Impact of noscapine on halting the progression of pentylenetetrazole induced kindling epilepsy in mice.
Epilepsy is caused by an excessive recurrent excitatory neuronal firing, characterized by motor, psychomotor, and sensory impairments. Current therapies fail to produce 100% outcomes because of the complexity of the disease, poor diagnosis, and upsurge to drug-resistant epilepsy. The study repurposed the drug 'noscapine' mainly known for its anti-tussive properties. For the management of epilepsy and its associated secondary complications. To confirm the effect of noscapine, adult mice were injected with pentylenetetrazole (PTZ) (35 mg/kg i.p.) on an alternate day for 29 days to induce epilepsy. Animals were pretreated with noscapine in three doses (5, 10, and 20 mg/kg i.p.) for 33 days. Various behavioural assessments like the open field test, Morris water maze, and tail suspension test were performed to observe animals' locomotor activity, spatial memory, and anxiety-depressive behaviour. On the 34th day, animals were sacrificed, and brains were removed for biochemical estimations. Prolonged PTZ treatment reduced locomotor, learning activity, and increased anxiety-depressive behaviour, which was further confirmed by reduced antioxidant levels such as reduced glutathione (GSH), superoxide dismutase (SOD), and catalase because of increased oxido-nitrosative stress, that is, malondialdehyde (MDA) and nitrite in the brain. In comparison, noscapine pretreatment attenuated PTZ-induced behavioural and biochemical changes in the animals. The results indicate that noscapine ameliorates the oxido-nitrosative stress. However, studies indicate that oxido-nitrosative stress is a significant concern for the GABAergic neurons and promotes the disease progression. Further studies are required to explore the molecular mechanism of noscapine, which might be a practical approach as a newer antiepileptic agent.

Association of Microtubule Dynamics with Chronic Epilepsy.
Approximately 30 % of epilepsy cases are refractory to current pharmacological treatments through unknown mechanisms. Much work has been done on the role of synaptic components in the pathogenesis of epilepsy, but relatively little attention has been given to the potential role of the microtubules. We investigated the level of microtubule dynamic in 30 human epileptic tissues and two different chronic epilepsy rat models. The administration of microtubule-modulating agent attenuated the progression of chronic epilepsy. By contrast, microtubule-depolymerizing agent aggravated the progression of chronic epilepsy. The electrophysiological index by whole-cell clamp was used to investigate the neuronal excitation and inhibitory synaptic transmission in brain slices after administration of microtubule-modulating agent and microtubule-depolymerizing agent. Interestingly, we found that microtubule-modulating agent significantly increased the frequency of action potential firing in interneurons, and significantly promoted the amplitudes and frequencies of miniature inhibitory postsynaptic currents. Microtubule-depolymerizing agent had an opposite effect. These findings suggest that modulating hyperdynamic microtubules may take an anti-epileptic effect via postsynaptic mechanisms in interneurons. It could represent a potential pharmacologic target in epilepsy treatment.
