(A) [Tris(1,10-phenanthroline)lanthanum(III)] trithiocyanate (KP772; FFC24). KP772-induced cytotoxicity against (B) KB-3-1 or (C) GLC-4 and their chemoresistant sublines KBC-1 (P-gp-overexpressing) or GLC-4/adr (MRP1-overexpressing) was measured using MTT assay after 72 h drug exposure. (D) Clonogenic survival of KB-3-1 and KBC-1 cells was determined after exposure to the indicated concentrations of KP772 for 6 days. Cell colonies were visualised by crystal violet staining.
