We examined the effects of halogens on the production of salinosporamide A (NPI-0052) by the obligate marine actinomycete Salinispora tropica NPS465, specifically the production of analogs containing halogens other than chlorine. Adding NaF, NaBr and

Four novel diterpenoids, spongiabutenolides A – D (2–5), all of which contain a γ-hydroxybutenolide moiety, have been isolated from a Philippines marine sponge of the genus Spongia. The structures of spongiabutenolides A – D (2–5) and the me

Polyalkyl pyran-4-ones 1a-c were irradiated in methanol or ethanol. Although the expected solvent trapping products 3 could be observed, extended irradiation times allowed exclusive formation of secondary photoproducts 4 and 5 in combined yields of 3

During the course of our screening program designed to discover novel anticancer and anti-infective agents from marine microorganisms, a strain of Streptomyces aureoverticillatus (NPS001583) isolated from a marine sediment was found to produce a nove

Fused bicyclic 4-pyrones were prepared by condensation of enamines derived from cyclic ketones with diketene or substituted 1,3-dioxin-4-ones. Photolysis in a hydroxylic medium led to bicyclo[n3.0]alkenones bearing oxygenation at both angular positio
