1. Alpha-methyltryptophan, on administration to experimental animals gives rise to cerebral alpha-methylserotonin, which substitutes for serotonin in certain behavioral and functional tests. 2. Such results are consistent with the similarity of the properties of the two indoleamines with respect to
In the non-amyloidogenic pathway the alpha-secretase cleaves the amyloid precursor protein (APP) within the sequence of Abeta-peptides and precludes their formation. In addition, alpha-secretase cleavage releases an N-terminal extracellular domain with neurotrophic and neuroprotective properties.
Several variants of interferon-alpha (IFN-alpha) were isolated and purified to homogeneity. They differed to various degrees in biological properties. However, three IFN-alpha 2 variants showed only minor differences from a variant called IFN-alpha 88 with regard to their ability to inhibit growth
Parkinson's disease is a progressive age-related neurodegenerative disease with invariant loss of substantia nigra dopamine neurons and striatal projections. This disorder is well known for the associated motoric symptoms including resting tremor and the inability to initiate movement. However, it
Alpha-mannosidosis (α-mannosidosis) is a rare lysosomal storage disorder with an autosomal recessive inheritance caused by mutations in the gene encoding for the lysosomal α-d-mannosidase. So far, 155 variants from 191 patients have been identified and in part characterized at the biochemical level.
Novel 2,3-benzodiazepine and related isoquinoline derivatives, substituted at position 1 with a 2-benzothiophenyl moiety, were synthesized to produce compounds that potently inhibited the action of GABA on heterologously expressed GABAA receptors containing the alpha 5 subunit (GABAA α5), with no
Approximately 5% to 10% of patients with asthma have severe disease that is refractory or poorly responsive to inhaled corticosteroid therapy. These patients represent an important unmet clinical need because they experience considerable morbidity and mortality and consume a disproportionately large
Fabry disease (FD, OMIM 301500) is an X-linked inherited disorder of metabolism due to mutations in the gene encoding alpha-galactosidase A, a lysosomal enzyme. The enzymatic defect leads to the accumulation of neutral glycosphingolipids throughout the body, particularly within endothelial cells.
