Oxygen-Driven Atom Transfer Radical Polymerization.

In traditional atom transfer radical polymerization (ATRP), oxygen must be meticulously eliminated due to its propensity to quench radical species and halt the polymerization process. Additionally, oxygen oxidizes the lower-valent Cu catalyst, compromising its ability to activate alkyl halides and propagate polymerization. In this study, we present an oxygen-driven ATRP utilizing alkylborane compounds, a method that not only circumvents the need for stringent oxygen removal but also exploits oxygen as an essential cofactor to promote polymerization.

Background: Oxidative stress is strongly linked to neurodegeneration through the activation of c-Abl kinase, which arrests α-synuclein proteolysis by interacting with parkin interacting substrate (PARIS) and aminoacyl tRNA synthetase complex-interacting multifunctional protein 2 (AIMP2). This activation, triggered by ataxia-telangiectasia mutated (ATM) kinase, leads to dopaminergic neuron loss and α-synuclein aggregation, a critical pathophysiological aspect of Parkinson's disease (PD). To halt PD progression, pharmacological inhibition of c-Abl kinase is essential.

Interferon types-I/II (IFN-αβ/γ) secretions are well-established antiviral host defenses. The human immunodeficiency virus (HIV) particles are known to prevail following targeted cellular interferon secretion. CD4 T-lymphocytes are the primary receptor targets for HIV entry, but the virus has been observed to hide (be latent) successfully in these cells through an alternate entry route via interactions with LFA1.

Type 2 diabetes (T2D) is increasing relentlessly globally, affecting ever younger patients. Many T2D patients do not attain glycemic target levels, indicating a clear need for novel antihyperglycemic drugs. Ideally, these should not only control glycemia, but also halt or slow the progressive loss of beta cells.

Limited treatment options are available for bladder cancer (BCa) resulting in extremely high mortality rates. Cyclovirobuxine D (CVB-D), a naturally alkaloid, reportedly exhibits notable antitumor activity against diverse tumor types. However, its impact on CVB-D on BCa and its precise molecular targets remain unexplored.
