Novel N-(bicyclic heterocyclyl)-4-piperidinamines of the formula
the pharmaceutically acceptable acid addition salts and the stereochemically isomeric forms thereof, which compounds are useful as anti-allergic agents; pharmaceutical compositions containing such compounds as an active ingredient; methods of preparing said compounds and pharmaceutical compositions; new intermediates, used in the preparation of said compounds, which are themselves useful as anti-allergic agents and pharmaceutical compositions containing the latter as active ingredients.
Imidazole-containing heterocycles: Imidazopyridines, imidazopyrimidines and imidazopyra-zines can exist more tautomeric forms than benzimidazoles. Their regioselectivities were determined for N-alkylations with 4-fluorobenzyl bromide under basic conditions (K2CO3) in DMF. We observed that, regioisomers were mainly formed as a mixture in this reaction and N-benzylation occurs at a higher ratio on six membered heterocycles. Their structural assignments were made with the use of two-dimensional H-1-H-1 NOE (nuclear overhauser effect spectroscopy, NOESY). Complementary structural informationwas provided by 2D-HMBC spectra of the compounds. Synthesized compounds were tested for in vitro cytotoxic activities against Human colon cancer cell line (HCT-116) and leukemia cell lines (K562 and HL-60) by MTT test. Among them, imidazopyridine analogue 10, bearing bromine atom at the C-6 position of the pyridine moiety, gave the lowest IC50 value with 6-7 mu g/mL against all three cancer cell lines.
