Chemoenzymatic Synthesis of Triazololactams Structurally Related to Pancratistatin [PDF]

, 2017
Four tricyclic lactams that structurally resemble alkaloids with the pancratistatin skeleton were synthetized from bromobenzene by a chemoenzymatic strategy.

Can phylogeny predict chemical diversity and potential medicinal activity of plants? A case study of amaryllidaceae [PDF]

, 2012
Background During evolution, plants and other organisms have developed a diversity of chemical defences, leading to the evolution of various groups of specialized metabolites selected for their endogenous biological function.

Insecticidal activity of a protein extracted from bulbs of Phycella australis Ravenna against the aphids Acyrthosiphon pisum Harris and Myzus persicae Sulzer [PDF]

, 2016
Aphids cause significant losses in many agricultural crops and in many cases cause repeated insecticide sprays, which increase the risk of resistance. Therefore, other alternatives are needed to control them.

Open data phylometabolomics reveals turnover-dominated chemical divergence and clade-specific physicochemical regimes across angiosperms. [PDF]

Plant J
Significance Statement Using an open, reproducible phylometabolomics pipeline (LOTUS + standardized taxonomy; ~77 000 occurrences), we show that angiosperm chemodiversity diverges primarily by turnover (replacement), not nested accumulation. Despite this dynamism, major clades occupy distinct physicochemical regimes, revealing conserved constraints ...

Daffodils as Potential Crops of Biologically-active Compounds: Assessment of 40 Ornamental Taxa for their Alkaloid Profile and Cholinesterases Inhibition Activity

Natural Product Communications, 2018
Many varieties of Narcissus (Amaryllidaceae) are planted on a large scale for ornamental purposes and at the same time they represent a rich reservoir of potential small chemical molecules that display several medicinal properties.
