Marine Natural Products. XXVII. Distribution of Lanostane-Type Triterpene Oligoglycosides in Ten Kinds of Okinawan Sea Cucumbers
Triterpene-oligoglycoside constituents in ten sea cucumber species inhabiting Okinawan coral reefs were investigated. Several antifungal oligoglycosides were isolated from six species [stichlorosidesExpand
Marine natural products. XXXIV. Trisindoline, a new antibiotic indole trimer, produced by a bacterium of Vibrio sp. separated from the marine sponge Hyrtios altum.
A new antibiotic indole trimer was isolated, together with a known dioxopiperazine brevianamide F, from the culture of a bacterium of Vibrio sp. Expand

In this age of modern era, the use of internet must be maximized, as one of the benefits is to get the on-line bioactive marine natural products book, as the world window, as many people suggest. Expand
Dehatrine, an antimalarial bisbenzylisoquinoline alkaloid from the Indonesian medicinal plant Beilschmiedia madang, isolated as a mixture of two rotational isomers.
Through bioassay-guided separations of the chemical constituents of the Indonesian medicinal plant Beilschmiedia madang BL. a bisbenzylisoquinoline alkaloid was obtained as the major antimalarialExpand
Control of phenotypic expression of cultured B16 melanoma cells by plant glycosides.
The present observations suggest that the differentiation and growth capacity of this B16 melanoma subline are independent phenotypic expressions. Expand
Sphingolipids and glycerolipids. I. Chemical structures and ionophoretic activities of soya-cerebrosides I and II from soybean.
Two glycosphingolipids named soya-cerebrosides I and II were isolated from soybean, the seeds of Glycine max Merrill (Leguminosae), and their chemical structures have been elucidated on the basis ofExpand
Indonesian medicinal plants. VIII. Chemical structures of three new triterpenoids, bruceajavanin A, dihydrobruceajavanin A, and bruceajavanin B, and a new alkaloidal glycoside, bruceacanthinoside,
Three new apotirucallane-type triterpenoids isolated from the stems of Brucea javanica, a traditional medicine used to treat malaria in the Bengkulu area, Sumatra, Indonesia, were shown to inhibit growth of the cultured malarial parasite Plasmodium falciparum K1 of a chloroquine-resistant strain.
