Benzoquinazoline derivatives as new agents affecting DNA processing
摘要:
A new series of benzo[h]quinazoline and benzo[f]quinazoline derivatives was prepared and studied for the biological activity. The compounds carrying a dimethylaminoethyl side chain (6c, 8c and 12) inhibit cell growth. The ability to form a molecular complex with DNA and to interfere with topoll and topol relaxation activity was evidenced for the most active 6c and 8c, along with the capacity to induce apoptosis on HeLa cells.

A novel synthetic pathway to benzoquinazolines from naphthylamines is reported. Benzoquinazoline nucleus was cyclized in good yield from N-protected naphthylamines using hexamethylenetetramine in TFA and potassium ferricyanide in aqueous ethanolic KOH. This method is efficient and convenient with respect to previously reported synthetic pathways.
