A chemical equivalent. Pyrimethamine [5-(4-chlorophenyl)-6-ethylpyrimidine-2,4-diamine Chloridine], an FDAapproved chemical molecule, is highly selective against the proteins that trigger dengue fever. Its efficacy against DENV has been previously documented [53]. Consequently, it has been advisable that various natural ligands be utilized to attack particular infectious and harmful targets. Additionally, utilizing all-natural substances to treat several different lately emerging infections has turn out to be a popular strategy in medicinal chemistry due to the fact these molecules are unlikely to induce adverse effects that would otherwise be induced by pharmaceuticals [54]. Additionally, these bioactive organic ligands are important elements of extensively offered plants with significant therapeutic possible, which are nevertheless utilized in regular medicine to treat several different viral infections [55].Molecules 2021,26, x FOR PEER REVIEW14 ofMolecules 2021, 26,NS1(4O6B)Phe178 SerAsp176 Asp180 Cys2.32 two.42 2.15 of-6.(A)(B)Molecules 2021,26, x FOR PEER REVIEW15 of(C)(D)FigureFigure 7.
