Treatment of the labile precursor complexes cis- or trans-[PtCl(dmf)(NH3)2]OTf (dmf=N,N-dimethylformamide; OTf=trifluoromethanesulfonate) with the monodentate 1-aminoalkyl-1,2-carborane ligands NH2(CH2)nC2B10H11 (n=1,3) afforded the moderately-stable species cis- or trans-[PtCl(NH3)2NH2(CH2)nC2B10H11}]OTf, respectively. The novel complexes are the first examples of platinum(II)-amine derivatives containing

Derivatives of boron cluster compounds of general formula I and their pharmaceutically acceptable salts and solvates, and their specific inhibition effect on the enzyme carbonic anhydrase IX, a protein overexpressed in cancer tissues. Methods of synthesis and the use of the novel derivatives. These inhibitors of human carbonic anhydrase IX can be used as active compounds of pharmaceuticals for diagnostics and/or therapy of cancer diseases.

Herein we describe our recent attempts to target the P2X7 receptor for potential treatment of neurological disorders. This work focusses on different polycycles including carborane, adamantane or cubane, joined by either a cyanoguanidine or an amide linker to phenyl or isoquinoline moieties. We have demonstrated the superiority of the adamantyl moiety over other polycycles in terms of synthetic accessibility and biological (cellular) activity. We have also shown that an amide or cyanoguanidine linker can greatly alter the biological activity of compounds. This SAR study provides important insights into the types of functionality required to target the P2X7 receptor. (C) 2017 Elsevier Ltd. All rights reserved.

The reactivity of the known amino carboranes 1-H2NCH2-1,2-C2B10H11 and 7-H3N-7-CB10H12 With carboxylic acid containing substrates was investigated. The reactions studied using the coupling reagent, 1,1'-carbonyldiimidazole, resulted in the preparation of a series of amides in moderate to high yield. The relative importance of this type of research resides in the fact that it allows the introduction of amino acids in close contact with the carborane cage. These compounds can constitute a new generation of substrates useful in boron neutron capture therapy. Our emphasis lies in the development of suitable synthetic schemes allowing the preparation of this type of compound. Experimental details and analytical data supporting the formulation of the prepared compounds are reported.
