Can new herbicide discovery allow weed management to outpace resistance evolution?

Pest Manag Sci 2021 May 4. Epub 2021 May 4.

Bayer AG, Industriepark Höchst, 65926 Frankfurt am Main, Germany.

While herbicides are the most effective and widely adopted weed management approach, the evolution of multiple herbicide resistance in damaging weed species threatens the yield and profitability of many crops. Weeds accumulate multiple resistance mechanisms through sequential selection and/or gene flow, with long-range and international transport of herbicide resistant weeds proving to be a serious issue. Metabolic resistance mechanisms can confer resistance across multiple sites of action and even to herbicides not yet discovered. Read More

Landscape rules predict optimal superhighways for the first peopling of Sahul.

Nat Hum Behav 2021 Apr 29. Epub 2021 Apr 29.

ARC Centre of Excellence for Australian Biodiversity and Heritage, James Cook University, Cairns, Queensland, Australia.

Archaeological data and demographic modelling suggest that the peopling of Sahul required substantial populations, occurred rapidly within a few thousand years and encompassed environments ranging from hyper-arid deserts to temperate uplands and tropical rainforests. How this migration occurred and how humans responded to the physical environments they encountered have, however, remained largely speculative. By constructing a high-resolution digital elevation model for Sahul and coupling it with fine-scale viewshed analysis of landscape prominence, least-cost pedestrian travel modelling and high-performance computing, we create over 125 billion potential migratory pathways, whereby the most parsimonious routes traversed emerge.

Automated synthesis of prexasertib and derivatives enabled by continuous-flow solid-phase synthesis.

Nat Chem 2021 May 19;13(5):451-457. Epub 2021 Apr 19.

Department of Chemistry, National University of Singapore, Singapore, Republic of Singapore.

Recent advances in end-to-end continuous-flow synthesis are rapidly expanding the capabilities of automated customized syntheses of small-molecule pharmacophores, resulting in considerable industrial and societal impacts; however, many hurdles persist that limit the number of sequential steps that can be achieved in such systems, including solvent and reagent incompatibility between individual steps, cumulated by-product formation, risk of clogging and mismatch of timescales between steps in a processing chain. To address these limitations, herein we report a strategy that merges solid-phase synthesis and continuous-flow operation, enabling push-button automated multistep syntheses of active pharmaceutical ingredients. We demonstrate our platform with a six-step synthesis of prexasertib in 65% isolated yield after 32 h of continuous execution. Read More
