Antinociceptive and Anti‐inflammatory Effect of Nicandrin B Isolated From Datura ferox in Zebrafish

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Nicandrin B (Nic B), a withanolide isolated from Datura ferox leaves, was investigated for its antinociceptive and anti‐inflammatory effects in adult zebrafish (Danio rerio). Animals treated with Nic B (4, 20, and 40 mg/kg) showed no toxicity and maintained normal locomotor activity.

Shifting the Substrate Scope of an Ene/Yne‐Reductase by Loop Engineering

open access: yesChemCatChem, EarlyView.
A flexible active‐site loop that is involved in shaping the substrate and product cleft as well as the active‐site pocket was identified for the MDR‐related ene/yne‐reductase CaeEnR1 from Cyclocybe aegerita. Double mutations of this loop showed an up to 20‐fold increase in conversion rates toward cinnamaldehyde‐like substrates and a 2‐fold increase in ...

Cutting‐Edge Aptasensing Approaches for Electrochemical Detection of Exosomes Utilizing MXenes

open access: yesChemElectroChem, EarlyView.
This work notably summarizes research on 2D MXenes/MXene's‐hybrid‐based nanoplatforms patterned with aptamers as an alternative to antibodies affording highly sensitive and robust biosensing of exosomes as well as their efficient isolation. The exosomes are highlighted as a valuable source of biomarkers and with the immobilization approaches of ...
