A variety of pathological conditions exhibit profound day-night changes in the symptom intensity with a large portion exacerbating and occurrence of grave events. Recent developments in our understanding of circadian biology and the availability of tools to characterize the molecular clock indicate that the choosing appropriate dosing time have consequences for the efficacy and safety of new and existing therapeutic drugs. Progression of this research field also suggests that many pathological conditions are under the control of the circadian clock. These notions reveal opportunities for new therapeutic strategies. Now novel therapeutic approaches are facilitated by development of chemical probes and synthetic ligands targeted to an increasing number of the key proteins that causing circadian exacerbation of pathological events. .

Recent developments in our understanding of circadian biology and the availability of tools to characterize this oscillation system indicate that the choosing appropriate dosing time have consequences for the ef cacy and safety of new and existing therapeutic drugs (Chronopharmacotherapy). Progression of this research eld also suggests that many pathological conditions are under the control of the circadian clock. These notions reveal opportunities for new therapeutic strategies. Now novel therapeutic approaches are facilitated by development of chemical probes and synthetic ligands targeted to an increasing number of the key proteins that causing circadian exacerbation of pathological events.
The major objective of our research is to understand the molecular mechanisms for day-night changes in the pathological events and the impact of circadian rhythms on the onset of diseases. Based on these mechanism, we attempt to identify new therapeutic target and to develop novel strategy for treatment of diseases.
