Toxicity profiles of gossypol versus apogossypol in normal mice. Female Balb/c mice (7 weeks old) (n = 6 per group) were orally administered vehicle control (■), 120 μmol/kg gossypol (•), or 120 μmol/kg apogossypol (♦) 5 times weekly for 3 weeks. (A) Percentage survival of mice is shown over time. (B) Body weight is shown over time, in grams (mean ± standard deviation [SD]). Data are representative of several experiments involving a total of 20 gossypol-treated, 40 apogossypol-treated, and 20 vehicle control–treated mice.
