Constituents of Caesalpinia crista from Indonesia.
Among the isolated compounds, caesalpinin N (7) represents the first example of furanocassane-type diterpene possessing an aldehyde group at C-14, and is determined based on the spectroscopic analysis.
Cassane- and norcassane-type diterpenes from Caesalpinia crista of Indonesia and their antimalarial activity against the growth of Plasmodium falciparum.
The isolated diterpenes showed significant dose-dependent inhibitory effects on Plasmodium falciparum FCR-3/A2 growth in vitro and norcaesalpinin E (7) showed the most potent inhibitory activity.
Antiproliferative activity of Vietnamese medicinal plants.
Characteristic morphological change and DNA fragmentation indicated the antiproliferative activity to be due to the induction of apoptosis.
Xanthine oxidase inhibitors from the flowers of Chrysanthemum sinense.
The kinetic study indicated that acacetin 7- O-(3- O-acetyl- beta- D-glucopyranoside) displayed competitive- type inhibition like that of allopurinol, while displayed a mixed-type inhibition.
Hypouricemic effects of acacetin and 4,5-o-dicaffeoylquinic acid methyl ester on serum uric acid levels in potassium oxonate-pretreated rats.
The results demonstrated the hypouricemic action of acacetin and 4,5-O-dicaffeoylquinic acid methyl ester, which may be attributable to their xanthine oxidase inhibitory activity.
Constituents of the Vietnamese medicinal plant Streptocaulon juventas and their antiproliferative activity against the human HT-1080 fibrosarcoma cell line.
The methanolic extract of roots of Streptocaulon juventas, having shown strong antiproliferative activity against the highly metastatic human HT-1080 fibrosarcoma cell line, was subjected to
