Anticonvulsant agents felbamate

Scheme 15.1 Postulated bioactivation pathways of the anticonvulsant agent felbamate rational chemical approach to circumvent bioactivation by fluorofelbamate.

A review of the second-generation anticonvulsants reveals that screening or serendipity led to the development of felbamate (10), 1am-otrigine (11), zonisamide (13), topiramate (15), and levetiracetam (16) on the other hand, clobazam (4d) and oxcarbazepine (12) were developed by structural variation of known agents (78). Only three, vigabatrin (8), gabapentin (9), and tiagabine (14), were developed by mechanism-based rational development (78).
