Peroxisome proliferator-activated receptor .gamma. -PPAR.gamma.) is a central regulator of adipocyte differentiation and is the principle target of the thiazolidinedione -TZD) class of antidiabetic drugs. Harmine is a .beta.-carboline alkaloid that was first isolated from seeds of Peganum harmala -Syrian rue) and Banisteriopsis caapi. Recent work indicates that harmine is a unique regulator of PPAR.gamma. expression that acts by inhibiting the Wnt signalling pathway in a cell-specific manner. Administration of harmine -30 mg/kg) to obese db/db mice resulted in reduced blood glucose, free fatty acids, and triglyceride levels, delayed hyperglycemia, and improved insulin sensitivity. Harmine also attenuates inflammatory gene expression -TNF.alpha., IL-1.beta., iNOS) and macrophage accumulation in adipose tissue.
