The role of soluble guanylate cyclase (GC) activator (A-350619) and inhibitor (methylene blue) was evaluated in the presence of phosphodiesterase-7 (PDE-7) inhibitor such as BRL-50481, in animal models of epilepsy. Seizures were induced in the animals by subjecting them to an injection of chemical convulsant, pentylenetetrazole (PTZ) and maximal electroshock (MES). The study mainly comprises the onset of seizures, mortality/recovery, percentage of prevention of seizures (anti-convulsant) and total duration of convulsive time. The combination of GC inhibitor, methylene blue with BRL 50481 showed a delay onset (P<0.001) in incidence of seizures, compared to A-350619 and BRL 50481 alone treated group. The total convulsive time was prolonged significantly (P<0.01) in methylene blue alone treated (69.2%) groups, compared to DMSO received group (100%). The study also demonstrates that.. View More»
