Description: ZK-95962 is a gamma-aminobutyric acid (GABA) receptor agonist potentially for the treatment of anxiety disorders. ZK-95962 had selective effects on releasing exploratory locomotor activity suppressed by footshock (punished crossings). ZK-95962 had weak effects on the measures of anxiolytic activity. The feelings of uneasiness and myoclonic jerks, provoked by photostimulation, were also abolished by ZK-95962.

Price and Availability




ZK-95962 is not in stock, may be available through custom synthesis. For cost-effective reason, minimum 1 gram order is requested. The product will be characterized by NMR, HPLC and MS analysis. Purity (HPLC) is usually >98%. CoA, QC data, MSDS will be provided when product is successfully made. The estimated lead time is 2-3 months. Please send email to sales@medkoo.com to inquire quote.
