Coumarins in the Rutaceae
TL;DR: The biogenesis, structural diversity and distribution of simple, furano- and pyranocoumarins in the Rutaceae is reviewed and the potential value of these compounds as taxonomic markers and their possible functions are discussed.

Naturally Occurring Plant Coumarins
TL;DR: 7-hydroxycoumarin [umbelliferone, (2)], one of the most widely distributed coumarins, is often regarded as the parent, in a structural sense and also biogenetically, of a large number of the structurally more complex coumarin.

TL;DR: These compounds showed significant efficacy in L. amazonensis infected mice, providing important knowledge to improve its potential role for a future use in the treatment of cutaneous leishmaniasis.

Tasty on the outside, but toxic in the middle: grasshopper regurgitation and host plant-mediated toxicity to a vertebrate predator.
TL;DR: This study investigated the relationship between diet and predator defense in the grasshopper, Schistocerca emarginata (=lineata) and demonstrated that consumption of Ptelea trifoliata by S. emargInata can confer distastefulness as well as toxicity and enable grasshoppers to survive predator attacks.

The Proton Magnetic Resonance of Furoquinoline Alkaloids and Related Compounds
TL;DR: A survey of the proton magnetic resonance of 20 compounds of the furoquinoline and related classes discloses correlations which will be useful for future structural work in this alkaloid field as mentioned in this paper.

Solvent effects in NMR Spectroscopy : Solvent shifts of methoxyl resonances in flavones induced by benzene; an aid to structure elucidation
TL;DR: In this paper, the position and relative orientation of OMe groups in methoxyflavones can be inferred from benzene-induced solvent shifts of the OMe resonances, and the authors show that an OMe at C-5 suffers a drastic algebraic decrease in solvent shift upon the introduction of an ortho-OMe group at c-6.
