2 benzoxazolinone/悪性腫瘍

Four new 2-benzoxazolinone-type alkaloids (acanthosides A-D) along with three known ones were isolated from the roots of Acanthus ilicifolius. Their structures were established by detailed interpretation of one dimensional (1D)- and two dimensional (2D)-NMR as well as high-resolution electrospray

Sweet broomweed (Scoparia dulcis) is an edible perennial medicinal herb widely distributed in tropical and subtropical regions of Asia, Africa, and the Americas. Four compounds, (2R)-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-O-β-galactopyranoside [(2R)-HMBOA-2-O-Gal],

Infection of maize (Zea mays) plants with the smut fungus Ustilago maydis triggers the formation of tumors on aerial parts in which the fungal life cycle is completed. A differential display screen was performed to gain insight into transcriptional changes of the host response. Some of the genes

Some antitumor agents known to specifically inhibit certain tumor cell enzymes were examined for activity against glycolytic enzymes and growth of the insect trypanosomatid, Crithidia fasciculata. The cytoplasmic enzymes hexokinase, alpha-glycerophosphate dehydrogenase, malic dehydrogenase, and
