MedKoo Cat#: 527409 | Name: Caprospinol

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Caprospinol, also known as SP-233, is a β-Amyloid (Aβ) protein neurotoxicity inhibitor potentially for the treatment of Alzheimer's disease. Caprospinol crosses the blood-brain barrier, accumulates in the brain, and restores cognitive impairment in a pharmacological rat model of AD. Caprospinol is stable, does not bind to known steroid receptors, is devoid of mutagenic and genotoxic properties, and is devoid of acute toxicity in rodents.
