A range of neurological disorders, including epilepsy and dystonia, may involve dysfunctional intracortical inhibition, and may respond to treatments that modify it. Parkinson’s is a neurodegenerative disease characterized by increased activity of GABA in basal ganglia and the loss of dopamine in nigrostriatum, associated with rigidity, resting tremor, gait with accelerating steps, and fixed inexpressive face. Neurological deficits, along with neuromuscular involvement, are characteristic of mitochondrial disease, and these symptoms can have a dramatic impact on patient quality of life. Neurological features may be manifold, ranging from neural deafness, ataxia, peripheral neuropathy, migraine, seizures, stroke‐like episodes and dementia and depend on the part of the nervous system affected.

    Galantide 138579-66-5 98%
    Galantide, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide recognizes two classes of galanin binding sites (KD<0.1 nM and ~6 nM) in the rat hypothalamus. Galantide dose dependently (IC50=1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide appears to bind to a single population of SP receptors (KD~40 nM).
