d-Fructose-l-histidine (FruHis) is a ketosamine combining the d-isomer of fructose and the l-isomer of histidine into a functional group. FruHis is present in dried fruits. In interaction with lycopene, FruHis is a potential food related antioxidant and chemopreventive agent, found abundantly in dried tomatoes.[1]

Research

A group of carbohydrate derivatives present in dehydrated tomato products interact with lycopene against prostate cancer.[2][3] FruHis strongly synergizes with lycopene against the proliferation of highly metastatic rat prostate cancer cell lines in vitro. The FruHis/lycopene combination significantly inhibits in vivo tumorigenesis in syngeneic rats. The ketosamine completely blocks DNA oxidative degradation at >250 μmol/L in vitro, whereas neither ascorbate nor phenolic antioxidants from tomato are effective protectors.

Based on these studies, the American Association for Cancer Research has concluded that FruHis may exert tumor-preventive effect through its antioxidant activity and interaction with lycopene.[4]
