Abstract

Studies have shown that compounds from natural products, such as plant extracts or arthropods venoms are potential antioxidants, anxiolytics, anticonvulsants and antidepressants agents. Compounds from extracts are true "chemical weapons" which have different pharmacological effects on various biological systems. For instance, many of these natural products are neurotoxins with specificity and affinity for nervous tissue. These can act on receptors and transporters, or they targeted selectively on ligand- or voltage-dependent ion channels present in the neuronal membrane of invertebrates and vertebrates. Natural products are tools that can help in the understanding of neuropathological alterations in neurotransmission in humans, relating to diseases such as epilepsy, Parkinson's disease, ischemia, glaucoma, etc. Nevertheless, the potential clinical use of isolated components from natural products is poorly exploited. From another standpoint, new isolation techniques, purification and synthesis of natural products can provide a new generation of bioactive substances that could be available as feasible tools in scientific research, and especially for the development of new therapies. The development of therapeutics for neuropathologies is undoubted, further the challenge search the knowledge in neuroscience and understanding of brain diseases, which can occur with use of new bioactive toxins. The aim of the present study is to investigate the effects of the extract of the Hyptis fruticosa and Lippia grata plants, and Dinoponera quadriceps ant venom in animal models of epilepsy and Parkinson's disease.
