Think Beyond The Core: Computationally Decoding the Hydrophilic Corona of Drug‐Loaded Polymer Micelles

Small, EarlyView.
Drug‐loaded ABA‐type triblock copolymer micelles with a hydrophobic poly(2‐n‐butyl‐2‐oxazine) core (B‐block) and hydrophilic coronas (pEG, pDMAA, pSAR (A‐block)) are investigated by all‐atom molecular dynamics simulations at 20% and 60% curcumin loadings.

The Fragmentation of 2,3-Dihydroisothiazol-3-one 1,1-Dioxide Derivatives: A Novel Cheletropic Process

CHIMIA, 1992
Adducts obtained by 1,3-dipolar cycloadditions to 2,3-dihydroisothiazol-3-one 1,1-dioxides are inclined to undergo a cheletropic process, by which the newly formed heterocyclic part undergoes aromatization, while SO2 is extruded and an ...

Peptide Terminated Polymer Brush Nanomaterials for Label‐Free Separation of Cancer Cells Based on Relative Adhesion

Small, EarlyView.
Horan et al. demonstrate that RGD peptide‐functionalized poly(ethylene glycol) brush films synthesized in polydimethylsiloxane microfluidic channels by surface‐initiated atom transfer radical polymerization enable label‐free separation of melanoma and ovarian cancer cells based on differential integrin expression.

High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Structural and mutational analysis of Methanosarcina mazei prenylated FMN synthase reveals the basis of its unique prenyl donor substrate specificity

The FEBS Journal, EarlyView.
Some prenylated flavin mononucleotide (prFMN) synthases exceptionally prefer dimethylallyl phosphate (DMAP) over dimethylallyl diphosphate (DMAPP), which is a common prenyl donor substrate for many prenyltransferases. Structural and mutagenic analyses of Methanosarcina mazei prFMN synthase, which prefers DMAP but can also accept DMAPP, elucidated its ...
