You are so off the wall about homebrews post, before you even looked at the link. I was even mistaken because without looking I thought it was the link to that Israeli doctor and his posted results, which are now being questioned across the world. Homebrew's link was the nobel prize for compound that fights malaria. Legit nobel prize. Homebrew was clearly stating Ivermectin itself was getting a bad rap and made no implication of it as treating covid-19.

I think you and a few more people owe homebrew an apology. You can ignore me all you want, I don't care, but you're sorely off base with your rants and attacks.

From bacteria and plants to novel anti-parasite therapies

After decades of limited progress in developing durable therapies for parasitic diseases, the discoveries by this year’s Laureates radically changed the situation.

Satoshi Omura, a Japanese microbiologist and expert in isolating natural products, focused on a group of bacteria, Streptomyces, which lives in the soil and was known to produce a plethora of agents with antibacterial activities (including Streptomycin discovered by Selman Waksman, Nobel Prize 1952). Equipped with extraordinary skills in developing unique methods for large-scale culturing and characterization of these bacteria, Omura isolated new strains of Streptomyces from soil samples and successfully cultured them in the laboratory. From many thousand different cultures, he selected about 50 of the most promising, with the intent that they would be further analyzed for their activity against harmful microorganisms (Figure 2).

Figure 2: Satoshi Omura searched for novel strains of Streptomyces bacteria as a source for new bioactive compounds. He isolated microbes from soil samples in Japan, cultured them in the laboratory (inset to left) and characterized many thousands of Streptomyces cultures. From those, he selected around 50 cultures that appeared most promising, and one of these cultures later turned out to be Streptomyces avermitilis (inset to right), the source of Avermectin.

William C. Campbell, an expert in parasite biology working in the USA, acquired Omura’s Streptomyces cultures and explored their efficacy. Campbell showed that a component from one of the cultures was remarkably efficient against parasites in domestic and farm animals. The bioactive agent was purified and named Avermectin, which was subsequently chemically modified to a more effective compound called Ivermectin. Ivermectin was later tested in humans with parasitic infections and effectively killed parasite larvae (microfilaria) (Figure 3). Collectively, Omura and Campbell’s contributions led to the discovery of a new class of drugs with extraordinary efficacy against parasitic diseases.

Figure 3: William C. Campbell discovered that one of Omura’s Streptomyces cultures was very effective in killing off parasites and the active compound, Avermectin, was purified. Avermectin was further modified to Ivermectin, which turned out to be highly effective in both animals and humans against a variety of parasites, including those that cause River Blindness and Lymphatic Filariasis.

Malaria was traditionally treated by chloroquine or quinine, but with declining success. By the late 1960s, efforts to eradicate Malaria had failed and the disease was on the rise. At that time, Tu Youyou in China turned to traditional herbal medicine to tackle the challenge of developing novel Malaria therapies. From a large-scale screen of herbal remedies in Malaria-infected animals, an extract from the plant Artemisia annua emerged as an interesting candidate. However, the results were inconsistent, so Tu revisited the ancient literature and discovered clues that guided her in her quest to successfully extract the active component from Artemisia annua. Tu was the first to show that this component, later called Artemisinin, was highly effective against the Malaria parasite, both in infected animals and in humans (Figure 4). Artemisinin represents a new class of antimalarial agents that rapidly kill the Malaria parasites at an early stage of their development, which explains its unprecedented potency in the treatment of severe Malaria.
