Peripherally-metallated porphyrins: meso-n1-porphyrinyl-platinum(II) complexes of 5,15-diaryl- and 5,10,15-triarylporphyrins [PDF]

open access: yes, 2002
Attempted metathesis reactions of peripherally-metallated meso-η1-porphyrinylplatinum(II) complexes such as trans-[PtBr(NiDPP)(PPh3)2] (H2DPP = 5,15-diphenylporphyrin) with organolithium reagents fail due to competitive addition at the porphyrin ring ...

Understanding and optimising the packing density of perylene bisimide layers on CVD-grown graphene

open access: yes, 2015
The non-covalent functionalisation of graphene is an attractive strategy to alter the surface chemistry of graphene without damaging its superior electrical and mechanical properties.

Ultrafast Structural Dynamics of BlsA, a Photoreceptor from the Pathogenic Bacterium Acinetobacter baumannii [PDF]

open access: yes, 2014
Acinetobacter baumannii is an important human pathogen that can form biofilms and persist under harsh environmental conditions. Biofilm formation and virulence are modulated by blue light, which is thought to be regulated by a BLUF protein, BlsA.

Synthesis and Anticancer Activity of Glucosylated Podophyllotoxin Derivatives Linked via 4β-Triazole Rings

open access: yesMolecules, 2013
A series of 4β-triazole-linked glucose podophyllotoxin conjugates have been designed and synthesized by employing a click chemistry approach. All the compounds were evaluated for their anticancer activity against a panel of five human cancer cell lines ...

A High‐Performance Zinc–Air Battery Cathode Catalyst from Recycling of Spent Lithium Iron Phosphate Batteries

open access: yesSmall Structures, 2023
A novel recycling process of the conductive agent in spent lithium iron phosphate batteries is demonstrated. Wet chemistry is applied in recovering lithium and iron phosphate, and the filter residue is calcined with a small amount of recovered iron ...

Functional differences of iodinated obestatin peptides: in vitro metabolic stability profile [PDF]

open access: yes, 2010
Peptides are small polymers of 50 amino acids, situated between organic molecules and proteins. Most peptides perform a biochemical-physical function and are therefore considered as potential drugs.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Iron-mediated Preparation of Vinylcyclopropanes. Scope, Mechanism, and Applications [PDF]

open access: yes, 2003
The addition of stabilized carbon nucleophiles to tricarbonyl(1-methoxycarbonylpentadienyl)iron(1+) cation (1a) proceeds via attack at C2 on the face of the ligand opposite the Fe(CO)3 group to generate tricarbonyl(pentenediyl)iron complexes 2. Oxidation

Hyperbranched phosphorus flame retardants: multifunctional additives for epoxy resins [PDF]

open access: yes, 2019
We successfully synthesized multifunctional P-based hyperbranched polymeric flame retardants (hb-FRs) with varying oxygen-to-nitrogen (O : N) content and characterized them via 1H and 31P NMR and GPC.
