32434058 We have explicitly highlighted several useful information and facts like: i) No established relationship between progression of SARS-CoV-2 with temperature, humidity and/or both, ii) The underlying mechanism of SARS-CoV-2 is not fully understood, iii) Respiratory droplet size determines drop and airborne-based transmission, iv) Prognosis of COVID-19 can be done by its effects on various body organs, v) Infection can be stopped by restricting the binding of S protein and AE2, vi) Hydroxychloroquine is believed to be better than chloroquine for COVID-19, vii) Ivermectin with Vero-hSLAM cells is able to reduce infection by ~5000 time within 2 days, and viii) Nafamostat mesylate can inhibit SARS-CoV-2 S protein-initiated membrane fusion.
32448818 To examine the effects of protease inhibitors on the replication of coronavirus 229E, we pretreated primary cultures of human nasal epithelial (HNE) cells with camostat or nafamostat, each of which has been used for the treatment of pancreatitis and/or disseminated intravascular coagulation. […] Pretreatment with camostat (0.1-10 μg/mL) or nafamostat (0.01-1 μg/mL) reduced the titers of coronavirus 229E.
32473310 A few clinically approved drugs, such as remdesivir, chloroquine, hydroxychloroquine, nafamostat, camostat, and ivermectin, exhibited anti-SARS-CoV-2 activity in vitro and/or in a small number of patients.
32470602 Nafamostat, known as anticoagulant, has potential anti-inflammatory and anti-viral activities against COVID-19. […] We report three cases of COVID-19 pneumonia who progressed while using antiviral drugs and needed supplementary oxygen therapy, improved after treatment with nafamostat. […] These preliminary findings show the possibility that Nafamostat can be considered to be used in elderly patients with COVID-19 pneumonia who need oxygen therapy. […] The effectiveness of nafamostat should be evaluated in further studies.
32532094 We previously found that nafamostat mesylate, an existing drug used for disseminated intravascular coagulation (DIC), effectively blocked Middle East respiratory syndrome coronavirus (MERS-CoV) S protein-mediated cell fusion by targeting transmembrane serine protease 2 (TMPRSS2), and inhibited MERS-CoV infection of human lung epithelium-derived Calu-3 cells. […] Here we established a quantitative fusion assay dependent on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) S protein, angiotensin I converting enzyme 2 (ACE2) and TMPRSS2, and found that nafamostat mesylate potently inhibited the fusion while camostat mesylate was about 10-fold less active. […] Furthermore, nafamostat mesylate blocked SARS-CoV-2 infection of Calu-3 cells with an effective concentration (EC)50 around 10 nM, which is below its average blood concentration after intravenous administration through continuous infusion. […] Together, our study shows that nafamostat mesylate potently inhibits SARS-CoV-2 S protein-mediated fusion in a cell fusion assay system and also inhibits SARS-CoV-2 infection in vitro in a cell-type-dependent manner. […] These findings, together with accumulated clinical data regarding nafamostat’s safety, make it a likely candidate drug to treat COVID-19.
32550069 New anticoagulant, nafamostat, used in Japan is also discussed as a possible potentiate for heparin therapy.
32550095 We report a case of a 65-year-old man with diabetes and severe COVID-19 pneumonia requiring mechanical ventilation and treated with hydroxychloroquine, azithromycin, nafamostat, and prone positioning.
32574109 Specifically, we review the potential clinical utility of two transmembrane serine protease 2 (TMPRSS2)-targeting protease inhibitors, nafamostat mesylate and camostat mesylate, as well as two novel potent fusion inhibitors and the repurposed Ebola drug, remdesivir, which is specific to RdRp, against human coronaviruses, including SARS-CoV-2.
32586214 A number of antithrombotic drugs have been proposed as potential therapies to prevent COVID-19-associated thrombosis, including, heparin, FXII inhibitors, fibrinolytic drugs, nafamostat and dipyridamole, many of which also possess pleiotropic anti-inflammatory or anti-viral effects.
32696234 They include recombinant soluble ACE2, indirect ACE2 modulators (angiotensin receptor blockers, calmodulin antagonists, selective oestrogen receptor modifiers), TMPRSS2 inhibitors (camostat mesylate, nafamostat mesylate, antiandrogens, inhaled corticosteroids) and ADAM-17 enhancers (5-fluorouracil).
32767684 The comparative analysis of antiviral activities revealed that nafamostat is the most potent drug in human lung cells (IC50 = 0.0022 µM).
32824674 Clinical studies on TMPRSS2 inhibitors, such as camostat, nafamostat, and bromhexine, are ongoing.
32827400 Repurposing of drugs from different pharmacological groups including antivirals like remdesivir, lopinavir, ritonavir, arbidol, oseltamivir, penciclovir, favipiravir, ganciclovir, and ribavirin; other antibiotics like azithromycin, ivermectin, eravacycline, valrubicin, streptomycin, nitazoxanide, teicoplanin, caspofungin, and colistin; and other agents like hydroxychloroquine, chloroquine, tocilizumab, camostat, nafamostat, carfilzomib, interferon, aprepitant, and dexamethasone can be considered for COVID-19 therapy.
32893123 Several clinical studies have demonstrated the efficacy of chloroquine phosphate and nafamostat mesylate with COVID-19. […] Here, we report the case of a Japanese patient with COVID-19 with severe respiratory failure who improved following the administration of hydroxychloroquine and continuous hemodiafiltlation with nafamostat mesylate. […] Hence, hydroxychloroquine with nafamostat mesylate might be a treatment option for severe COVID-19.
32920751 There is limited knowledge regarding the dynamic changes in coagulation factors among COVID-19 patients on nafamostat mesylate, a potential therapeutic anticoagulant for COVID-19. […] First, we retrospectively conducted a cluster analysis based on clinical characteristics on admission to identify latent subgroups among fifteen patients with COVID-19 on nafamostat mesylate at the University of Tokyo Hospital, Japan, between April 6 and May 31, 2020. […] Although the potential of nafamostat mesylate needs to be evaluated in randomized clinical trials, admission characteristics of patients with COVID-19 could predict subsequent coagulopathy.
32972339 Both available evidence as well as hypotheses are discussed, with emphasis on drugs which are approved for other indications such as bromhexine, ammonium chloride, nafamostat, camostat, tranexamic acid, epsilon amino-caproic acid, chloroquine, ulinastatin, aprotinin and anticoagulant drugs.
32993622 Other drugs that are more likely to present clinical effects despite the lack of specific evidence for COVID-19 include anti-androgens (spironolactone, eplerenone, finasteride and dutasteride), statins, N-acetyl cysteine (NAC), ACE inhibitors (ACEi), angiotensin receptor blockers (ARB), and direct TMPRSS-2 inhibitors (nafamostat and camostat).
33042560 This report describes a COVID-19 patient treated with nafamostat and heparin to prevent circuit thrombosis during ECMO support. […] He was subsequently administered combination therapy with nafamostat and heparin. […] Combination therapy with nafamostat and heparin can prevent circuit thrombosis during ECMO.
