We reported for the first time that ethyl bromodifluoroacetate directly reacts with azaindole without transition metal catalysis to produce a difluoromethyl protected 5‐aldehyde group product in one step. It is worth mentioning that the reacted aldehyde group is only formed at the 5 position. In addition, this method has good substrate applicability and functional group tolerance. Finally, we also...
Objective
To explore the function of circular RNA IQ motif‐containing GTPase‐activating protein 1 (circ‐IQGAP1) in interleukin (IL)‐1β‐induced osteoarthritis (OA) model and to explore whether circ‐IQGAP1 can modulate microRNA‐671‐5p (miR‐671‐5p) and transcription factor 4 (TCF4) to regulate chondrocyte apoptosis, inflammatory injury, and extracellular matrix degradation.
Methods
The cartilage tissues...
