One new curcuminoid, 3'-demethoxycyclocurcumin (1), was isolated from Curcuma xanthorrhiza as an antibabesial compound, together with p-hydroxybenzaldehyde (2) and cleomiscosin A (3) from Brucea javanica and (+)-epiloliolide (4) from Excoecaria cochinchinensis. The antibabesial activities were examined in vitro, and compounds 1-4, and diminazene aceturate were studied with IC(50) values of 16.6...
The catabolism of fungal 4-aminobutyrate (GABA) occurs via succinic semialdehyde (SSA). Succinic semialdehyde dehydrogenase (SSADH) from the acidogenic fungus Aspergillus niger was purified from GABA grown mycelia to the highest specific activity of 277 nmol min(-1) mg(-1), using phenyl Sepharose and DEAE Sephacel chromatography. The purified enzyme was specific for its substrates SSA and NAD+....
Five phenolic compounds, p-hydroxyacetophenone, 5,7-dihydroxychromone, naringenin, quercetin, and iso-americanol A, were found first time in the barley tea, together with the known compounds, p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, p-hydroxybenzoic acid, vanillic acid, and p-coumaric acid. The anti-oxidative properties were evaluated by measuring their peroxynitrite-scavenging activit...
