The Catalytic Enantioselective, Protecting Group-Free Total Synthesis of (+)-Dichroanone [PDF]

open access: yes, 2006
Herein we report the first enantioselective total synthesis of (+)-dichroanone, confirming the absolute configuration of the natural product. This protecting group-free route features the first application of our enantioselective Tsuji allylation in the ...

Synthesis and biological evaluation of anti-Toxoplasma gondii activity of a novel scaffold of thiazolidinone derivatives [PDF]

open access: yes, 2017
We designed and synthesised novel N-substituted 1,3-thiazolidin-4-one derivatives for the evaluation of their anti-Toxoplasma gondii efficacy. This scaffold was functionalised both at the N1-hydrazine portion with three structurally different moieties ...

Cyclization of 1,2:3,4-di-O-isopropylidene-α-D-galacto-1,6-hexodialdo-1,5-pyranose acylhydrazone and semicarbazone [PDF]

open access: yes, 2013
Cyclization of 1,2:3,4-di-O-isopropylidene-α-D-galacto-1,6-hexodialdo-1,5-pyranose benzoylhydrazone using acetylating mixtures led us to the corresponding (2R)- and (2S)-5- phenyl-1,3,4-oxadiazoline derivatives.

Sinteza N4-(2,4-dimetilfenil) semikarbazona kao inhibitori 4-aminobutirat aminotransferaze [PDF]

open access: yes, 2006
Several 2,4-dimethylphenyl substituted semicarbazones were synthesized in three steps involving aryl urea and aryl semicarbazide formations. The structures were confirmed by spectral and elemental analyses.

Food Safety At The Molecular Level: Crossing The Ecological Threshold [PDF]

open access: yes, 2011
The zero-tolerance precautionary approach to ban certain antibiotics from food has proven unworkable as a result of continuing analytical progress. New regulatory standards on chemical residues do not adequately address the situation, leaving technical ...

Association between metabolically healthy central obesity in women and levels of soluble receptor for advanced glycation end products, soluble vascular adhesion protein-1, and the activity of semicarbazide-sensitive amine oxidase. [PDF]

open access: yes, 2017
AIM: To determine the levels of circulating soluble receptor for advanced glycation end products (sRAGE), as a biomarker of risk of metabolic syndrome and cardiovascular disease development in centrally obese (CO) women considered metabolically healthy (
