Cat.No. 2839 - Levetiracetam | C8H14N2O2 | CAS No. 102767-28-2
Description: Antiepileptic; binds SV2A
Alternative Names: Keppra, UCB L059
Chemical Name: (2S)-(2-Oxopyrrolidin-1-yl)butyramide
Purity: ≥99% (HPLC)

Biological Activity

Antiepileptic that displays distinctive properties from conventional antiepileptic drugs. Displays potent seizure protection in animal models of chronic epilepsy but lacks activity in acute seizure models. Binds synaptic vesicle protein 2A (SV2A) and inhibits Na+-dependent Cl-/HCO3- exchange.

Deuterated analog also available.

Compound Libraries

Levetiracetam is also offered as part of the Tocriscreen Plus and Tocriscreen Library of FDA-Approved Compounds. Find out more about compound libraries available from Tocris.
