A) Representative images show fixed intrathoracic organs including lung lobules with visiblenodules on the surfaces in black. Total numbers of nodules werereduced insamples treated with 7R, 7S or racemate compared to vehicle. Scale bar is 0.5 cm.
B) Lung nodules of B16-F10 melanoma cells were quantified. The number of lung nodules was significantly decreased in groups treated with R-3-CCPA, S-3-CCPA, and the Racemic-3-CCPA compared to vehicle. However, no statistically significant differences were found either between the stereoisomers or the racemate. Data represent the mean ± SEM, n = 6-8 mice. *p< 0.05 compared to vehicle analyzed by one-way ANOVA followed by Newman-Keuls multiple comparison test.
