In a search for potential inhibitors of solid-tumor growth. certain alkanediylbis(oxy)-linked assemblies were synthesized kind evaluated for their cytotoxicity as bis-intercalators. Symmetrical assemblies 1b-12b were synthesized front their respective Aryl-OH and either dibromobutane or dibromohexane, while unsymmetrical ones 13-15 were prepared front Aryl(1)-OH and either Aryl(2)-O-(CH2)(4)Br or Aryl(2)-O-(CH2)(6)Br. These bis-intercalators were inactive against the growth of leukemia cells. However, some of them were active against the growth of certain solid tumors such as HOP-62, HOP-92 (non-small-cell lung cancer), SF-265, SNB-75, U251 (CNS cancer), A498 (renal cancer), and HS578T (breast cancer). Among them, [hexane-1,6-diylbis(oxy)bis(4,1-phenylene)]bis[4H-1-benzopyran] (6b) was especially active against the growth of all CNS cancer cell lines and also the growth of A498, HOP-62, and HOP-92 with GI(50) values of 17.0. 20.0, and 21.8 mum, respectively.
