The present invention provides a topiramate immunoassay and reagents for use in the immunoassay. In particular, topiramate is derivatized at the sulfamate moiety or the 9-carbon or 10-carbon methyl group of topiramate to add a label bound directly or through a linking group for use as a tracer (competitive analyte analog) or to add a linking group bound to a carrier for use as an immunogen to induce anti-topiramate antibodies. Immunoassay methods and kits are also provided.
The present invention is directed to novel compounds of the formula (I) ##STR00001## wherein X, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are as described in the specification, processes for the preparation of and pharmaceutical compositions comprising said derivatives. The compounds of the present invention are useful for the treatment of epilepsy. The invention is further directed to a process for the preparation of compounds of formula (XX), ##STR00002## wherein X, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are as described in the specification.
