From sequence-defined macromolecules to macromolecular pin codes [PDF]

open access: yes, 2020
Dynamic sequence-defined oligomers carrying a chemically written pin code are obtained through a strategy combining multicomponent reactions with the thermoreversible addition of 1,2,4-triazoline-3,5-diones (TADs) to indole substrates.

Influence of blood meal on the responsiveness of olfactory receptor neurons in antennal sensilla trichodea of the yellow fever mosquito, Aedes aegypti [PDF]

open access: yes, 2010
In female Aedes aegypti L. mosquitoes, a blood meal induces physiological and behavioral changes. Previous studies have shown that olfactory receptor neurons (ORNs) housed in grooved peg sensilla on the antennae of Ae.

Relationship between Aldose reductase and superoxide dismutase inhibition capacities of indole-based analogs of melatonin derivatives [PDF]

open access: yesArchives of Biological Sciences, 2009
Aldose reductase (AR) has been implicated in the etiology of diabetic complications. Under diabetic conditions, the elevated vascular glucose level causes an increased flux through the polyol pathway, which induces functional and morphological changes ...

Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets

open access: yes, 2015
We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan, methyl-tryptophan, and indole. The molecular interaction occurring through
