Quantitative structure activity relationships in 1-substituted ureidophenoxy-3-amino-2-propanols, a class of beta adrenergic blocking agents

open access: yes, 1980
The β-adrenergic blocking potency of 56 1-substituted ureidophenoxy-3-amino-2-propanols has been analysed in terms of the linear Free-Wilson model.

Frustrated Lewis Pairs and Metallic Ni Synergistically Enabled Low‐Temperature Hydrogenolysis of Lignin Models

open access: yesAdvanced Science, EarlyView.
Nickel–aluminum composite oxide (NiAlOx‐300) derived from NiAl layered double hydroxide showed high activity for hydrogenolysis of various lignin models. Especially, hydrogenolysis of benzyl phenyl ether could be efficiently proceeded at 20°C and 1 MPa H2.

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

Generative AI‐Driven Accelerated Discovery of Passivation Molecules for Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
A generative artificial intelligence (AI) framework combining a discriminative machine learning model (SMILES‐X) and a generative language model (GPT‐2) autonomously discovers new molecular passivators for perovskite solar cells (PSCs). Through an iterative design loop, over 100 000 candidates are generated and screened, and randomly selected molecules

Brain and Liver Dual‐Targeting Oridonin Nanoparticles to Enhance Aβ Clearance for Alzheimer's Disease Therapy

open access: yesAdvanced Science, EarlyView.
We developed a nanoparticle named OAF, which simultaneously targeted to both the brain and liver via the transferrin receptor 1 (TfR1) receptor, promoting lipoprotein receptor‐related protein 1 (LRP1) expression to enhance amyloid‐beta (Aβ) clearance. In AD mice model, OAF significantly reduced Aβ deposition and cognitive impairment, while a mitigating

The viscosity of dilute aqueous solutions of aliphatic alcohols

open access: yes, 1982
Relative viscosities have been measured of dilute aqueous solutions of aliphatic alcohols, including methanol, ethanol, the propanols, the butanols and the pentanols, at temperatures of 278, 293 and 313 K at concentrations in the range 10-4-10-2 mol dm-3.

On the dehydrogenation of 1- and 2-propanols on Cu(111) surface: A UBI-QEP based approach

open access: yes, 2004
2049-2054The method of unity bond index-quadratic exponential potential (UBI-QEP) has been employed to investigate the energetics of routes to adsorption and decomposition of 1- and 2-propanols on Cu(111) plane.

Formation of single diastereomers of β-hydroxy sulfoxides by biotransformation of β-ketosulfides using Helminthosporium species NRRL 4671

open access: yes, 2002
Single biotransformations of 1-(phenylthio)-2-propanone and 1-(p-methoxyphenylthio)-2-propanone by the fungus Helminthosporium species NRRL 4671 resulted in both sulfur oxidation to the sulfoxide and carbonyl reduction to the alcohol. The corresponding (

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

open access: yesAdvanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.
