title: Effects of 5-campestenone (24-methylcholest-5-en-3-one) on the type 2 diabetes mellitus model animal C57BL/KsJ-db/db mice.
abstract: We examined the therapeutic effects of dietary exposure to 5-campestenone (24-methylcholest-5-en-3-one), an enone derivative of campesterol, in C57BL/KsJ-db/db mice, which are an animal model of obese type 2 diabetes. Blood glucose levels of db/db mice linearly increased from 270 to 720 mg/dl in 10 weeks, an approximately 7-fold difference from the levels of db/+m mice. The 0.3 % dietary exposure to 5-campestenone caused a marked reduction in blood glucose levels of 330 mg/dl after 10 weeks of feeding with a concomitant inhibition of glucose excretion in urine. Only slight efficacy was observed with 0.1 % dietary exposure to this chemical in db/db mice. Significant decreases of plasma triglyceride and plasma free fatty acid were also observed in db/db mice at a 0.3 % dose. However, feed efficiency and body-weight gain in db/db mice was improved by 5-campestenone. No obvious anomaly due to consumption of 5-campestenone was detected by necropsy or clinical observation.
