Singlet Oxygen Photooxidation of Peptidic Oxazoles and Thiazoles.

Journal of Organic Chemistry, 2019
Oxazoles and thiazoles are commonly found moieties in nonribosomal peptides (NRPs) and ribosomally synthesized post-translationally modified peptides (RiPPs), which are important biomolecules present in the environment and in natural waters.

Second-generation nitazoxanide derivatives: thiazolides are effective inhibitors of the influenza A virus [PDF]

, 2018
Aim: The only small molecule drugs currently available for treatment of influenza A virus (IAV) are M2 ion channel blockers and sialidase inhibitors. The prototype thiazolide, nitazoxanide, has successfully completed Phase III clinical trials against ...

MARPLE: A Proximity‐Triggered CRISPR‐Cas13 Platform for Ultrasensitive Antibody Detection

Advanced Science, EarlyView.
MARPLE is a modular CRISPR‐Cas13 immunoassay that uses antibody‐induced proximity to trigger a toehold‐exchange reaction, releasing an RNA activator for Cas13. This one‐pot, isothermal architecture enables ultrasensitive (femtomolar) and highly specific detection of diverse antibodies, including therapeutic, pathogen‐specific, and cancer‐associated ...

Bioactive thiazole and benzothiazole derivatives

European Journal of Medicinal Chemistry, 2015
The heterocycles are the versatile compounds existing in almost all natural products and synthetic organic compounds, usually associated with one or the other biological activity. Among the heterocycles the thiazoles and benzothiazoles occupy a prominent position.

Methylation‐Induced Permanent Charge Polarization in Covalent Organic Frameworks for Visible Light‐Driven Water Decontamination and Disinfection

Advanced Science, EarlyView.
A targeted in situ methylation strategy is developed to engineer cationic centers in a quinoline‐linked COF (NQ‐COFS1‐Me), creating a strong built‐in electric field, which effectively suppresses excitonic effects and promotes charge separation. The optimized material demonstrates powerful photocatalytic ROS generation for rapid bacterial inactivation ...
