MedKoo CAT#: 319930

CAS#: 194085-75-1 (S-isomer)

Description: Carisbamate, also known as JNJ-10234094, RWJ 333369 and YKP-509, is an antiepileptic candidate. Carisbamate has powerful disease-modifying effects in the lithium-pilocarpine model of temporal lobe epilepsy. Carisbamate inhibits glutamate transmission in the granule cell of the dentate gyrus. Carisbamate acutely suppresses spasms in a rat model of symptomatic infantile spasms.

More Info: On October 24, 2008, Johnson & Johnson announced that it had submitted a New Drug Application to the U.S. Food and Drug Administration (FDA) for carisbamate. Carisbamate has received provisional approval by the FDA to be marketed under the brand name of Comfyde. However, on August 21, 2009, Johnson & Johnson reported that the FDA had failed to give marketing approval. (https://en.wikipedia.org/wiki/Carisbamate).
