Abstract
Novel quinazolines 4–11, 15 and triazoloquinazolines 12–14 bearing biologically active
sulfonamide moieties were synthesized. All the newly synthesized compounds were evaluated
for their in vitro anticancer activity against liver cancer cell line (HEPG2). Some of the screened
compounds exhibited interesting cytotoxic activity compared to doxorubicin as a reference
drug. The most active compounds 13 and 15 were selected and evaluated for their ability
to enhance the cell killing effect of γ-radiation, compound 15 was superior to doxorubicin
in radiation combination therapy.
