Predictive QSAR Tools to Aid in Early Process Development of Monoclonal Antibodies
Predictive QSAR tools to aid in early process development of monoclonal antibodies John Micael Andreas Karlberg Published work submitted to Newcastle University for the degree of Doctor of Philosophy in the School of Engineering November 2019 Abstract Monoclonal antibodies (mAbs) have become one of the fastest growing markets for diagnostic and therapeutic treatments over the last 30 years with a global sales revenue around $89 billion reported in 2017. A popular framework widely used in pharmaceutical industries for designing manufacturing processes for mAbs is Quality by Design (QbD) due to providing a structured and systematic approach in investigation and screening process parameters that might influence the product quality. However, due to the large number of product quality attributes (CQAs) and process parameters that exist in an mAb process platform, extensive investigation is needed to characterise their impact on the product quality which makes the process development costly and time consuming. There is thus an urgent need for methods and tools that can be used for early risk-based selection of critical product properties and process factors to reduce the number of potential factors that have to be investigated, thereby aiding in speeding up the process development and reduce costs. In this study, a framework for predictive model development based on Quantitative Structure- Activity Relationship (QSAR) modelling was developed to link structural features and properties of mAbs to Hydrophobic Interaction Chromatography (HIC) retention times and expressed mAb yield from HEK cells. Model development was based on a structured approach for incremental model refinement and evaluation that aided in increasing model performance until becoming acceptable in accordance to the OECD guidelines for QSAR models. -
Metabotropic Glutamate Receptors
mGluR Metabotropic glutamate receptors mGluR (metabotropic glutamate receptor) is a type of glutamate receptor that are active through an indirect metabotropic process. They are members of thegroup C family of G-protein-coupled receptors, or GPCRs. Like all glutamate receptors, mGluRs bind with glutamate, an amino acid that functions as an excitatoryneurotransmitter. The mGluRs perform a variety of functions in the central and peripheral nervous systems: mGluRs are involved in learning, memory, anxiety, and the perception of pain. mGluRs are found in pre- and postsynaptic neurons in synapses of the hippocampus, cerebellum, and the cerebral cortex, as well as other parts of the brain and in peripheral tissues. Eight different types of mGluRs, labeled mGluR1 to mGluR8, are divided into groups I, II, and III. Receptor types are grouped based on receptor structure and physiological activity. www.MedChemExpress.com 1 mGluR Agonists, Antagonists, Inhibitors, Modulators & Activators (-)-Camphoric acid (1R,2S)-VU0155041 Cat.

Glycosylation: Rising Potential for Prostate Cancer Evaluation
cancers Review Glycosylation: Rising Potential for Prostate Cancer Evaluation Anna Kałuza˙ * , Justyna Szczykutowicz and Mirosława Ferens-Sieczkowska Department of Chemistry and Immunochemistry, Wroclaw Medical University, Sklodowskiej-Curie 48/50, 50-369 Wroclaw, Poland; [email protected] (J.S.); [email protected] (M.F.-S.) * Correspondence: [email protected]; Tel.: +48-71-770-30-66 Simple Summary: Aberrant protein glycosylation is a well-known hallmark of cancer and is as- sociated with differential expression of enzymes such as glycosyltransferases and glycosidases. The altered expression of the enzymes triggers cancer cells to produce glycoproteins with specific cancer-related aberrations in glycan structures. Increasing number of data indicate that glycosylation patterns of PSA and other prostate-originated proteins exert a potential to distinguish between benign prostate disease and cancer as well as among different stages of prostate cancer development and aggressiveness. This review summarizes the alterations in glycan sialylation, fucosylation, truncated O-glycans, and LacdiNAc groups outlining their potential applications in non-invasive diagnostic procedures of prostate diseases. Further research is desired to develop more general algorithms exploiting glycobiology data for the improvement of prostate diseases evaluation. Abstract: Prostate cancer is the second most commonly diagnosed cancer among men. Alterations in protein glycosylation are confirmed to be a reliable hallmark of cancer. Prostate-specific antigen is the biomarker that is used most frequently for prostate cancer detection, although its lack of sensitivity and specificity results in many unnecessary biopsies. A wide range of glycosylation alterations in Citation: Kałuza,˙ A.; Szczykutowicz, prostate cancer cells, including increased sialylation and fucosylation, can modify protein function J.; Ferens-Sieczkowska, M. -

