From the deep: The title actinomycete yielded three new abyssomicins J–L. The dimeric thioether J (see scheme) represents a unique example of a masked Michael acceptor with anti‐TB properties. Mechanistic insights into the biosynthesis, biomimetic synthesis, stability, and biological mechanism of action of abyssomicins aid our understanding of, and prospects for the development of Michael‐acceptor‐based drugs.

With contributions from the global natural product (NP) research community, and continuing the Raw Data Initiative, this review collects a comprehensive demonstration of the immense scientific value of disseminating raw nuclear magnetic resonance (NMR) data, independently of, and in parallel with, classical publishing outlets.

Natural products are well known for their biological relevance, high degree of three-dimensionality, and access to areas of largely unexplored chemical space. To shape our understanding of the interaction between natural products and protein targets in the postgenomic era, we have used native mass spectrometry to investigate 62 potential protein targets for malaria using a natural-product-based fragment library. We reveal here 96 low-molecular-weight natural products identified as binding partners of 32 of the putative malarial targets. Seventy-nine (79) fragments have direct growth inhibition on Plasmodium falciparum at concentrations that are promising for the development of fragment hits against these protein targets. This adds a fragment library to the published HTS active libraries in the public domain.
