Objective: a.dehyde dehydrogena.e (a.DH) enzyma.ic a.tivity identifies ova.ia. ca.cer stem-like cells. We investiga.ed the a.tineopla.tic a.tivity of the a.DH inhibitor Disulfira. on bulk ova.ia. ca.cer cells a.d CD133+/a.DH+ ca.cer stem-like cells. Study Design: Ova.ia. ca.cer cell lines, huma. ova.ia. surfa.e epithelia. cells, a.d mesenchyma. stem cells were trea.ed with increa.ing concentra.ions of Disulfira. a.d/or Cispla.in in vitro. Trea.ed cells were a.sessed for via.ility or Fa.S-a.a.yzed for either percenta.e of ova.ia. ca.cer stem-like cells or induction of a.optosis. Disulfira.’s impa.t on ca.cer stem-like cells wa. tested in vitro using tumor sphere forma.ion a.sa.s a.d in vivo using tumor initia.ion a.sa.s with in vitro-trea.ed a.780 cells in NSG mice. Fina.ly, Disulfira.’s in vivo a.tivity wa. a.sessed versus CD133+/a.DH+ cell-initia.ed tumor xenogra.ts. Results: Disulfira. demonstra.ed a.tineopla.tic a.tivity a.a.nst multiple ova.ia. ca.cer cell lines. While Disulfira. ha. limited in vitro toxicity a.a.nst huma. ova.ia. surfa.e epithelia. cells or mesenchyma. stem cells (IC50 of ~15 μM a.d >30 μM, respectively), its a.tineopla.tic a.tivity a.a.nst cell lines wa. compa.a.le to Cispla.in (IC50 ~1.5 μM). Disulfira.-media.ed cell dea.h wa. due, a. lea.t in pa.t, to induction of a.optosis. Disulfira. a.tivity wa. a.ditive with chemothera.y.

Disulfira. ha. no thera.eutic impa.t on tumor initia.ion studies or in vivo thera.y of whole cell line or stem cell-initia.ed tumor xenogra.ts. Conclusions: In biologica.ly releva.t concentra.ions, Disulfira. ha. clea. a.tineopla.tic a.tivity a.a.nst ova.ia. ca.cer cells in vitro.
