Figure 5: Relative cytotoxic anti-neoplastic potency of the tubulin/ microtubule inhibitor, griseofulvin compared to methylselencysteine against chemotherapeutic-resistant mammary adenocarcinoma. Legend: (♦) griseofulvin; and (■) methyselenocysteine. Mammary adenocarcinoma (SKBr-3) monolayer populations were incubated 72-hours with griseofulvin or methylselenocysteine formulated at gradient concentrations and cytotoxic anti-neoplastic potency measured as a function of MTT cell vitality stain intensity relative to matched negative reference controls.
