Anti-plasmin inhibitor. VI. Structure of phlorofucofuroeckol A, a novel phlorotannin with both dibenzo-1,4-dioxin and dibenzofuran elements, from Ecklonia kurome Okamura.
TLDR
The structure has been elucidated to be 1,11-di(3,5-dihydroxyphenoxy)- benzofuro[3,2-a]dibenzo[b,e][1,4]dioxin-2,4,8,10,14-pentaol on the basis of the spectral data.
Structures of americanol A and isoamericanol A having a neurotrophic property from the seeds of Phytolacca americana.
TLDR
Isoamericanol A, americanol A, and americanin A have been found to enhance choline acetyltransferase activity at 10(-5) M in a cultured neuronal cell system derived from fetal rat hemisphere.
Antibacterial Activity of Pisiferic Acid and Its Derivatives against Gram-negative and-positive Bacteria
TLDR
In the mode of action of the pisiferic acid species on the bacterial macromolecule, peptidoglycan synthesis was predominantly inhibited in B. subtilis, while nonspecific inhibition was observed in P. vulgaris.
Structure and synthesis of 11,12,13-trihydroxy-9Z,15Z-octadecadienoic acids from rice plant suffering from rice blast disease.
Structural elucidation including the absolute configuration was carried out on the trihydroxyoctadecadienoic acids isolated from rice plant suffering from rice blast disease.
Structure of an anti-plasmin inhibitor, eckol, isolated from the brown alga Ecklonia kurome Okamura and inhibitory activities of its derivatives on plasma plasmin inhibitors.
TLDR
The structure of eckol has been elucidated based on the spectral data, in particular, by means of negative nuclear Overhauser effect (NOE), and finally established as 1-(3,5-dihydroxyphenoxy)-2,4,7,9-tetrahydroxydibenzo-1,4-dio xin by X-ray analysis.
