ABSTRACT
Aim To explore the active compound of Maxingganshi decoction in treatment of novel coronavirus pneumonia(COVID-19). Methods With the help of TCMSP database, the chemical components and action targets of ephedra, almond, licorice, and gypsum in Maxingganshi decoction were searched, and then a C-T network, protein interaction analysis, GO functional enrichment analysis, and KEGG pathway enrichment were constructed. Analysis was performed to predict its mechanism of action. Results A total of 120 compounds in Maxingganshi decoction corresponded to 222 targets. PTGS2, ESR1, PPARG, AR, NOS2, NCOA2 acted on PI3K-Akt signaling pathway, TNF signaling pathway, IL-17 signaling pathway, T cell receptor signaling pathways, etc. The results of molecular docking showed that the affinity of quercetin, kaempferol, glabridin and other core compounds was similar to recommended drugs in treatment of COVID-19. Conclusions The active compounds of Maxingganshi decoction can target multiple pathways to achieve the therapeutic effect of COVID-19.Copyright © 2020 Publication Centre of Anhui Medical University.

ABSTRACT
A key part of many chronic diseases is inflammation controlled by inflammatory mediators. Regulation of their function allows muting the inflammatory response, which is the desired effect in the treatment of inflammatory diseases. The source of mediators is arachidonic acid, converted to pro-inflammatory mediators by cyclooxygenases (COX) or lipooxygenases (LOX). The 5-LOX pathway is full of target points for the regulation of biosynthesis of cysteinyl leukotrienes (CysLT) - one of the major classes of inflammatory mediators. These compounds exert their activity through specific leukotriene receptors - first (CysLT1R) and second (CysLT2R). Drugs that inhibit CysLT synthesis, as well as leukotriene receptor antagonists (LTRA), form a group of drugs known as anti-leukotriene drugs. Currently, only a few representatives of this group are available in the pharmacies around the world: The 5-LOX inhibitor - zileuton - and three CysLT1R antagonists - montelukast, pranlukast, and zafirlukast. LTRAs due to their wide range of anti-inflammatory effects are a group of drugs with a high potential in the treatment of inflammatory diseases. The study of new applications of known LTRAs and the search for new members of the LTRA group are the main directions of development in this field of pharmacy. This work summarizes the benefits of using anti-leukotriene drugs in the treatment of chronic diseases and presents new directions for using LTRAs.
ABSTRACT
Screening advanced compounds enables discovery of direct repurposing candidates, novel drug-like leads for optimization, and informative pharmacological probes. In this chapter, we describe different types of screening collections used in drug repurposing, discuss issues and considerations in preparing and executing a repurposing screen, and present examples of in vitro and in vivo repurposing assays. We further describe various data sources reporting information on de-risked compounds of different types and illustrate how data mining and chemoinformatic and chemogenomic searches can be used to access large numbers of advanced compounds and assemble collections most suitable for screening in a given disease model. We argue that a view of repurposing screening as a large-scale bet on finding candidates for clinical testing is narrow and incomplete. Rather, when thoughtfully executed, screening of re-risked compounds is informed by target pathobiology and offers a means to efficiently convert advances in the development of sophisticated non-clinical models and new insights in disease mechanisms into novel drug-like leads and candidates for development.
ABSTRACT
Headache is one of the most prevalent disorders of the nervous system. Headache is also the most common symptom of a variety of diseases, including migraine, COVID-19. International Classification of Headache Disorders (ICHD) lists over a thousand different types of headaches. Migraine is a widely known type of primary headache. Much research supports that the enhancement in migraine intensity related to chronic migraine such as neurogenic neuroinflammation, possibly leading to increased cytokine expression via activation of protein kinases in neurons and glial cells of the trigeminovascular system like some of the other headache diseases. No currently drug class available, either specific (triptans, ergots) or non-specific (opioids, paracetamol, NSAIDs), is effective in all types of headaches, in all patients and all attacks of the same patient. However, non-steroidal anti-inflammatory drugs (NSAIDs) minimize prostaglandin synthesis by blocking cyclooxygenase, which is included in the pathophysiology of migraine headaches. We searched the employed source was The Journal of Headache and Pain database by using NSAIDs with Headache, Migraine, and COVID-19 keywords. The search was performed from April 2021 and included 2017-2018-2019-2020-2021 (last five years) the studies and reviews from the Journal of Headache and Face Pain Sites. Additionally, we noted the published or on-going studies, eight of these, about NSAIDs information contain searches that exist in the 12th European Headache Federation Congress (jointly with 32nd National Congress of the Italian Society) Study of Headaches’ book. Also, we included relationship migraine with COVID-19 studies to highlight the connection between the headache, which is one of the most common symptoms of both migraine and COVID-19, and the importance of managing migraine pain with NSAIDs during corona processing.
