Preformulation Studies of a Stable PTEN-PDZ Lipopeptide Able to Cross an In Vitro Blood-Brain-Barrier Model as a Potential Therapy for Alzheimer's Disease
(Springer, 2020-08-04)
PurposeAmyloid beta (A beta) drives the accumulation of excess Phosphatase and Tensin Homolog Deleted on Chromosome 10 (PTEN) at synapses, inducing synaptic depression and perturbing memory. This recruitment of PTEN to ...
Manipulating the fluorescence lifetime at the sub-cellular scale via photo-switchable barcoding
(Nature, 2020-05-18)
Fluorescent barcoding is a pivotal technique for the investigation of the microscale world, from information storage to the monitoring of dynamic biochemical processes. Using fluorescence lifetime as the readout modality ...
Co-Catalyzed C(sp3)−H Oxidative Coupling of Glycine and Peptide Derivatives
(American Chemical Society, 2017-09-22)
obalt-catalyzed selectiveα-alkylation andα-heteroarylation processes ofα-amino esters and peptide derivativesare described. These cross-dehydrogenative reactions occur undermild conditions and allow for the rapid assembly ...
Iron-Catalyzed Direct α-Arylation of Ethers with Azoles
(Royal Society of Chemistry, 2015-07-14)
The direct α-arylation of cyclic and acyclic ethers with azoles has been achieved, which features a novel iron-catalyzed cross-dehydrogenative coupling (CDC) process. This practical oxidative method allowed the efficient ...
Enantioselective Michael Addition of Aldehydes to Maleimides Organocatalyzed by a Chiral Primary Amine-Salicylamide
(MDPI, 2018-12-12)
A primary amine-salicylamide derived from chiral trans-cyclohexane-1,2-diamine was used as an organocatalyst for the enantioselective conjugate addition of aldehydes, mainly ,-disubstituted to N-substituted maleimides. The ...
Unprecedented Multicomponent Organocatalytic Synthesis of Propargylic Esters via CO2 Activation
(Wiley‐VCH, 2019-02-19)
An efficient and straightforward organocatalytic method for the
direct, multicomponent carboxylation of terminal alkynes with
CO2 and organochlorides, towards propargylic esters, is reported
for the first time. ...
Manganese-Catalyzed Multicomponent Synthesis of Tetrasubstituted Propargylamines: System Development and Theoretical Study
(Wiley-VCH, 2020-07-20)
The importance of multicomponent reactions as an efficient tool in organic synthesis is widely recognized, as the need for sustainable, practical, atom- and step-economic methodologies is becoming a crucial concept in ...
Reduced Graphene Oxide/Polymer Monolithic Materials for Selective CO2 Capture
(MDPI, 2020-04-17)
Polymer composite materials with hierarchical porous structure have been advancing in many different application fields due to excellent physico-chemical properties. However, their synthesis continues to be a highly ...
An umpolung strategy to react catalytic enols with nucleophiles
(Nature, 2019-11-20)
The selective synthesis of a-functionalized ketones with two similar enolizable positions can be accomplished using allylic alcohols and iridium(III) catalysts. A formal 1,3-hydrogen shift on allylic alcohols generates ...
Selective C(sp2)−H Halogenation of "click" 4-Aryl-1,2,3-triazoles
(American Chemical Society, 2017-02-09)
Selective bromination reactions of “click compounds” are described. Electron-neutral and electron-deficient arenes selectively undergo unprecedented Pd-catalyzed C–H ortho-halogenations assisted by simple triazoles as ...
