Researchers at F. Hoffmann-La Roche Ltd. and Hoffmann-La Roche Inc. have synthesized radiolabeled compounds acting as GABA(A) receptor subunit α2β2γ1 (GABRA2) positive allosteric modulators acting as positron-emission tomography (PET) and autoradiography imaging agents reported to be useful for the diagnosis of neurological disorders.
Aberrant NLRP3 inflammasome activation is at the root of a wide number of conditions, from heart, gastrointestinal, kidney or liver disorders to neuroinflammatory diseases such as Parkinson’s disease or multiple sclerosis. Researchers from Nodthera Ltd. have reported on NT-0796, an NLRP3 inflammasome inhibitor with an in vivo brain penetration profile.
MicroRNAs (miRNAs) play an important role in modulating neuronal stress responses, but their impact on neuroprotection has been poorly studied. Multiple sclerosis (MS) is the most common inflammatory disease affecting the central nervous system. Researchers have recently attempted to identify potential miRNAs that play a protective role in neuroinflammation.
The U.S. FDA put out a safety warning Nov. 28 that antiseizure drugs levetiracetam and clobazam can cause a rare but serious hypersensitivity drug reaction that may start as a rash but can progress to injure internal organs. In addition, U.K. health care providers are being told to get a plan in place now to implement the first phase of the Medicines and Healthcare products Regulatory Agency’s new regulatory measures to reduce the risks of valproate, a treatment for epilepsy and bipolar disorder.
For the second time this week, a contract research organization has come under fire for trial-conduct issues – criticism leveled most recently by Biovie Inc., which saw its shares (NASDAQ:BIVI) tumble $3.03, or 60%, to end Nov. 29 at $1.96 on missed-endpoint data from the phase III trial testing Alzheimer’s disease prospect NE-3107. The data fell short of statistical significance due to site exclusions caused by what Biovie said were “significant good clinical practice violations and protocol deviations.”
Shanghai Institute of Organic Chemistry has described oleanamide derivatives acting as Kelch-like ECH-associated protein 1 (KEAP1)/nuclear factor erythroid 2-related factor 2 (NFE2-related factor 2; NFE2L2; NRF2)/antioxidant response element (ARE) pathway activators reported to be useful for the treatment of amyotrophic lateral sclerosis, diabetes, multiple sclerosis, renal disorders, Huntington's disease, Parkinson's disease, autoimmune disease and Alzheimer's disease, among others.
DE Shaw Research LLC has identified transient receptor potential cation channel subfamily A member 1 (TRPA1) antagonists reported to be useful for the treatment of pain, fibrosis, autoimmune disease, neurological, dermatological, cardiovascular, respiratory and gastrointestinal disorders, among others.
Researchers from Centre National de la Recherche Scientifique, Inserm, Université Claude Bernard and Université Jean Monnet have synthesized peptides acting as amyloid-β (Aβ) protein aggregation inhibitors reported to be useful for the treatment of amyotrophic lateral sclerosis, cerebral amyloid angiopathy, Down syndrome, Parkinson's disease, Alzheimer's disease and motor neuron disease.
Researchers from Nagoya City University presented the development of a new mouse model with cholinergic dysfunction and amyloid pathogenesis for Alzheimer's disease.
A mouse line with severe haploinsufficiency of about 92% reduction in coiled-coil and C2 domain-containing protein 1A (CC2D1A) expression was generated by breeding of Cc2d1a-knockout allele with C2d1a -/V5-HA mice to generate a compound heterozygous murine model of autism spectrum disorder (ASD).
