This blocks TMPRSS2 which is the exact protein ivermectin blocks.

Some quick googling doesn’t back this up and my understanding is that ivermectin has only shown itself to be effective at doses that are higher then are remotely safe. It also just isn’t the sort of thing there would be incentive to lie about. Probably then the straightforward story is true no it’s only effective as prescribed as treatment for parasites. If you’d like to provide some sources though or more explanation that would be great. Note that TMPRSS2 has been a potential target for treating covid basically since the beginning, so some one lying and claiming it as a mechanism of action isn’t surprising

  Well you're wrong. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7996102/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7996102/ "Ivermectin was found as a blocker of viral replicase, protease and human TMPRSS2."

    Computer docking simulations don't prove anything and are only possibly useful for initial drug screening.

      He said ivermectin was not found to block TMPRSS2. I linked a nih study that said it did. Now its about proving its efficacy against sars-cov-2? I believe this is called "moving the goalposts". And there we have it - in silico is fine for this new substance that will likely have a huge price tag. Not fine for an existing generic. Far fewer people are buying this nonsense these days.

        For what it's worth, that is not an NIH study; it may be listed on PubMed but it appears to be conducted by researchers at the Integrative Biochemistry & Immunology Laboratory, Department of Animal Science, Kazi Nazrul University. PubMed indexes most biomedical literature, not just research conducted by the NIH. And again, computer simulations suggesting that ivermectin may interact with a specific protein is not the same as saying that it indeed does do so in human tissue.

        Im unsure of what you are trying to say. Are you trying to say ivermectin has no impact on TMPRSS2? Ok here is another the google machine gave me. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7372205/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7372205/ What is most telling about all of this is that there is no honest discussion. My only initial comment was that this blocks the same protein that ivermectin does. Multiple studies confirm this, its easy to search for them, and it has been the hypothesized mechanism by which ivermectin may show some efficacy. Does ivermectin block TMPRSS2 or not?
        unanswered 5y ago
        No, no. You have to give a source! Like CNN, or MotherJones! Until then there's no way to know the truth about whether ivermectin blocks this protein or not. I mean there isn't even really a right answer to that question, until we hear it from reliable sources!

        Because you're waving around a study that did not test Ivermectin.

  As far as I can tell ivermectin has only been "studied" against TMPRSS2 in silico. The better-studied purported mechanism of ivermectin against SARS-CoV-2 involves something called importin [1]. On the other hand, bromhexine, which is a cough medicine used OTC around the world does inhibit TMPRSS2 and may have action against SARS-Cov-2 [2]. Bromhexine is a prodrug for ambroxol, which is also an OTC cold medicine in much of the world.

    Already in 2020 (I forget just how early), __ice9 on twitter was pointing out bromhexine and stressing the importance of blocking both ACE2 and TMPRSS2 binding ("dual-entry inhibition"). This is not an area I personally know about, but it's worth bringing up for the enthusiasts for censorship. https://twitter.com/__ice9/status/1368634545717788677 https://twitter.com/__ice9/status/1368634545717788677 If it works, the OTC nature is important. Hard for any drug to be very effective if the get-an-appointment-see-a-doctor-get-a-prescription-get-it-filled system takes you well past peak viral load before you even start using it.

  From the featured article “Janetka co-founded a biotechnology startup company called ProteXase Therapeutics” I guess you could see what their business plan is?
  - space_fountain 5y ago
    But that doesn't incentive say a PHD candidate at Harvard to agree right? They're not making any money from this new startup and they'd probably get a lot of positive news coverage if they could show a cheap cure to covid. Certainly now things are a bit locked in place so it would be harder, there would be some repetitional damage at stake, but I'm just very unconvinced a cabal of biotech startups really has the power to keep a lid on something like this

  I have no opinion whatsoever regarding whether or not ivermectin's purported mechanism of action against COVID is valid. However, this: > It also just isn’t the sort of thing there would be incentive to lie about is not true. There are two incentives to lie about this, if you are in any way associated with drug or vaccine manufacturers. 1.) Ivermectin is out of patent and dirt cheap; basically not profitable at all 2.) Emergency use authorization for the vaccines relied on there being no available alternative treatment Again, I have no opinion regarding whether or not ivermectin is remotely useful for COVID. But there are plenty of incentives aimed against any older generic being repurposed.
  - space_fountain 5y ago
    You're discussing incentives that maybe some major drug companies might have, but they aren't the only ones around. I guess, the more accurate position is that there are strong upper bounds to how effective a secretly suppressed drug could be. Imagine that ivermectin just cured covid for a minute. The would be incredibly easy to prove in a study. I mean just observational studies would be glaringly obvious. What ambitious young scientist wouldn't want curing covid on their resume? So you have to believe, either the vast majority of scientists, the press, or government are complicit in this conspiracy and I don't see strong incentives for any of those groups.
    - ralusek 5y ago
      Well that's the thing, is that there are literally millions of people in entire countries being prescribed it. India has dished out millions of doses for COVID, and there are many doctors and researchers completely convinced by clinical evidence. It's not as if there are no people picking up a signal, or that no studies are showing utility, it's that the available studies are methodologically questionable. But as you are aware, there are more formal studies taking place at the moment, and the official scientific consensus is that we don't yet know. Again, my argument against you was that you said that there was no motivation against it, and I said that wasn't true.
  - weaksauce 5y ago
    > 2.) Emergency use authorization for the vaccines relied on there being no available alternative treatment That's simply so factually wrong it's tough to take it as serious. having a treatment that might lessen the severity of some percentage of the people that get covid has absolutely nothing to do with a prophylactic EUA for a vaccine that is wildly efficacious against mild and severe covid cases and stop you from getting it in the first place. Let's do a thought experiment even if that were true... that would mean the other vaccines that are under an EUA would have been revoked the moment Pfizer got their full approval which didn't happen. This is "there are naval insignias on the flags therefore we are not a constitutional democracy" level of conspiratorial thinking. > 1.) Ivermectin is out of patent and dirt cheap; basically not profitable at all that's the reason they threw it at the virus in the first place. They were looking for anything that might help.
randomopining 5y ago
Ivermectin doesn't have any legit studies with large samples to show that it's even that useful against covid. Also, what happened to hydroxychloroquine? That was the big thing in 2020. guess 2021 is ivermectin.
- nekt 5y ago
  I am not making any claims of any of these substances effectiveness in treating covid. I'm just pointing out that this substance claims to block the same human protein ivermectin does. We can all make of that what we will.
  - ashtonkem 5y ago
    In political discussions we call this the “anti-anti” position. If you’re not making any claims that Ivermectin works, why are you wasting so much energy and karma attacking those that think it doesn’t work?
- LMYahooTFY 5y ago
  Based on what metric? The vaccines were authorized under emergency use with trial participants comparable to samples conducted with Ivermectin. How is it not worth considering for a drug that's already known to be safe to administer and cheap? Beyond that, there are practicing doctors advocating that they've had good results. This should be more than enough to consider it's use, and not dismiss it as some 'thing of the year to dismiss'.

    "The Phase 3 clinical trial of BNT162b2 began on July 27 and has enrolled 43,661 participants to date, 41,135 of whom have received a second dose of the vaccine candidate as of November 13, 2020." Wow so there was an ivermectin study with 44k people? Where is it? I agree that it should be able to be studied and probably used. But what's going on is that people are looking for an ALTERNATIVE to the vaccine... which is detrimental when the vaccine is proven to be our best tactic against death/serious illness.
