CDN1163 improves glucose homeostasis and metabolic parameters in ob/ob mice. CDN1163 was administrated for 5 consecutive days (D0 to D4). A, fasting blood glucose levels after first injection of CDN1163 at day 1 (D1). Fasting blood glucose levels (B) and body weight (C) were determined weekly until day 50. D, average food intake in lean, vehicle-treated obese (Ob) and CDN1163-treated obese (Ob+CDN) mice (n = 10/group). E, body composition analyzed for 7 days in a separate cohort (n = 8) before and after 5 days of CDN1163 treatment in vehicle-treated obese (Ob) and CDN1163-treated obese (Ob+CDN) mice. Indirect calorimetry conducted for the last 4 days was assessed oxygen consumption (F), respiratory exchange ratio (RER) (G), and physical activity and caloric intake (H). J, mRNA expression of UCP1, UCP2, and UCP3 in brown tissue in lean, vehicle-treated obese (Ob) and CDN1163-treated obese (Ob+CDN) mice (n = 5). I, glucose levels and body weight after CDN1163 treatment of lean mice. CDN1163 was administrated for 5 consecutive days (D0 to D4). Fasting blood glucose levels and body weight were determined weekly until day 30 in lean plus vehicle (LN+Veh) and lean plus treatment (LN+CDN) mice (n = 6/group). Body weight values for day 1 (D1) and day 31 (D31) are shown. *, p < 0.05; **, p < 0.01; ***, p < 0.001, lean versus obese; #, p < 0.05; ##, p < 0.01; ###, p < 0.001, obese versus CDN1163-treated obese mice.
