Ecological leads for natural product discovery: novel sesquiterpene hydroquinones from the red macroalga Peyssonnelia sp.

New sesquiterpene hydroquinones from the Caribbean sponge Aka coralliphagum

Four new sulfated sesquiterpene hydroquinones siphonodictyals E1-E4 (1-4) and cyclosiphonodictyol A (5) were isolated from a sample of the Caribbean sponge Aka coralliphagum collected off the coast of San Salvador in the Bahamas. The structures of the new compounds were elucidated on the basis of mass spectrometric and NMR spectroscopic analysis. Compounds 1-4 are derivatives of siphonodictyal ...

Genomics for natural product discovery

The Natural Product Discovery Institute contains a set of more than 30 000 fungal and actinomycete organisms that can be used for natural product discovery. The natural product library contains purified compounds, partially purified column fractions, and crude extracts from natural product-producing organisms. The collection is available for screening. This site describes a roadmap for analysin...

Discovery of Novel Antiangiogenic Marine Natural Product Scaffolds.

Marine natural products (MNPs) are recognized for their structural complexity, diversity, and novelty. The vast majority of MNPs are pharmacologically relevant through their ability to modulate macromolecular targets underlying human diseases. Angiogenesis is a fundamental process in cancer progression and metastasis. Targeting angiogenesis through selective modulation of linked protein kinases...

Guiding principles for natural product drug discovery.

Natural products (NPs) have historically been a fertile source of new drugs for the pharmaceutical industry. However, this once-popular approach has waned considerably over the past two decades as the high-throughput screening of megalibraries comprised mainly of molecules with non-natural (synthetic) motifs has unfolded. Contemporary high-throughput screening libraries contain molecules compli...
