Resetting the body clock for people who work at night
The problem
Night and rotating shift work is common across healthcare, manufacturing, and transportation. It forces the body's internal clock out of step with the work schedule, and many shift workers struggle with poor sleep, daytime fatigue, and higher rates of metabolic and cardiovascular problems. Today's options mostly treat symptoms, like sleepiness or insomnia, without correcting the underlying misalignment.
Our approach
Every cell keeps time with a network of clock proteins that switch genes on and off over roughly 24 hours. Tidewell is developing oral small molecules that adjust the timing of this molecular clock. The goal is a once-daily medicine that helps shift workers move their internal clock to match their schedule, rather than fighting it.
Progress to date
- Lead series shifts clock timing in human cell reporter assays in a dose-dependent way (illustrative)
- Favorable early oral exposure in rodents (illustrative)
- Provisional patent application filed on the lead chemical series (illustrative)
Why now
Advances in circadian biology have mapped the clock's core proteins in detail, making them tractable drug targets. Growing awareness of shift-work health effects is creating demand from employers and health systems.
