Postprandial Hyperglycemia Lowering Effect of the Isolated Compounds from Olive Mill Wastes - An Inhibitory Activity and Kinetics Studies on α-Glucosidase and α-Amylase Enzymes.
TL;DR: Seven compounds from olive mill wastes are isolated and investigated their antidiabetic potential through inhibition of α-glucosidase and α-amylase enzymes, one of them being novel, and it is shown that the esterification of C-1 of the furofuran ring is the key feature for the stronger activity of 1-acetoxypinoresinol 3 against both enzymes.

Yhiya Amen,Yhiya Amen,Qinchang Zhu,Hai Bang Tran,Mohamed S. Afifi,Ahmed F. Halim,Ahmed Ashour,Amira Mira,Kuniyoshi Shimizu +8 more
TL;DR: Among the compounds, lucidumol C showed potent selective cytotoxicity against HCT-116 cells with an IC50 value of 7.86 ± 4.56 µM and selectivity index (SI) >10 with remarkable cytotoxic activities against Caco-2, HepG2 and HeLa cell lines.
Journal ArticleDOI
Lucidumol D, a new lanostane-type triterpene from fruiting bodies of Reishi (Ganoderma lingzhi).
Dedi Satria,Yhiya Amen,Yhiya Amen,Yasuharu Niwa,Ahmed Ashour,Ahmed Ashour,Ahmed E. Allam,Ahmed E. Allam,Kuniyoshi Shimizu +8 more
TL;DR: The structure-activity relationship indicated that carbonyl function at C-11 is necessary to enhance the cytotoxicity of lucidumol D against proliferation of several cancer cells.
Journal ArticleDOI
Melanogenesis inhibitors from Coix lacryma-jobi seeds in B16-F10 melanoma cells
Yhiya Amen,Yhiya Amen,Enos Tangke Arung,Enos Tangke Arung,Mohamed S. Afifi,Ahmed F. Halim,Ahmed Ashour,Ryoji Fujimoto,Takahiro Goto,Kuniyoshi Shimizu +9 more
TL;DR: The results of this study suggested the potential use of Coix lacryma-jobi seeds as a skin whitening agent and reveal the seeds to be a rich source of important phytochemicals with melanogenesis inhibitory activity.
