Aging Clocks Applied to Human Trial Data Support AI-Designed Drug Lowering Age

Six proteomics-based aging clocks (age assessments from large-scale analyses of proteins) agreed that patients treated with the AI-designed drug rentosertib appeared younger.

The AI-designed drug rentosertib was shown to lower biological age across six aging clocks in patients with idiopathic pulmonary fibrosis.

Model: 20-month-old female C57BL/J mice 
Dosage: 10 nmol/kg/day of semaglutide

Semaglutide extends mouse lifespan and targets signs of aging, such as diminished NAD+, while mimicking the anti-aging effects of caloric restriction (consuming fewer calories). 


The study was led by Dr. Danica Chen (image: berkeley.edu). 

Model: 6-week-old ICR mice
Dosage: 250 mg/kg per day or 500 mg/kg per day of glucosamine and 100 mg/kg per day or 200 mg/kg per day of aspirin for either eight (acute alcohol exposure model) or 40 days (chronic alcohol exposure model)

New Study Supports Repurposing Glucosamine Against Liver Aging

A sugar-like compound found in cartilage called glucosamine reduces dysfunctional cells (senescent cells) in the liver and attenuates liver damage from alcohol consumption in mice.

Glucosamine alleviates liver damage from alcohol consumption in mice, supporting its potential for use against alcoholic liver disease.

Model: Male C57BL/6J (B6) mice (15 months old at the start of treatment)
Dosage: Approximately 5 mg/kg/day of S-1-propenyl-L-cysteine (S1PC) was administered orally for 8 months, from 15 to 23 months of age. S1PC was given in chow containing 0.0025% S1PC, with a second experiment using drinking water to confirm the findings.

Researchers found that a compound found in garlic supports healthier muscle aging by boosting cellular defenses linked to longevity and maintaining physical performance.
