Ebselen a rheumatoid prescription drug kills COVID,HIV and antibiotic resistant bacteria like MRSA
I think its a test on our gullibility...
Before we started the "15 days to flatten the curve" I replenished my supply of zinc caplets and ordered some quercetin. I haven't opened the package of quercetin. I might take a zinc caplet before heading out shopping if I think of it. Pretty sure I haven't thought of it for the past few months though.
When this thing was all starting out, we all saw the videos of people in China, walking down the street and then dropping over, apparently dead. For some reason, that seems to be what a lot of people still think we're dealing with. Even the people who downplay the Covid hysteria still act like it's something to be genuinely afraid of.
As for me, I don't fear Covid in the least.
And someone who posts word salads on FR to boot.
Sure, we’re supposed to rush right out and buy a prescription medication just how?
Tell our dr that some anonymous, self-proclaimed, self-styled “prophet” told us to take it so he needs to write us a script post haste.
Yeah….. that’ll work really well.
Got any proof besides your say so?
You state your opinion with no back up or proof and then just disappear.
Why are we supposed to take your word for it?
Well my friend, you can’t go wrong with Ivermectin, NAC as well as Quercetin. Just remember to take NAC always with at least two to three times as much ascorbic acid, better known as C, otherwise it may not do you much good. Aside from that it is a good idea to keep NAC, C, as well as quercetin along with zinc in your blood stream on a daily basis and don’t wait for any of these crappy viruses to hit you first. It still will help but not as well as if you are already fortified. Well just a thought....Stay well!
MIA.
Brief Summary:
This study evaluates the effect of a ‘lithium like’ drug called ebselen (SP-1005) versus placebo as an ‘add on’ treatment to help stabilise hypo/manic symptoms in bipolar disorder.
Half of the participants will receive ebselen and the other half placebo. The trial, will last a total of four weeks.

Tell us more.
Just about everything kills it except for the vaccines.
ebselen is an investigational drug, not proven or approved for anything, and not available anywhere for purchase ... your post is bullshit ...
I always take medical advice with no source from random people on the internet.
Got any more bright ideas?
Ebselen, a new candidate therapeutic against SARS-CoV-2

Additional article information
We read with great interest the recently published article by Abbasi-Oshaghi et al. that discussed the potential of repurposing FDA-approved drugs and other therapeutic strategies for managing COVID-19-associated deaths [1]. We would like to compliment, and add our analysis on another strategy that targets glutathione peroxidase 1 (GPX1) detoxifying system and the main protease (Mpro) of SARS-CoV-2 for treating COVID-19 patients. This is made possible by utilizing the GPX1-mimetic drug, ebselen.
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China was accompanied by the need for developing specific therapeutics that can put an end to the ongoing pandemic. However, the development of a novel SARS-CoV-2-specific drug will take several years and cost billions because of the need to establish efficacy and long-term safety profiles. Therefore, the repurposing of already known drugs with well-established safety profiles can accelerate the evaluation process and shorten the gap between efficacy studies and their clinical utility. Recently, Jin et al. have assayed more than 10,000 compounds using a combination of structure-based virtual and high-throughput screening to identify efficient inhibitors of main protease (Mpro), a key enzyme of SARS-CoV-2. One of the six compounds that inhibited SARS-CoV-2 Mpro, ebselen (SPI-1005), also exhibited promising antiviral activity in cell-based assays [2]. Ebselen (2-phenyl-1,2-benzoisoselenazol-3(2H)-one) is an organoselenium compound with hydroperoxide- and peroxynitrite-reducing activity (Figure - 1 ). Biologically it acts as an enzyme mimetic, catalyzing the glutathione peroxidase reaction [3]. Ebselen has also been reported to possess antioxidant, anti-inflammatory, and cytoprotective properties [2].

Ebselen has been previously found to exhibit potent antiviral activity against many viruses including human immunodeficiency virus type 1 (HIV-1) [4], hepatitis C virus (HCV) [5], influenza A virus [6], and Zika virus [7]. The antiviral activity of ebselen against HIV-1 is mediated via the inhibition of HIV-1 capsid protein, which has a central role in the events leading to viral infection [8]. Furthermore, the in vitro studies have validated that the antiviral activity of ebselen can also be attributed to its ability to interferes with the binding of chromatin-associated host cell molecule and lens-epithelium-derived growth-factor (LEDGF/p75) to HIV-1 integrase resulting in failure of viral genome integration to the host cell DNA [4]. However, the antiviral action of ebselen against the hepatitis C virus (HCV) is mediated via the inhibition of NS3 helicase activity that is required for viral assembly and replication but does not inhibit the protease activity [5].
Apart from promising antiviral activity, ebselen also possess antioxidant, anti-inflammatory, antimalarial, anti-trypanosomal and cytoprotective properties indicating a broad spectrum of activity [2,9,10]. Interestingly, ebselen is also considered for the prevention of noise-induced hearing loss and bipolar disorder, currently being studied in a phase-2 trial [11,12]. Early research on ebselen documented that it has numerous targets in biological pathways with a distinct mechanism of action and can be utilized for treating different clinical conditions, attributing to its broad spectrum of activity [13].
As an antiviral drug against SARS-CoV-2, ebselen acts through the inhibition of the main viral protease, Mpro [14]. The main protease is one of the crucial enzymes in the viral life cycle that plays a key role in viral replication and transcription process [15]. Inhibition of Mpro and subsequently, the nonstructural proteins (Nsps) arrests the process of viral assembly in the SARS-CoV-2 replication cycle, making it a promising drug for treating COVID-19 patients (Figure - 2 ). Studies using experimental animal models have demonstrated that ebselen, when given orally, effectively combats lung inflammation, possibly by inhibition of leukocyte infiltration, IL1β, TNFα, and inflammatory cytokines in the lungs [16]. Pre-treatment of mice with ebselen at the dose of 10 mg/kg given orally before intranasal inoculation and infection with influenza A virus (H3N2) have resulted in the significant reduction of virus titers, leukocyte count in bronchioalveolar lavage fluid, and expression of inflammatory cytokines [17]. Therefore, the anti-inflammatory activity exhibited by ebselen in the lungs can be utilized to treat COVID-19, as the primary target organ of SARS-CoV-2 is lungs. Further studies are required to evaluate the beneficial interaction of ebselen with the replication cycle of SARS-CoV-2.

