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.
Tonabersat is a potent inhibitor of neuronal-glial gap junctions in trigeminal ganglion that inhibits cortical spreading depression (CSD) and neurogenic inflammation in animal models of migraine.

Cancer-associated fibroblasts (CAFs) perform diverse roles and can modulate therapy responses1. The inflammatory environment within tumours also influences responses to many therapies, including the efficacy of oncolytic viruses2; however, the role of CAFs in this context remains unclear. Furthermore, little
