Senescent cell removal, insulin signaling inhibition/caloric restriction, and rapamycin (mTOR inhibition) extend lifespan in mice the most in our meta-analysis of over 100 different aging interventions. Surprisingly, the natural molecule fisetin simultaneously address all three, offering great promise as a therapeutic.

Magnetic nanoparticles (MNPs) can serve as a vehicle after coating to conduct targeted delivery of dissolved fisetin to improve bioavailability.

Fisetin has low bioavailability and is quickly cleared from the body, limiting its effectiveness. Due to its excellent safety profile, clinical trials using large doses of fisetin are currently underway in hopes it can help in human aging despite these drawbacks. At ETTA, we are trying a different way. Our proprietary metal core nanoparticles can deliver fisetin, as well as other small molecules, RNA, DNA, and proteins, to treat a wide range of diseases.
