrated a cytotoxic potency of c-triazolium and, to a lesser extent, of c-triazole against K562 cells, whereas non-malignant fibroblasts were much less sensitive. In all tests, the reference boron-free benzyl-4-pentyl-1,2,3-triazole showed little-to-no effects. These results demonstrated that carboranyltriazoles carry protons across biological membranes, a property potentially important in anticancer drug design.

Abstract
Abstract
For the first time, carborane complexes containing a B(4)–S bond were obtained directly by heating mononuclear Pd-B(4)-bound carborane complexes. A possible mechanism involved in sulfur atom migration is presented in which the leaving group, pyridine, benzyl isocyanide or PPh3, is demonstrated to be the trigger of the reaction process. In this work, efficient routes are developed through one-pot reactions to prepare B(4)-S carborane derivatives.

Abstract
In this work, we reported the geometrical structures, electronic and spectral properties of the carborane-containing BODIPYs complexes using the density functional theory calculations. In two structures, the calculated main bond lengths and bond angels of structural framework are consistent with X-ray experiment, and the two BODIPYs complexes are thermodynamically and kinetically stable. The strongest DOS band is mainly dominated by the BB and BH σ-bonds of carborane fragment, whereas the π-type MOs on the pyrromethene fragment contribute to the high-energy DOS bands. Analysis of the AdNDP chemical bonding indicates that the carborane cage can be stabilized by eleven delocalized 3c2e and two delocalized 4c2e σ-bonds, while the pyrromethene fragment corresponds to five delocalized 3c2e π-bonds. In addition, the main characteristic peaks of the two simulated IR spectra for the BODIPYs complexes are properly assigned. Hopefully, all these results will be helpful for understanding the electronic structures, and further stimulate the study on the biological and medical applications.

Abstract
Three [(η6-arene)RuC2B9H11] complexes (arene = p-cymene (2), biphenyl (3) and 1-Me-4-COOEt-C6H4 (4)) were synthesised according to modified literature procedures and fully characterised. 2-4 were found to be moderately active against two types of tumour cell lines (HCT116 and MCF7), with IC50 values in the low micromolar range. However, viability of normal, healthy cells (MRC-5 cell line, MLEC and mouse macrophages) was not affected by treatment with 2-4, indicating high selectivity of the metallacarborane complexes towards tumour cell lines, compared to the unselective antitumour agent cisplatin and other potential RuII drugs. Moreover, flow cytometric analysis suggested that 4 induces cell death via a caspase-dependent apoptotic mechanism. DFT calculations of the frontier molecular orbitals showed that the HOMO-LUMO gap in 2-4 is smaller than in the corresponding cyclopentadienyl complexes 2-Cp-4-Cp (e.g. 5.47 (2) vs. 6.31 eV (2-Cp)). In order to assess the stability of 2-4, particularly the ruthenium-dicarbollide bond, energy decomposition analysis (EDA) of 2-4, together with the respective cyclopentadienyl analogues 2-Cp-4-Cp, was performed. EDA suggests that the ruthenium(ii)-dicarbollide bond in the three complexes is mostly ionic and far stronger than the ruthenium(ii)-arene bond.

Abstract
The reported new anilinoquinazoline-icosahedral borane hybrids have been evaluated as glioma targeting for potential use in cancer therapy. Their anti-glioma activity depends on hybrids' lipophilicity; the most powerful compound against glioma cells, a 1,7-closo-derivative, displayed at least 3.3 times higher activity than the parent drug erlotinib. According to the cytotoxic effects on normal glia cells, the hybrids were selective for epidermal growth factor receptor (EGFR)-overexpressed tumor cells. These boron carriers could be used to enrich glioma cancer cells with boron for cancer therapy.

