Synthesis of Diosgenin-Ibuprofen Derivatives and Their Activities against Insulin-Dependent Diabetes Mellitus

抄録

The synthesis and anti-diabetes activities of diosgenin-ibuprofen derivatives were investigated. Ibuprofen (IBU) was chemically coupled with diosgenin either directly or through amino acid esters linkers. The effects of these compounds on lipopolysaccharide (LPS)-induced nitric oxide (NO) generation were assessed. The results showed spirost-5-en-3β-yl (2-(4-isobutyl-phenyl)-propionate) (4) was of better activity to suppress the production of NO in the supernatant of LPS-stimulated RAW264.7 cells. In vivo investigation on nonobese diabetic (NOD) mice indicated that compound 4 decreased the incidence of insulin-dependent diabetes mellitus (IDDM; type 1 diabetes) of NOD mice which suggested a potential activity of compound 4 against type 1 diabetes.
