Certain chronic neurologic disorders, such as Parkinson's disease, are caused by an insufficiency of the neurotransmitter dopamine secondary to the degeneration of substantia nigra dopaminergic neurons. N-(α-Linolenoyl) tyrosine (NALT) is a simple α-amide conjugate between the ω-3 essential fatty acid α-linolenate and the amino acid tyrosine. α-Linolenate is an important precursor to docosahexaenoic acid (DHA), a prominent brain polyunsaturated fatty acid, while tyrosine is the metabolic precursor for neuronal dopamine synthesis. NALT was prepared as a method for enhancing central nervous system (CNS) dopamine content by facilitated transport of the tyrosine precursor across the blood-brain barrier. In experimental rat models of dopamine insufficiency, NALT increased CNS dopamine levels and exhibited an activity profile consistent with an anti-Parkinson's therapeutic agent.
5-HT7 agonist 2 is a highly potent 5-HT7 receptor agonist, exhibiting an IC50 value of 28.7 nM. This compound holds promise for studying and understanding various Central Nervous System (CNS) disorders [1].
Ganglioside GM2 is a glycosphingolipid component of cellular membranes, primarily the plasma membrane. Levels of ganglioside GM2 are elevated in the brain of patients with Sandhoff disease, as well as feline and mouse models of the disease. Ganglioside GM2 accumulates in the lysosomes of individuals with Tay-Sachs disease and GM2-activator deficiency, as well as in the CNS of patients with and animal models of mucopolysaccharide storage disorders and Niemann-Pick disease types A, C1, and C2. Ganglioside GM2 mixture contains ganglioside GM2 molecular species with C18:1 and C20:1 sphingoid backbones.
AVN-101 is a very potent 5-HT7 receptor antagonist, with slightly lesser potency toward 5-HT6, 5-HT2A, and 5HT-2C receptors. It is a multi-target drug candidate for the treatment of CNSdisorders.
R-PSOP is a potent and selective nonpeptidic NMUR2 antagonist, exhibiting binding affinity to human and rat NMUR2 with Ki values of 52 nM and 32 nM, respectively. This compound demonstrates moderate central nervous system (CNS) penetration and is valuable in the study of eating disorders, obesity, pain, and stress-related disorders [1].
