Synthesis and Fluorescent Properties of Aminopyridines and the Application in “Click and Probing”

Molecules, 2022
Unsubstituted pyridin-2-amine has a high quantum yield and is a potential scaffold for a fluorescent probe. However, the facile access to conjugated highly substituted aminopyridines and the study of their fluorescent properties is scarce. In this paper,

A near-infrared fluorescent probe for hydrogen sulfide in living cells

, 2013
Fluorescent probes for hydrogen sulfide have received considerable attention because of the biological significance of H2S recognized recently. However, near-infrared fluorescent probes for H2S are still rare.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Theoretical insights into a turn-on fluorescence probe based on naphthalimide for peroxynitrite detection

Heliyon
Compared with other reactive oxygen species, peroxynitrite (ONOO−) has diversified reactions and transformations in organisms, and its specific action mechanism is not very clear. The study of reactive oxygen species is of great significance in the field

A highly selective turn-on near-infrared fluorescent probe for hydrogen sulfide detection and imaging in living cells

, 2012
We have described a turn-on near-infrared fluorescent probe Cy-NO2 based on nitro group reduction for intracellular H2S detection. The probe employs cyanine dye as a fluorophore, and is equipped with a nitro group as a fluorescent modulator.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
