详细说明

Sigma Aldrich - W2145

Biochem/physiol Actions
C28-steroidal lactone that can induce nerve development and improve nervous system function. Potential therapeutic for neurologic disorders like Alzheimer’s and Parkinson’s disease.1 In primary rat cortical neurons, withanolide A significantly up-regulated IDE levels, a prominent enzyme involved in degrading amyloid β protein, which may help to clear excess amyloid β protein from an Alzheimer′s-inflicted brain.2
