TONABERSAT Chemical Properties,Usage,Production

Uses

It is a cholinesterase inhibitor for treating and preventing migraine. An antimigraine agent.

Biological Activity

migraine is a common, recurrent and primary headache disorder. optimisation of novel cis- and trans-4-(substituted-anfido)benzopyran-3-ol derivatives has led to the identification of tonabersat (sb-220453) with potential antimigraine activity.

Biochem/physiol Actions

Tonabersat (SB-220453) exhibits anticonvulsant property. It is a member of the family of novel benzoylamino-benzopyran compounds. Tonabersat is used as a therapeutic for trigeminal nerve-induced neurovascular reflexes. In addition, it acts as a putative migraine prophylactic agent containing an unique stereospecific binding site in the brain.

in vitro

topiramate targets multiple cortical and subcortical loci, altering voltage-gated ion channels and chemical transmission to decrease abnormal brain excitability. preclinical studies have identified four properties that may account for the drug’s efficacy in epilepsy and migraine prophylaxis: (i) blockage of voltage-dependent sodium channels; (ii) augmentation of the activity of the neurotransmitter g-aminobutyric acid (gaba) at some subtypes of the gaba-a receptor; (iii) antagonism of the ampa/kainate subtype of the glutamate receptor; and (iv) inhibition of the carbonic anhydrase enzymes, particularly isozymes ii and iv [1].

in vivo

tonabersat binds selectively to a unique site in the brain. moreover, tonabersat could markedly reduce cortical spreading depression (csd) and csd-associated events and inhibite gap-junction communication between neurons and satellite glial cells in the trigeminal ganglion. together, these findings indicate that tonabersat should have clinical application in preventing migraine attacks [2].
