Application

Longdaysin may be used to study cell signaling that regulate the circadian clock and behavior.

Biochem/physiol Actions

Longdaysin inhibits CK1, ERK2, and CDK7 kinases in low mM concentrations. The activity of longdaysin results in a lengthening of circadian periods in cell based and in vivo systems. Transgenic zebrafish harboring a per3-luc reporter gene displayed a 10 hour lengthening of circadian period when treated with longdaysin. Longdaysin reduces the phosphorylation of PER1 the regulator of molecular clock function and manipulates the circadian clock.

Impairment of the circadian clock has been associated with numerous disorders, including metabolic disease. Although small molecules that modulate clock function might offer therapeutic approaches to such diseases, only a few compounds have been identified that selectively target core clock

Circadian clocks are present in nearly all tissues of an organism, including the brain. The brain is not only the site of the master coordinator of circadian rhythms located in the suprachiasmatic nuclei (SCN) but also contains SCN-independent oscillators that

Circadian rhythms in cartilage homeostasis are hypothesized to temporally segregate and synchronize the activities of chondrocytes to different times of the day, and thus may provide an efficient mechanism by which articular cartilage can recover following physical activity. While the

The circadian clock underlies daily rhythms of diverse physiological processes, and alterations in clock function have been linked to numerous pathologies. To apply chemical biology methods to modulate and dissect the clock mechanism with new chemical probes, we performed a
