Objectives: 7-prenyloxycoumarins are a group of secondary metabolites that are found mainly in plants belonging to the Rutaceae and Umbelliferae families. This study was designed to evaluate and compare the cytotoxic and apoptotic activity of 7-prenyloxycoumarin compounds and herniarin on MCF-7, a breast carcinoma cell line. Materials and Methods: Cells were cultured in RPMI medium and incubate...
Purine nucleoside phosphorylase (PNP), from calf spleen, human erythrocytes and E. coli have been examined with regard to structural requirements of substrates and inhibitors. Kinetic parameters (Km, Vmax/Km) for a variety of N(1) and/or N(7)-methylated analogues of guanosine, inosine and adenosine have been evaluated for all three enzymes. The substrate and/or inhibitor properties of purine ri...
