  Bis-pyrrolyl-tetrazolyl derivatives as hybrid polar compounds: A case of lipophilic functional bioisosterism with bis-acetamides

  摘要：

  Based on previous studies on bis-acetamides that act as hybrid polar compounds to induce leukemia cell differentiation, an attempt was made to bioisosterically replace the amide moiety with the lipophilic non-classical bioisostere tetrazole. A pyrrole group was also included in the molecule in order to retain the hydrogen bond donor capability. Thus, by linking the two polar ring systems with a highly lipophilic methylene chain compounds 2-4 were synthesized and assessed for their anti-proliferative activity in combination with their ability to induce murine erythroleukemia (MEL) cell differentiation. Furthermore, an initial investigation of the structure activity relation points for the active compound 3 was undertaken by synthesizing compound 5 (a p-xylene analog) and compound 8 (a methylamidopyrrolyl analog). All compounds caused a dose-dependent inhibition of MEL cell growth but to a different extent. Compound 3 (1,6-bis[5-(1H-pyrrol-1-yl)-2H-tetrazol-2-yl]hexane) promoted erythroid differentiation in a fifty-fold lower concentration than hexamethylenebisacetamide (HMBA). Though induction of differentiation was to a lesser extent than HMBA, it caused accumulation of 80% Hb-producing cells as compared to that produced by HMBA, leading to differentiation-depended cell growth inhibition equal to that of HMBA after 96 h in culture. Compound 3 represents a potent inducer of hemoglobin gene activation in leukemic cells. (C) 2012 Elsevier Masson SAS. All rights reserved.
