Articles / Literature in focus
Articles examine noteworthy research papers: what they report, why the work matters, how the evidence supports the claims, and which questions remain open. Each entry is labeled by the contribution the paper makes — chemical diversity, biosynthesis, research methodology, or review.
review
A close reading of Newman and Cragg's 2020 J. Nat. Prod. review, the sixth census in their series, which codes all 1881 therapeutic agents approved worldwide between 01/1981 and 09/2019 by structural source and finds that only 15.7% of anticancer small molecules are wholly synthetic while 64.9% trace their structure or pharmacophore to a natural product.
research methodology
A close reading of Shin and co-workers' 2023 JACS paper, where PCR amplicons of the N–N bond-forming gene ktzT prioritize producing strains and ¹H–¹⁵N NMR signatures of ¹⁵N-labeled cultures confirm piperazic acid incorporation before any purification begins.
