The Nobel Committee announced today that it has awarded the 2025 Nobel Prize in Physiology or Medicine to three scientists for their discovery of regulatory T cells, which are a critical part of the way the body prevents autoimmune attacks.
Astrazeneca AB has patented new proprotein convertase subtilisin/kexin-type 9 (PCSK9) inhibitors reported to be useful for the treatment of cardiovascular disorders.
Mitochondrial glutaminase kidney isoform (GLS, GLS1) inhibitors have been detailed in a Sitryx Therapeutics Ltd. patent. They are described as potentially useful for the treatment of fibrosis and inflammatory disorders.
Humanwell Pharmaceutical US Inc. has disclosed new potassium voltage-gated channel subfamily KQT member 2 (KCNQ2; Kv7.2) and Kv7.3 activators. They are described as potentially useful for the treatment of epilepsy, pain, depression, bipolar disorder, amyotrophic lateral sclerosis and neurodegeneration.
Work at Aligos Therapeutics Inc. has led to the discovery of new programmed cell death 1 (PDCD1; PD-1; CD279)/PD-1 ligand 1 (PD-L1; CD274) interaction inhibitors reported to be useful for the treatment of hepatocellular carcinoma and hepatitis B.
Blossomhill Therapeutics Inc. have identified 7-azaindazole macrocycles acting as ALK tyrosine kinase receptor (mutant) inhibitors potentially useful for the treatment of cancer.
Recent evidence in atopic dermatitis (AD) points to the involvement of additional pro-inflammatory pathways besides core Th2 responses. Current therapeutic approaches that work target mostly the IL-4/IL-13 pathway, but the duration of response and depth could be improved.
Hypertension is a frequent chronic condition commonly affecting the elderly, but its incidence is increasing among younger individuals. The estimates predict that 1.28 billion individuals aged 30-79 are currently living with hypertension worldwide. Despite the availability of effective treatments, monotherapy often leads to resistance and the management of adverse effects remains cumbersome.
Activation of cannabinoid receptors in the peripheral nervous system may help treat inflammatory and gastrointestinal disorders as well as pain, and several full agonists have been reported but they present safety concerns. Partial agonists, such as those that activate receptors to 20%-50% of full activity, may be safer, yet so far such agonists have emerged serendipitously.
In an isomerization reaction, uridine is modified to pseudouridine, the most abundant RNA modification which presents an extra hydrogen bond donor, altering the RNA structure and providing unique chemical properties.
