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.

Carbodiimides (R-N=C=N-R) are well-known intermediates for the preparation of a variety of N-containing compounds, including heterocycles and amide linkages. Be-cause of their high reactivity and easy availability, carbodiimides have been broadly used as building blocks in the synthesis of structurally complex and diverse heterocyclic com-pounds in multi-component reactions (MCRs). Recent advances in diversity-oriented syn-thesis with carbodiimide-based MCRs are discussed in this minireview and are classified into different sections based on the key transformation involved in the reactions, such as heteroannulation and nucleophilic addition reactions which containing metal-catalyzed re-actions, multi-component reactions, and catalyst-free reactions subsections.

This study has developed a pressure sensor array based on four functionalized DNA-nanoenzymes with catalase-like activity for multiple detections of foodborne pathogens through a portable pressure manometer. Benefiting from functionalization of 4-mercaptophenylboronic acid and β-mercaptoethylamine, the diversity of nonspecific interactions between four DNA-nanoenzymes and each of the nine bacteria leads to differences in pressure response patterns by catalyzing HO to generate exclusive "fingerprints". As effective statistical tools for processing multivariate data, principal component analysis and hierarchical clustering analysis are employed to identify nine foodborne pathogens by analyzing pressure response patterns.