It should be stable for at least two years. Pacritinib is supplied as a crystalline solid. A stock solution may be made by dissolving the pacritinib in the solvent of choice. Pacritinib is soluble in the organic solvent DMSO, which should be purged with an inert gas, at a concentration of approximately 0.5 mg/ml (slightly warmed). Pacritinib is sparingly soluble in aqueous solutions. To enhance aqueous solubility, dilute the organic solvent solution into aqueous buffers or isotonic saline. If performing biological experiments, ensure the residual amount of organic solvent is insignificant, since organic solvents may have physiological effects at low concentrations. We do not recommend storing the aqueous solution for more than one day. Description FMS-like tyrosine kinase 3 (FLT3) and Janus kinase 2 (JAK2) are tyrosine kinases that mediate cytokine signaling and are frequently mutated in cancers, particularly acute myeloid leukemia.1,2 Pacritinib is an 1 inhibitor of both FLT3 and JAK2 (IC50s = 22 and 23 nM, respectively). -
Identification of Candidate Repurposable Drugs to Combat COVID-19 Using a Signature-Based Approach
www.nature.com/scientificreports OPEN Identifcation of candidate repurposable drugs to combat COVID‑19 using a signature‑based approach Sinead M. O’Donovan1,10, Ali Imami1,10, Hunter Eby1, Nicholas D. Henkel1, Justin Fortune Creeden1, Sophie Asah1, Xiaolu Zhang1, Xiaojun Wu1, Rawan Alnafsah1, R. Travis Taylor2, James Reigle3,4, Alexander Thorman6, Behrouz Shamsaei4, Jarek Meller4,5,6,7,8 & Robert E. McCullumsmith1,9* The COVID‑19 pandemic caused by the novel SARS‑CoV‑2 is more contagious than other coronaviruses and has higher rates of mortality than infuenza. Identifcation of efective therapeutics is a crucial tool to treat those infected with SARS‑CoV‑2 and limit the spread of this novel disease globally. We deployed a bioinformatics workfow to identify candidate drugs for the treatment of COVID‑19. Using an “omics” repository, the Library of Integrated Network‑Based Cellular Signatures (LINCS), we simultaneously probed transcriptomic signatures of putative COVID‑19 drugs and publicly available SARS‑CoV‑2 infected cell lines to identify novel therapeutics. We identifed a shortlist of 20 candidate drugs: 8 are already under trial for the treatment of COVID‑19, the remaining 12 have antiviral properties and 6 have antiviral efcacy against coronaviruses specifcally, in vitro. All candidate drugs are either FDA approved or are under investigation. Our candidate drug fndings are discordant with (i.e., reverse) SARS‑CoV‑2 transcriptome signatures generated in vitro, and a subset are also identifed in transcriptome signatures generated from COVID‑19 patient samples, like the MEK inhibitor selumetinib. Overall, our fndings provide additional support for drugs that are already being explored as therapeutic agents for the treatment of COVID‑19 and identify promising novel targets that are worthy of further investigation. -

The Use of Ataluren in the Effective Management of Duchenne Muscular Dystrophy
Review Neuromuscular Diseases Early Diagnosis and Treatment – The Use of Ataluren in the Effective Management of Duchenne Muscular Dystrophy Eugenio Mercuri,1 Ros Quinlivan2 and Sylvie Tuffery-Giraud3 1. Catholic University, Rome, Italy; 2. Great Ormond Street Hospital and National Hospital for Neurology and Neurosurgery, London, UK; 3. Laboratory of Genetics of Rare Diseases (LGMR), University of Montpellier, Montpellier, France DOI: https://doi.org/10.17925/ENR.2018.13.1.31 he understanding of the natural history of Duchenne muscular dystrophy (DMD) is increasing rapidly and new treatments are emerging that have the potential to substantially improve the prognosis for patients with this disabling and life-shortening disease. For many, Thowever, there is a long delay between the appearance of symptoms and DMD diagnosis, which reduces the possibility of successful treatment. DMD results from mutations in the large dystrophin gene of which one-third are de novo mutations and two-thirds are inherited from a female carrier. Roughly 75% of mutations are large rearrangements and 25% are point mutations. Certain deletions and nonsense mutations can be treated whereas many other mutations cannot currently be treated. This emphasises the need for early genetic testing to identify the mutation, guide treatment and inform genetic counselling. Treatments for DMD include corticosteroids and more recently, ataluren has been approved in Europe, the first disease-modifying therapy for treating DMD caused by nonsense mutations. The use of ataluren in DMD is supported by positive results from phase IIb and phase III studies in which the treatment produced marked improvements in the 6-minute walk test, timed function tests such as the 10 m walk/run test and the 4-stair ascent/descent test compared with placebo.
