Abstract Background: Coronavirus disease (COVID-19) caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is now a pandemic which began in Wuhan province of China. Drug discovery teams around the globe are in a race to develop a medicine for its management. For a novel molecule to enter into the market it takes time and the ideal way is to exploit the already approved drugs and repurpose them to use therapeutically.Methods: In this work, we have attempted to screen selected molecules that have shown an affinity towards multiple protein targets of COVID-19 using Schrödinger suit. Molecules were selected from approved antiviral, anti-inflammatory or immunomodulatory classes. The viral proteins selected were angiotensin-converting enzyme 2 (ACE2), main protease (Mpro) and spike protein. Computational tools such as molecular docking, prime MM-GBSA, induced-fit docking (IFD) and molecular dynamics (MD) simulations were used to identify the most suitable molecule that forms a stable interaction with the selected viral proteins.Results: The ligand-binding stability for the viral proteins PDB-IDs 1ZV8 (spike protein), 5R82 (Mpro) and 6M1D (ACE2), was in the order of Nintedanib>Quercetin, Nintedanib>Darunavir, Nintedanib> Baricitinib respectively. The MM-GBSA, IFD, and MD simulation studies infer that the drug nintedanib has the highest binding stability among the shortlisted molecules towards the selected viral target proteins. Conclusion: Nintedanib, which is primarily used for idiopathic pulmonary fibrosis, can be considered for repurposing and used in the management of COVID-19.

Neuronal Disorders

Modulation of multiple protein targets with a single compound is essential for the effective treatment of central nervous system disorders. In our previous G protein-coupled receptor (GPCR) cell-based study, a selective human monoamine oxidase (hMAO)-A inhibitor, eckol, stimulated activity of dopamine D3 and D4 receptors. This result led to our interest in marine phlorotannin-mediated modulation of hMAO enzymes and related GPCRs in neuronal disorders. Here, we evaluate the multi-target effects of phloroglucinol, phlorofucofuroeckol-A (PFF-A), and dieckol by screening their modulatory activity against hMAO-A and -B and various neuronal GPCRs. Among the tested phlorotannins, PFF-A showed the strongest inhibitory activity against both hMAO isoforms, with higher selectivity toward hMAO-B than hMAO-A. Enzyme kinetics and docking data revealed that PFF-A noncompetitively acts on hMAOs into the alternative binding pocket of enzymes with allosteric functions. In a functional assay for GPCR screening, dieckol and PFF-A exhibited a multi-target combination of D3R/D4R agonism and D1/5HT1A/NK1 antagonism. In particular, they effectively stimulated D3R and D4R, compared to other GPCRs. Docking analysis confirmed that dieckol and PFF-A successfully docked into the conserved active sites of D3R and D4R and interacted with aspartyl and serine residues in the orthosteric binding pockets of the respective receptors. Based on our experimental and computational data, we established the structure-activity relationship between tested phlorotannins and target proteins, including hMAOs and GPCRs. Our current findings suggest that hMAO inhibitors dieckol and PFF-A, major phlorotannins of edible brown algae with multi-action on GPCRs, are potential agents for treatment of psychological disorders and Parkinson’s disease.

Initial Characterization

Cortactin was first identified over a decade ago, and its initial characterization as both an F-actin binding protein and v-Src substrate suggested that it was likely to be a key regulator of actin rearrangements in response to tyrosine kinase signalling. The recent discovery that cortactin binds and activates the actin related protein (Arp)2/3 complex, and thus regulates the formation of branched actin networks, together with the identification of multiple protein targets of the cortactin SH3 domain, have revealed diverse cellular roles for this protein. This article reviews current knowledge regarding the role of cortactin in signalling to the actin cytoskeleton in the context of these developments.
