Synthesis of Triethylammonium Salts of Amidine Derivatives of closo-Borate Anions [B10H10]2– and [B12H12]2– and Study of Their Cytotoxic Properties
摘要
Abstract
A series of amidine derivatives of the closo-decaborate and closo-dodecaborate anions with triethylammonium cations were obtained. The structures of the compounds was determined by multinuclear NMR spectroscopy and ESI-mass spectrometry. Cytotoxicity of all compounds obtained was investigated by MTT method on four cell lines. It was shown that the nature of the cation does not affect the cytotoxicity of the substituted closo-borates discussed.
