Sinensetin is a methylated flavone found in certain citrus fruits. pocess potent antiangiogenesis and anti-inflammatory, sinensetin enhances adipogenesis and lipolysis. Sinensetin is a selective inhibitor of α-glucosidase with IC50 value of 0.66 mg/ml. Alpha-glucosidase and α-amylase inhibition could the mechanisms through which sinensetin exert its antidiabetic activity, indicating that it could have potential use in the management of non-insulin-dependent diabetes. Sinensetin inhibits inflammatory gene expression and STAT1 activation. It has meaningful anti-inflammatory properties which may be utilized in the development of novel anti-inflammatory treatments.

Norharman or beta-carboline (9H-pyrido[3,4-b]indole) is a neuroactive alkaloid first isolated from Peganum harmala L. It is implicated in a number of human diseases including Parkinson's disease, tremor, addiction and cancer. Norharman formed endogenously but external sources have been identified (among others fried meat and fish, meat extracts, alcoholic drinks, coffee brews, tobacco smoke). It inhibits monoamine oxidase and indoleamine 2,3-dioxygenase. In addition norharman binds with high affinity to imidazoline I2B receptors. Plasma norharman levels are elevated in chronic alcoholics and Parkinson's disease patients.
