Oxidative stress, inflammation, and hyperlipidemia are common factors involved in the pathophysiology of atherosclerosis and type 2 diabetes. We have previously developed multifunctional antidyslipidemic derivatives with antioxidant and antiatherogenic properties. We now report the design, synthesis, and evaluation of two such novel derivatives that incorporate a structural moiety of the antidiabetic agent succinobucol. The new compounds exhibited a much improved in vitro antioxidant and squalene synthase inhibitory activity (at lower micromolar concentrations) as well as a significant antihyperlipidemic effect, reducing plasma total cholesterol, triglycerides, and MDA by 65-90%. Compound 2 also indicated a good anti-inflammatory activity, decreasing edema by 44%, while it was further evaluated for its antidiabetic activity using a type 2 diabetes experimental mouse model. After 7 weeks of administration, it produced a significant antihyperglycemic and antihyperlipidemic activity. In conclusion, rational drug design led to a compound combining improved antioxidant, antidyslipidemic, and antidiabetic action that may serve as a potential therapeutic strategy in metabolic syndrome disorders.
