Five series of chromans with urea and thiourea linkers connecting a chroman unit (ring A) and a 4-substituted benzene unit (ring B) have been prepared and evaluated relative to SHetA2 (NSC 721689) for activity against the human A2780 ovarian cancer cell line. The lead compound SHetA2 had a sulfur in place of the oxygen in ring A and a thiourea linker to ring B. The 2-Me-4-Me series (two sets of geminal
