Actinaurispora siamensis gen. nov., sp. nov., a new member of the family Micromonosporaceae.
Two actinomycete strains isolated from temperate peat swamp forest soil in Chiang Mai Province, Thailand are proposed to belong to a new genus, Actinaurispora gen. nov., with strain CM2-8(T) (=JCM 15677(T)=BCC 34762(T)) as the type strain. Expand
New macrolactins from a marine Bacillus sp. Sc026.
The chemical structures of 1-3 were elucidated on the basis of spectral data analyses and literature data comparison and exhibited antibacterial activity against Bacillus subtilis and Staphylococcus aureus. Expand
Screening for phosphodiesterase inhibitory activity of Thai medicinal plants.
Thai biodiversity was the great sources of PDE inhibitors, as seven from nineteen aphrodisiac and neurotonic plants as well as three from twelve Leguminosae plants showed potent PDEs inhibitory activity. Expand
Synthesis and anti-herpes simplex viral activity of monoglycosyl diglycerides.
A study of the structure-activity relationships of the synthetic monoglycosyl diglycerides indicated that the fatty acyl moieties were critical for inhibitory action with higher activity displayed as the acyl groups became more olefinic in character. Expand
Kaempferia parviflora, a plant used in traditional medicine to enhance sexual performance contains large amounts of low affinity PDE5 inhibitors.
This finding provides an explanation for enhancing sexual performance in the traditional use of Kaempferia parviflora and 5,7-dimethoxyflavones should make a useful lead compound to further develop clinically efficacious PDE5 inhibitors. Expand
Micromonospora eburnea sp. nov., isolated from a Thai peat swamp forest.
Two actinomycete strains, which produced single, non-motile spores, were isolated from peat swamp forest soil in Yala Province, Thailand and represent a novel species, for which the name Micromonospora eburnea sp. Expand
Micromonospora siamensis sp. nov., isolated from Thai peat swamp forest.
Genotypic and phenotypic data indicated that strain TT2-4T was distinguished from the phylogenetically closest relatives and merits a new species in the genus Micromonospora and the name Micromonspora siamensis sp. Expand
Distribution Patterns of the Renieramycin-Producing Sponge, Xestospongia sp., and Its Association with Other Reef Organisms in the Gulf of Thailand
The renieramycin-producing sponge, Xestospongia sp., is a coral reef inhabitant occurring in the Gulf of Thailand. The distribution patterns of Xestospongia sp. and its association with otherExpand
Vobasinyl‐iboga bisindole alkaloids, potent acetylcholinesterase inhibitors from Tabernaemontana divaricata root
The roots of the Thai medicinal plant, Tabernaemontana divaricata, were investigated for their content of acetylcholinesterase inhibitors and the inhibitory activity of 19,20‐dihydroervahanine A was proved to be specific, reversible and competitive. Expand
Hectochlorin and morpholine derivatives from the Thai sea hare, Bursatella leachii.
Investigation of the EtOAc extract from the Thai sea hare resulted in the isolation of a potent stimulator of actin assembly, hectochlorin, and its new derivative, deacetylhectochlorIn, which exhibited more potent cytotoxicity than 1 against different human carcinoma cell lines. Expand
