Figure 2. Optical properties of CFZ and CFZ analog 568 and quantitative analysis of skin pigmentation using various optical filters.

Figure 2

(a) Images of CFZ and analog 568 free base and HCl salt powders and the extent of their reflectance using 480nm, 535nm, and 623nm optical filters. (b) Images of mouse ears after 3-4 weeks of CFZ or analog 568 treatment and the extent of their reflectance using 480nm, 535nm, and 623nm optical filters. (c) Quantitative analysis of the drug powder images (n=7) and images of mouse ears after 3-4 weeks of CFZ or 568 treatment compared to untreated mice (n=3) (blue = 480nm filter; green = 535nm filter; red = 623nm filter; *p < 0.01, ANOVA single factor, Tukey's HSD).
