Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

The Synthesis of homochiral ligandsand their application to asymmetric fluorinating reagents [PDF]

open access: yes, 1994
This thesis is concerned with the synthesis of homochiral ligands and their application to asymmetric fluorinations. Initial work focused on the synthesis of homochiral pyridine based ligands and the determination of their optical purity.

Asymmetric methodologies for the construction of 5,7,5- and 6,6,6-tricyclic sesquiterpene lactones towards the synthesis of Arglabin

open access: yes, 2007
Many naturally extracted guaianolides (i.e. GLs) and pseudoguaianolides are based on the 5,7,5-fused ring skeleton and they show a broad biological profile. Among them, Arglabin has attracted special attention due to its promising antitumor and cytotoxic

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Adventure in Asymmetric Hydrogenation: Synthesis of Chiral Phosphorus Ligands and Asymmetric Hydrogenation of Heteroaromatics

open access: yes, 2011
Catalytic asymmetric hydrogenations of prochiral unsaturated compounds, such as olefins, ketones, and imines, have been intensively studied and are considered as a versatile method of the synthesis of chiral compounds due to atom economy and operational ...

Development of non-nucleoside reverse transcriptase inhibitors (NNRTIs): our past twenty years

open access: yesActa Pharmaceutica Sinica B, 2020
Human immunodeficiency virus (HIV) is the primary infectious agent of acquired immunodeficiency syndrome (AIDS), and non-nucleoside reverse transcriptase inhibitors (NNRTIs) are the cornerstone of HIV treatment.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Molecular docking investigation of cytotoxic phenanthrene derivatives

open access: yesComptes Rendus. Chimie, 2020
Our previous experimental work indicated that the presence of ester functionality in phenanthrene derivatives D-1 and D-2 leads to potent cytotoxicity against the Caco-2 cell line. The present work is based on th-is experimental result.
