A series of 1,3-bis-(heteroaryl substituted)benzene derivatives was designed as promising molecules which might increase intracellular Ca2+ level in F2408 fibroblast-like cells by affecting the Ca2+ channels on plasma membrane. Mentioned compounds were obtained by the treatment of isophtalaldehyde with benzil or 1,2-phenylenediamine derivatives. In this way, 13 compounds were synthesised and their structure elucidations were performed by IR, H-1 NMR and mass spectroscopic data and elemental analysis results. Some of the compounds showed Ca2+ being released from the intact cells. (C) 2002 editions scientifiques et medicales Elsevier SAS. All rights reserved.
