Artemisinin is a natural bioactive sesquiterpene lactone containing an unusual endoperoxide 1, 2, 4-trioxane ring. It derived from the herbal medicinal plant Artemisia annua and best known for its use in treatment of malaria. However, recent studies also indicate potential artemisinin related compounds, commonly referred to as artemisinins, combating viral infections, inflammation certain cancers. Moreover, different modes action artemisinins make these compounds potentially relevant challenges world faces COVID-19 pandemic.

Using surface-initiated atom-transfer radical polymerization, temperature-responsive block polymers were functionalized on the surface of silica nanocapsules (SNCs) by a "grafting-from" technique. Favipiravir, potential medicine candidate for treatment coronavirus disease (COVID-19), was encapsulated in polymer-coated SNCs and further incorporated into well-defined films layer-by-layer self-assembly. The multilayer composed poly(methacrylic acid) (PMAA) homopolymers exhibited swelling/deswelling behaviors under trigger temperature stimulus.

Currently there is not an effective antiviral treatment for COVID-19, but a large number of drugs have been evaluated since the beginning pandemic, and many them used COVID-19 despite preliminary or conflicting results clinical trials. We aimed to review summarize all current knowledge on antivirals COVID-19There are 2 main drug groups SARS-CoV-2: agents that target proteins RNA virus interfere with biological processes in host support virus. The include inhibitors viral entry into human cell (convalescent plasma, monoclonal antibodies, nanobodies, mini proteins, soluble ACE-2, camostat, dutasteride, proxalutamide, bromhexin, hydroxychloroquine, umifenovir nitazoxanid, niclosamide, lactoferrin), proteases (lopinavir/ritonavir, PF-07321332, PF-07304814, GC376), (remdesivir, favipiravir, molnupiravir, AT-527, merimepodib, PTC299), supporting (plitidepsin, fluvoxamine, ivermectin), natural immunity (Interferons).When taking account available laboratory trials subject, antibodies seem be most at moment, high-titer convalescent plasma also could when administered during early phase disease. As lopinavir/ritonavir, were found ineffective RCTs, they should used.

The aim this study was to evaluate safety efficacy fluvoxamine patients if administered later course disease. Methods designed open‐label, prospective cohort trial with matched controls. In April May 2021, 51 ICU hospitalised University Hospital Dubrava Centre Zagreb, Croatia, were treated 100 mg times daily for 15 days addition standard therapy they prospectively age, gender, vaccination against COVID‐19, disease severity comorbidities Results No statistically significant differences between groups observed regarding number on ventilator support, duration or total hospital stay. However, overall mortality lower group, 58.8% ( n = 30/51), than control 76.5% 39/51), HR 0.58, 95% CI (0.36–0.94, P .027). Conclusion Fluvoxamine could have positive impact patient survival. Further studies effects are urgently required.
