Snol-A, but not Snin-I, caused potent cytotoxicity to cancer cells. (A,B) Viability of control, Snol-A (A) and Snin-I (B) treated (48 h) cancer cells (SKOV-3, U2OS, Saos-2 and MDA-MB-231). Snol-A, but not Snin-I, showed dose-dependent toxicity. (C) Phase contrast images of control and treated SKOV-3 and U2OS cells; Snol-A, not Snin-I, treated cells showed stressed morphology marked by flat, irregular and branched phenotypes. (D) Colony-forming assay showing crystal violet stained colonies in control and Snol-A treated U2OS, SKOV-3, Saos-2 and MDA-MB-231 cancer cells. Quantitation of colony forming assay is shown on the right.