Abstract
Regioselective functionalization of 2,3,5,6,8-pentachloro-BODIPY 1 produced unsymmetric BODIPY 5, bearing an isothiocyanate group suitable for conjugation, in only four steps. The X-ray structure of 5 reveals a nearly planar BODIPY core with aryl dihedral angles in the range 47.4-62.9°. Conjugation of 5 to two EGFR-targeting pegylated peptides, 3PEG-LARLLT (6) and 3PEG-GYHWYGYTPQNVI (7), under mild conditions (30 min at room temperature), afforded BODIPY conjugates 8 and 9 in 50-80% isolated yields. These conjugates showed red-shifted absorption and emission spectra compared with 5, in the near-IR region, and were evaluated as potential fluorescence imaging agents for EGFR overexpressing cells. SPR and docking investigations suggested that conjugate 8 bearing the LARLLT sequence binds to EGFR more effectively than 9 bearing the GYHWYGYTPQNVI peptide, in part due to the lower solubility of 9, and its tendency for aggregation at concentrations above 10 μM. Studies in human carcinoma HEp2 cells overexpressing EGFR demonstrated low dark and photo cytotoxicities for BODIPY 5 and the two peptide conjugates, and remarkably high cellular uptake for both conjugates 8 and 9, up to 90-fold compared with BODIPY 5 after 1 h. Fluorescence imaging studies in HEp2 cells revealed subcellular localization of the BODIPY-peptide conjugates mainly in the Golgi apparatus and the cell lysosomes. The low cytotoxicity of the new conjugates and their remarkably high uptake into EGFR overexpressing cells renders them promising imaging agents for cancers overexpressing EGFR.

Abstract
We report the synthesis and investigation of an unprecedented 8-heteroaryl-fused BODIPY 4. This compound exhibits enhanced π-π stacking in the solid state, unusually large blue-shifts in the absorbance and emission spectra, and higher fluorescence quantum yield than its unfused precursor; DFT calculations suggest a small energy gap for 4 and strong electronic communication between the 8-OPh and the BODIPY core.

Abstract
A series of push-pull BODIPYs bearing multiple electron-donating and electron-acceptor groups were synthesized regioselectively from 2,3,5,6,8-pentachloro-BODIPY, and characterized by NMR spectroscopy, HRMS, and X-ray crystallography. The influence of the push-pull substituents on the spectroscopic and electrochemical properties of BODIPYs was investigated. Bathochromic shifts were observed for both absorbance (up to 37 nm) and emission (up to 60 nm) in different solvents upon introduction of the push-pull moieties. DFT calculations, consistent with the spectroscopic and cyclic voltammetry studies, show decreased HOMO-LUMO energy gaps upon the installation of the push-pull moieties. BODIPY 7 bearing thienyl groups on the 2 and 6 positions showed the largest λmax for both absorption (635-653 nm) and emission (706-707 nm), but also the lowest fluorescence quantum yields. All BODIPYs were nontoxic in the dark (IC50 > 200 μM) and showed low phototoxicity (IC50 > 100 μM, 1.5 J/cm2) toward human HEp2 cells. Despite the relatively low fluorescence quantum yields, the push-pull BODIPYS were effective for cell imaging, readily accumulating within cells and localizing mainly in the ER and Golgi. Our structure-property studies can guide future design of functionalized BODIPYs for various applications, including bioimaging and in dye-sensitized solar cells.

Abstract
A series of boron-functionalized BODIPY dyes with cyano groups were prepared from their corresponding BF2derivatives using SnCl4/TMSCN at room temperature for 10 min. Replacement of the fluorines by cyano groups reduces the B–N bond lengths, decreases the charge on boron, and causes characteristic [Formula: see text]B NMR chemical shifts. The 4,4[Formula: see text]-dicyano-BODIPYs show significantly enhanced stability to acidic conditions (excess TFA) and, with one exception, enhanced fluorescence quantum yields. Furthermore, the B(CN)2-BODIPYs were non-cytotoxic to HEp2 cells, both in the dark and upon exposure to light (1.5 J/cm[Formula: see text], and rapidly accumulated within cells, localizing mainly in the lysosomes, ER and Golgi.

Abstract
Three perhalogenated BODIPYs (1b-3b), bearing chloro and bromo groups at all carbon positions, were synthesized and characterized. The reactivity of BODIPY 3b was investigated under Stille cross-coupling reactions, and single crystal X-ray analysis was used to confirm the regioselectivity of the reactions. Further substitution at the boron atom produced nona-functionalized BODIPYs 7a,b, which show 676 and 739 nm emissions with 91 and 100 nm Stokes shifts, respectively.

Abstract
ortho-Carborane (1,2-C2B10H12) was found to be a carrier of protons in lipid membranes and mitochondria, suggesting that this dicarborane can reversibly release hydrogen ions and diffuse through the membrane.
