While all previous editions have taken place in Timisoara, this year the event has been organized at the „Babes-Bolyai” University in Cluj-Napoca, Romania. This series of symposia was initiated in 1993 by the „Working Group for Metal Research in Biological Systems”, founded by Timisoara researchers in 1979. Past editions have allowed for inter-disciplinary interaction between researchers from various parts of the world, interested in the importance of metals for various aspects of our life. We thank this year’s participants for their valuable contributions, and look forward for even more fruitful discussions during the future editions of this symposium. THE ORGANIZING COMMITTEE Acad.

BECK-SICKINGER,b and Evamarie HEY-HAWKINSa,* a Universität Leipzig, Institute of Inorganic Chemistry, Johannisallee 29, D-04103 Leipzig, Germany, fax: +49-341-9739319; phone: +49-341-9736151; email: [email protected] leipzig.de b Universität Leipzig, Institute of Biochemistry, Brüderstraße 34, D-04103 Leipzig, Germany Abstract High and selective accumulation in tumor cells is an important requirement for a BNCT agent. Increasing the tumor selectivity of BNCT agents may be possible by the use of carbaborane-containing bis-phosphonates and incorporation of carbabo- rane-containing amino acids into breast cancer selective neuropeptide Y derivatives. Keywords: BNCT, carbaboranes, phosphonates, tumor selectivity INTRODUCTION To date, the treatment of malignant tumors is always accompanied by ex- tremely negative side effects. One potentially useful approach for selective destruc- tion of tumor cells is boron neutron capture therapy (BNCT), a powerful form of radio- therapy involving preferential incorporation of 10B-containing compounds into tumor cells, followed by irradiation of the tumor with thermal neutrons. The high-energy fis- sion products which are formed on absorption of a neutron allow selective destruction of the tumor cells without affecting the surrounding healthy tissue. High and selective accumulation in tumor cells is one important requirement for a BNCT agent.1 For successful treatment, a concentration of 30 µg 10B per gram tumor must be achieved. The main problem to date is the availability of boron compounds which exhibit the necessary high selectivity, water solubility, and low toxicity in high concentrations.2 The synthesis of and bioactivity studies on the first phosphorus-containing bo- ron cluster compounds bearing phosphate and pyrophosphate moieties were re- ported by Kaczmarczyk and Bechtold in 1975.3 However, these compounds turned out to be highly toxic. Interestingly, some simple carbaboranyl bis-phosphonates ex- hibit high tumor selectivity and can be used in the treatment of calcifying tumors.4 Oligomeric phosphate diesters which contain closo- or nido-carbaboranes show high accumulation in tumor tissue in BALB/c mice bearing EMT6 tumors.5 However, com- prehensive biological assessments of boron-containing phosphonates as potential tumor-targeting agents in BNCT are still rare.6 We have therefore devised efficient syntheses for novel boron compounds which provide a combined tumor-targeting system: The use of phosphonato groups as phosphate mimics and galactosyl groups for binding to lectins at the surface of a tumor cell.7 Transformation from a normal to a malignant breast cell is accompanied by overexpression of the Y1 receptor.8 Beck-Sickinger and co-workers developed a modified neuropeptide Y derivative featuring high affinity for the Y1 receptor.9 There- „Metal Elements in Environment, Medicine and Biology”, Tome IX, pp. 3 - 10, Cluj University Press, „Babeş-Bolyai” University, Cluj-Napoca, 2009 Proc. of 9th Int. Symp. of Roumanian Academy - Branch Cluj-Napoca and Branch Timişoara, 2009, October 16-17, Cluj-Napoca, Roumania 4 fore, we synthesized carbaborane-containing amino acids for incorporation in neu- ropeptide Y to selectively target breast cancer cells. RESULTS AND DISCUSSION The synthesis of sugar-containing carbaboranyl bis-phosphonates was at- tempted starting from carbaboranyl bis(chlorophosphonates) and a protected sugar (with one hydroxyl group still available). Thus, carbaboranyl bis(chlorophos-phonate) 2 was obtained from 1 by chlorination with sulfuryl chloride (Scheme 1).10 Scheme 1: Synthesis of 2 However, we were unable to convert compound 2 to the target compound by reaction with 1,2:5,6-di-O-isopropylidene-α-D-glucofuranose (3) under different reac- tion conditions; in all cases, only decomposition was observed (Scheme 2). Scheme 2: Reaction of 2 with the sugar derivative 3 led to decomposition As phosphorus(V) sub-stituents on ortho- carbaborane exhibit only low reactivity, more reactive phosphorus(III) deriva-tives were em- ployed. However, no reaction occurred between the dialkylamidohalophospho-nito-substituted ortho-carbabo-ranes 1,2-{P(NR )X} C B H (R 2 2 2 10 10 B = Me, iPr, X = Cl, Br) and isopropylidene- protected galactose 5.
