Lewis-Acid-Catalyzed Decarboxylative Annulation of 2‑Aminoindole-3-Carboxylate with Ynals Involving [3 + 2] Spirocycloaddition and 2,3-Aza Migration

open access: yes, 2020
2-Aminoindole-3-carboxylates undergo a Lewis-acid-catalyzed decarboxylative annulation with ynals to afford dihydrochromeno-fused δ-carbolines through a 2,3-aza migration, via a spirocyclic intermediate generated from an initial [3 + 2 ...

Effects of ursodeoxycholic acid on synthesis of cholesterol and bile acids in healthy subjects [PDF]

open access: yes, 2004
Background/Aims: Ursodeoxycholic acid ( UDCA) decreases biliary secretion of cholesterol and is therefore used for the dissolution of cholesterol gallstones.

Brønsted-Acid-Catalyzed Synthesis of 3‑Alkoxy and 3‑Sulfamido Indanones via a Tandem Cyclization

open access: yes, 2019
Brønsted-acid-catalyzed allylic substitution reactions of the in situ generated 3-hydroxy indanones with alcohols and sulfamides were investigated, which provided a facile route for the synthesis of a large variety of 3-alkoxy and 3-sulfamido indanones ...

Cardiac actions of thyroid hormone metabolites [PDF]

open access: yes, 2017
Thyroid hormones (THs) have a major role in regulating cardiac function. Their classical mechanism of action is genomic. Recent findings have broadened our knowledge about the (patho)physiology of cardiac regulation by THs, to include non-genomic actions

Efficient and specific analysis of red blood cell glycerophospholipid fatty acid composition. [PDF]

open access: yes, 2012
Red blood cell (RBC) n-3 fatty acid status is related to various health outcomes. Accepted biological markers for the fatty acid status determination are RBC phospholipids, phosphatidylcholine, and phosphatidyletholamine.

Conformations of 2-phenyl-3-pyridylpropenoic acid (alpha-phenyl pyridylcinnamic acid) dimers – A computational study [PDF]

open access: yes, 2005
Motivation. Cinnamic acid analogs are not only important parts of the shikimic acid metabolic pathway of higher plants but it is possible to assemble, particularly from those containing oxygen or nitrogen heteroatoms, various patterned structures kept ...

Differences in fatty acid composition between cerebral brain lobes in juvenile pigs after fish oil feeding [PDF]

open access: yes, 2008
Very long-chain n-3 PUFA from fish are suggested to play a role in the development of the brain. Fish oil feeding results in higher proportions of n-3 PUFA in the brains of newborn piglets. However, the effect of fish oil on the fatty acid composition of

Metabolomics of dietary fatty acid restriction in patients with phenylketonuria [PDF]

open access: yes, 2012
Patients with phenylketonuria (PKU) have to follow a lifelong phenylalanine restricted diet. This type of diet markedly reduces the intake of saturated and unsaturated fatty acids especially long chain polyunsaturated fatty acids (LC-PUFA).

Acid-Catalyzed Formation of Hexahomooxacalix[3]arenes

open access: yes, 2016
The role of acid catalysis in oxacalix[3]arene synthesis has been investigated. A range of acids were used to optimize the yield of tert-butyloxacalix[3]arene, the most efficient being p-toluenesulfonic acid, which, with local symmetry complementary with

Omega-3 Index and Sudden Cardiac Death [PDF]

open access: yes, 2010
Sudden cardiac death (SCD) is an unresolved health issue, and responsible for 15% of all deaths in Western countries. Epidemiologic evidence, as well as evidence from clinical trials, indicates that increasing intake and high levels of eicosapentaenoic ...
