New butenolides from two marine streptomycetes.
Chemical examination of two marine Streptomycetes has resulted in the isolation of four new butenolides, identified by interpretation of the 2D NMR and mass spectral data. Expand
Antineoplastic agents. 558. Ampelocissus sp. cancer cell growth inhibitory constituents.
An investigation of the Phillippine Ampelocissus sp. roots for cancer cell growth inhibitory components led to the isolation of a new acetogenin characterized as 22-epicalamistrin (1) employingExpand
Antineoplastic agents. 570. Isolation and structure elucidation of bacillistatins 1 and 2 from a marine Bacillus silvestris.
Two new cyclodepsipeptides designated bacillistatins 1 (1) and 2 (2) have been isolated from cultures of a sample of Bacillus silvestris that was obtained from a Pacific Ocean (southern Chile) crab.Expand
New sesquiterpene quinols from a Micronesian sponge, Aka sp.
Three new sesquiterpene quinols were isolated along with halistanol sulfate from a marine sponge of the genus Aka collected from Yap Island, Federated States of Micronesia and their structures were determined from spectral data. Expand
Antineoplastic Agents. 554. The manitoba bacterium Streptomyces sp.
A Streptomyces sp. isolated from riverbank soil in Manitoba, Canada, was found to contain two cancer cell growth inhibitories: diazaanthraquinone 1 and 3-(hydroxyacetyl)indole (8). The structuresExpand
Isolation and Structure of Cancer Cell Growth Inhibitory Tetracyclic Triterpenoids from the Zimbabwean Monadenium lugardae.
The Zimbabwean medicinal plant Monadenium lugardae was evaluated as a potential source of new anticancer constituents and lugardstatins 1 (1) and 2 (2) had good cancer cell growth inhibitory activity. Expand
5-(2-Methylphenyl)-4-pentenoic Acid from a Terrestrial Streptomycete
Abstract From a terrestrial Streptomycete, GW 10/2517, the new 5-(2-methylphenyl)-4-pentenoic acid (1a) was isolated. The structure of 1a was proven by a detailed spectroscopic analysis and byExpand
Antimicrobial activity of selected Native American seeds
Antibacterial activity profiles of 22 seed extracts against five pathogens were evaluated using disc diffusion assay and Helenium flexuosum and Epilobium glandulosum exhibited moderate activity. Expand
Using alamarBlue ® Cell Viability Assay to Screen for Putative Antimicrobial Products
The number of pathogens resistant to antibiotics in hospitals and communities is on the rise. The costs associated with the treatment and work loss run into billions of dollars annually. Our researchExpand