Besides its direct antiviral activity against SARS-CoV-2, ebselen also possess excellent anti-inflammatory property owing to the thiol-mediated and peroxiredoxin-like inhibitory effects on inflammation. Ebselen is likely to exhibit potential effects in inflammatory conditions sequential to acute respiratory distress syndrome (ARDS), one of the primary reasons for mortality in COVID-19 patients [3]. Moreover, it is also reported that ebselen can correct the disturbances in iron homeostasis induced by stressful stimuli in rats [18]. The increased release of iron from the circulating ferritin in COVID-19 patients disturbs the iron homeostasis, thereby increasing the susceptibility to cytotoxicity and increased chances of mortality. Therefore, treatment with ebselen can further decrease the mortality rate in SARS-CoV-2 infection [19].
In the SARS-CoV-2 context, the proposed antiviral activity of ebselen identified based on crystallographic studies is mediated via the direct inhibition of the main protease through non-covalent binding with cysteine present in the active site of Mpro forming selenosulfide [2]. It has been also demonstrated that the ebselen at half-maximal effective concentration (EC50) value of 4.67 μM has exhibited inhibitory activity against SARS-CoV-2 in cell-based assays. Furthermore, the dose-response curve suggests it can penetrate the cell membranes and access their targets [2]. Even though the antiviral activity of ebselen is well documented based on in silico and in vitro studies, further investigation is warranted using in vivo studies with suitable animal models. Additional studies are also required to investigate whether ebselen affects capsid formation and viral replication in SARS-CoV-2, as in the case of HIV-1 or HCV [3].
It has also been proven that ebselen is capable of inhibiting liver injury induced by chemical and microbial stimuli [20]. One of the most common findings observed in severe cases of COVID-19 is liver injury [21]. Therefore, treatment with ebselen might also have added benefits in this particular aspect of the disease. Moreover, ebselen is also found to be effective in managing focal ischemic injury by decreasing IL-6 [22], which can protect SARS-CoV-2 infected patients with venous thrombosis and vascular injury [23]. Nevertheless, the findings of these previous studies give us hope for the therapeutic potential of ebselen in managing COVID-19. Further investigations are required using randomized clinical control trials before they can be included in any treatment regimen. Considering the therapeutic potential of ebselen in COVID-19, two major clinical trials have already been registered to evaluate the safety and efficacy of this repurposed drug in moderate and severe COVID-19 patients (Table 1 ).

Clinical trials evaluating the therapeutic efficacy and safety of ebselen (SPI-1005) in COVID-19 patients (www.clinicaltrials.gov).
Although ebselen exhibits potential antiviral activity against SARS-CoV-2, its effectiveness can be impeded by certain unknown factors and therefore require further studies. For successful therapeutic use, ebselen must attain therapeutic plasma concentration sufficient to exert antiviral action. The inhibition of Mpro can be efficiently increased via the combination of ebselen with N-acetyl cysteine, a drug with cytoprotective effects that can act against SARS-CoV-2 by inhibiting virus replication, attributing to its synergistic action against the virus [24,25]. Since ebselen already possess antiviral activity against several viruses and exhibits potent antiviral activity against SARS-CoV-2 via Mpro inhibition [2], assuming the same is realized in the in vivo and clinical studies, repurposing it for SARS-CoV-2 treatment seems to be a reasonable option [3]. Therefore, ebselen can be considered as a potential therapeutic candidate for COVID-19 patients. However, before including it in the treatment guidelines and widespread use as a potential antiviral drug, further studies should be undertaken to establish its efficacy using in vitro, in vivo, and clinical studies.
Repeat of last night?
The problem is finding Ivermectin. The only place I have a link to, their website, is not user friendly.
Coincidentally, they seem to be able to control OTC/non-prescription drugs to a great extent as well.
Pppffftttt...
Ebeselen is for sale now but Fisetin is cheaper and easier to get !
Anything but horsey paste.
Thank you for bringing sanity to an otherwise senseless thread.
Buy Ebselen here !
