Rewiring mTOR signaling in Alzheimer's disease: emerging mTOR modulators beyond oncology.
Lohnes BJ, Myskova A, Tyagi A, Hartwig UF, Poddar NK
Medicinal Plants
Dozens of the most promising experimental Alzheimer's drugs trace their chemical blueprints to marine organisms and medicinal plants — the same botanical diversity that herbalists and ethnobotanists have catalogued for centuries.
Alzheimer's disease and cancer, though very different, share a broken molecular switch inside cells that controls growth and waste-cleanup. Scientists looked at 37 substances — many originally developed for cancer — that can reset this switch, including compounds originally found in plants and sea creatures. They found that plant-based compounds have rich, complex effects but are hard for the body to absorb, while lab-made drugs are precise but sometimes get outsmarted by the cell; the best hope is blending both approaches.
Key Findings
37 mTOR-modulating compounds were systematically reviewed as potential Alzheimer's treatments, many originally developed for oncology.
Plant- and marine-derived natural products show pleiotropic (multi-target) benefits but are limited by poor pharmacokinetics including low blood-brain barrier penetration.
The authors conclude that combining natural product scaffolds with targeted synthetic engineering offers the most promising path forward, enabling nuanced mTOR network modulation rather than blunt pathway inhibition.

Researchers reviewed 37 compounds that target a cellular growth-control pathway (mTOR) shared by both cancer and Alzheimer's disease, finding that combining plant-derived natural compounds with engineered synthetic drugs may offer a smarter treatment strategy than either approach alone.

While Alzheimer's disease (AD) is the most common cause of dementia, curative treatments remain unavailable. Despite distinct pathologies between AD and cancer, shared dysregulation of the PI3K-AKT...

Ethnobotany is the interdisciplinary study of how humans use, manage, and perceive plants across different cultures, drawing on knowledge from botany, anthropology, ecology, and chemistry. It matters for plant science because it documents traditional ecological knowledge that can reveal previously
