Summary
Photoswitchable prosthe6 compounds restored light-driven behavior in blind mice with AMD- and RP-like retinal degeneration, with visual responses returning after both eye-drop delivery and eye injections.
Two lead candidates—prosthe6-12 and prosthe6-15—also revived saccadic eye movements in blinded zebrafish and worked under ordinary indoor or overcast-day light without training or implanted devices.
The drugs target mGlu6 on surviving ON bipolar cells, acting as molecular prostheses that replace missing photoreceptor signals without genetic modification and with early promising safety findings.
The preclinical work, published in JACS, addresses diseases tied to photoreceptor loss that affect about 200 million people worldwide, but human testing has not started and researchers are still refining longer-lasting formulations.
If the animal results translate to people, the approach could offer a cheaper, less invasive alternative to retinal implants, mutation-specific gene therapy and other vision-restoration strategies.
