Diversity and carbon storage across the tropical forest biome
Tropical forests are global centres of biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but theExpand
Asynchronous carbon sink saturation in African and Amazonian tropical forests
Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 per cent of anthropogenic carbon dioxideExpand
SB-202742, a novel beta-lactamase inhibitor isolated from Spondias mombin.
SB-202742 [1], an anacardic acid derivative possessing beta-lactamase inhibitory activity, has been isolated from a hexane extract of the plant, Spondias mombin. Its isolation, structureExpand
Identification of a Series of Tricyclic Natural Products as Potent Broad-Spectrum Inhibitors of Metallo-β-Lactamases
ABSTRACT This work describes the discovery and characterization of a novel series of tricyclic natural product-derived metallo-β-lactamase inhibitors. Natural product screening of the Bacillus cereusExpand
Identification of 7α-hydroxycephalosporin C as an intermediate in the methoxylation of cephalosporin C by a cell free extract of Streptomyces clavuligerus
Incubation of cephalosporin C with a cell free extract of Streptomyces clavuligerus resulted in the formation of 7α-hydroxycephalosporin C; the same crude enzyme preparation was shown to methylateExpand
On the delineation of tropical vegetation types with an emphasis on forest/savanna transitions
Background: There is no generally agreed classification scheme for the many different vegetation formation types occurring in the tropics. This hinders cross-continental comparisons and causesExpand
SB-204900, a novel oxirane carboxamide from Clausena lansium
SB-204900 (1), a novel oxirane carboxamide, has been isolated from a hexane extract of the fruit tree Clausena lansium (Rutaceae). The structure of 1 was determined by detailed spectroscopic methodsExpand
New quinone antibiotics of the granaticin type, isolated from Streptomyces lateritius. II. Structure determination.
A number of new granaticin type quinone antibiotics have been isolated from Streptomyces lateritus ATCC 19913. Spectroscopic evidence is presented which has led to the structure elucidation of threeExpand
Non-structural carbohydrates mediate seasonal water stress across Amazon forests
Non-structural carbohydrates (NSC) are major substrates for plant metabolism and have been implicated in mediating drought-induced tree mortality. Despite their significance, NSC dynamics in tropicalExpand
