To conquer COVID-19, create the perfect pill was written by Bethany Halford. And the article was included in Chemical & Engineering News in 2021.Recommanded Product: ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate The following contents are mentioned in the article:
As COVID-19 continues to take a global toll, drugmakers are racing to develop antiviral pills that could turn the tide of the pandemic. But the road to developing an antiviral treatment is long and hard. Often, promising candidates never make it to patients. Read on to learn about the most advanced SARS-CoV-2 antiviral candidates and what makes drugging viruses such a challenge (see page 32). As the COVID-19 crisis unfurled, scientists accomplished feats once considered impossible. Cheap, reliable COVID-19 tests are now readily available in many parts of the world. And the fact that hundreds of millions of people have taken safe and effective vaccines for a virus first identified only 18 mo ago is a marvel of modern medicine. But those advances may not be enough to end the pandemic. COVID-19 could linger for years as many remain unvaccinated and as the virus continues to mutate, potentially making variants that render vaccines less effective. Drugmakers continue to pursue the elusive goal of a pill that kills SARS-CoV-2. Gilead Sciences is hoping to tweak its antiviral drug remdesivir (marketed as Veklury) so that it can be given orally. Merck & Co. is pouring resources into molnupiravir, a compound that was in early development at the Emory Institute for Drug Development for other diseases before the COVID-19 pandemic. And Pfizer started developing its oral SARS-CoV-2 inhibitor PF-07321332 from scratch. Gilead scientists have been redecorating the core mol., known as GS-441524, in an attempt to boost its oral bioavailability. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Recommanded Product: ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate).
((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Recommanded Product: ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate
