Lundbeck A/S (Lundbeck) announced today that the U.S. Food and Drug Administration (FDA) has accepted the submission of a New Drug Application (NDA) for BrintellixTM (vortioxetine) for the treatment of major depressive disorder (MDD) in adult patients. Brintellix (pronounced “brin′-tel-ix”) is the proposed global trade name for vortioxetine. According to the timelines established by the Prescription Drug User Fee Act (PDUFA), the review of the NDA is targeted for completion by 2 October, 2013. The NDA includes positive data from six short-term studies and one long-term maintenance study. The vortioxetine global clinical development program included more than 7,500 individuals aged 18 to 88 years old exposed to the drug. Major depression, often referred to as depression, is a common, debilitating illness affecting around 15 million Americans and 121 million people worldwide. Depression was the third leading contributor to the global burden of disease in 2004 and is projected to be the leading contributor to the worldwide burden of disease by 2030. -
New Developments in Prokinetic Therapy for Gastric Motility Disorders
REVIEW published: 24 August 2021 doi: 10.3389/fphar.2021.711500 New Developments in Prokinetic Therapy for Gastric Motility Disorders Michael Camilleri* and Jessica Atieh Clinical Enteric Neuroscience Translational and Epidemiological Research (CENTER), Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN, United States Prokinetic agents amplify and coordinate the gastrointestinal muscular contractions to facilitate the transit of intra-luminal content. Following the institution of dietary recommendations, prokinetics are the first medications whose goal is to improve gastric emptying and relieve symptoms of gastroparesis. The recommended use of metoclopramide, the only currently approved medication for gastroparesis in the United States, is for a duration of less than 3 months, due to the risk of reversible or irreversible extrapyramidal tremors. Domperidone, a dopamine D2 receptor antagonist, is available for prescription through the FDA’s program for Expanded Access to Investigational Drugs. Macrolides are used off label and are associated with tachyphylaxis and variable duration of efficacy. Aprepitant relieves some symptoms of gastroparesis. There are newer agents in the pipeline targeting diverse gastric (fundic, antral and pyloric) motor functions, including novel serotonergic 5-HT4 agonists, dopaminergic D2/3 antagonists, neurokinin NK1 antagonists, and ghrelin agonist.

The main etiologies are diabetes, idiopathic and post- gastric and esophageal surgical settings. The management of gastroparesis is challenging due to a limited number of medications and patients often have symptoms, which are refractory to available medications.

GPCR/G Protein
Inhibitors, Agonists, Screening Libraries www.MedChemExpress.com GPCR/G Protein G Protein Coupled Receptors (GPCRs) perceive many extracellular signals and transduce them to heterotrimeric G proteins, which further transduce these signals intracellular to appropriate downstream effectors and thereby play an important role in various signaling pathways. G proteins are specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP). In unstimulated cells, the state of G alpha is defined by its interaction with GDP, G beta-gamma, and a GPCR. Upon receptor stimulation by a ligand, G alpha dissociates from the receptor and G beta-gamma, and GTP is exchanged for the bound GDP, which leads to G alpha activation. G alpha then goes on to activate other molecules in the cell. These effects include activating the MAPK and PI3K pathways, as well as inhibition of the Na+/H+ exchanger in the plasma membrane, and the lowering of intracellular Ca2+ levels. Most human GPCRs can be grouped into five main families named; Glutamate, Rhodopsin, Adhesion, Frizzled/Taste2, and Secretin, forming the GRAFS classification system. A series of studies showed that aberrant GPCR Signaling including those for GPCR-PCa, PSGR2, CaSR, GPR30, and GPR39 are associated with tumorigenesis or metastasis, thus interfering with these receptors and their downstream targets might provide an opportunity for the development of new strategies for cancer diagnosis, prevention and treatment. At present, modulators of GPCRs form a key area for the pharmaceutical industry, representing approximately 27% of all FDA-approved drugs. References: [1] Moreira IS.

Zhangb, Gregory Dussora, Theodore J. Pricea,* from https://journals.lww.com/pain Abstract Molecular neurobiological insight into human nervous tissues is needed to generate next-generation therapeutics for neurological disorders such as chronic pain. We obtained human dorsal root ganglia (hDRG) samples from organ donors and performed RNA- sequencing (RNA-seq) to study the hDRG transcriptional landscape, systematically comparing it with publicly available data from by BhDMf5ePHKav1zEoum1tQfN4a+kJLhEZgbsIHo4XMi0hCywCX1AWnYQp/IlQrHD3mH5nK33R3Qh4f27oe7zFUUf7ZAUK5aCsyqAeT54jiDxP7ZjumT3TrA== a variety of human and orthologous mouse tissues, including mouse DRG (mDRG). We characterized the hDRG transcriptional profile in terms of tissue-restricted gene coexpression patterns and putative transcriptional regulators, and formulated an information-theoretic framework to quantify DRG enrichment. Relevant gene families and pathways were also analyzed, including transcription factors, G-protein-coupled receptors, and ion channels. Our analyses reveal an hDRG-enriched protein-coding gene set (;140), some of which have not been described in the context of DRG or pain signaling. Most of these show conserved enrichment in mDRG and were mined for known drug–gene product interactions. Conserved enrichment of the vast majority of transcription factors suggests that the mDRG is a faithful model system for studying hDRG, because of evolutionarily conserved regulatory programs.
