Assembly of (hetero)aryl sulfilimines via copper-catalyzed enantioselective S-arylation of sulfenamides with (hetero)aryl Iodides

Nature Communications
The (hetero)aryl sulfoximines are important structures for developing bioactive molecules, whose synthesis relies on oxidation of (hetero)aryl sulfilimines. However, asymmetric approaches for assembling (hetero)aryl sulfilimines are still rare.

The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1

FEBS Letters, EarlyView.
MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

Evaluation of an enzyme-linked immunoelectrotransfer blot test for the confirmatory serodiagnosis of human toxocariasis

Memorias do Instituto Oswaldo Cruz, 2009
To improve the serodiagnosis of human toxocariasis, a sensitive and specific enzyme-linked immunoelectrotransfer blot (EITB-IgG) test was developed and evaluated using Toxocara canislarvae excretory-secretory antigens for detecting anti-Toxocara IgG ...

Proton capture cross section of Sr isotopes and their importance for nucleosynthesis of proton-rich nuclides [PDF]

, 2001
The (p,$\gamma$) cross sections of three stable Sr isotopes have been measured in the astrophysically relevant energy range. These reactions are important for the $p$-process in stellar nucleosynthesis and, in addition, the reaction cross sections in the

Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation

FEBS Letters, EarlyView.
The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.
