FEBS 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 ...

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

Asymmetric Synthesis of the Tetraponerine Alkaloids [PDF]
The Journal of Organic Chemistry, 2017 The asymmetric syntheses of all eight tetraponerine alkaloids (T1-T8) were achieved using the diastereoselective conjugate additions of lithium amide reagents in the key stereodefining steps. Conjugate addition of either lithium (R)-N-allyl-N-(α-methylbenzyl)amide or lithium (R)-N-(but-3-en-1-yl)-N-(α-methylbenzyl)amide to tert-butyl sorbate was ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Molecular docking investigation of cytotoxic phenanthrene derivatives
Comptes 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.

Asymmetric synthesis of (−)-codonopsinine
Tetrahedron Letters, 2011 Abstract The asymmetric synthesis of (−)-codonopsinine was achieved in 7 steps (from commercially available tert-butyl crotonate) in 5% overall yield and >99:1 dr. The key step in this synthesis involved ring-closing iodoamination of a functionalised homoallylic amine, which occurred with concomitant N-debenzylation, to give a 3-iodopyrrolidine that ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Aggregation-Induced Synthesis (AIS): Asymmetric Synthesis via Chiral Aggregates
Research, 2022 A new chiral aggregate-based tool for asymmetric synthesis has been developed by taking advantage of chiral aggregates of GAP (Group-Assisted Purification) reagents, N-phosphonyl imines.
