• Isolation and In Silico Anti-SARS-CoV-2 Papain-Like Protease Potentialities of Two Rare 2-Phenoxychromone Derivatives from Artemisia spp 

      Suleimen, Yerlan M.; Suleimen, Y.M.; Jose, Eslam B.; Elkaeed, E.B.; Eissa, Ibrahim H.; Eissa, I.H.; Metwaly, Ahmed M. (Molecules, 2022)
      Two rare 2-phenoxychromone derivatives, 6-demethoxy-4‘-O-capillarsine (1) and tenuflorin C (2), were isolated from the areal parts of Artemisia commutata and A. glauca, respectively, for the first time. Being rare in nature, the inhibition potentialities of 1 and 2 against SARS-CoV-2 was investigated using multistage in silico techniques. At first, molecular similarity and ...

      A new dicoumarin, jusan coumarin, (1), has been isolated from Artemisia glauca aerial parts. The chemical structure of jusan coumarin was estimated, by 1D, 2D NMR as well as HR-Ms spectroscopic methods, to be 7-hydroxy-6-methoxy-3-[(2-oxo-2H-chromen-6-yl)oxy]-2H-chromen-2- one. As the first time to be introduced in nature, its potential against SARS-CoV-2 has been estimated using ...

    • Jusanin, a New Flavonoid from Artemisia commutata with an In Silico Inhibitory Potential against the SARS-CoV-2 Main Protease 

      Suleimen, Yerlan M.; Jose, Rani A.; Suleimen, Raigul N.; Arenz, Christoph; Ishmuratova, Margarita Y.; Toppet, Suzanne; Dehaen, Wim; Alsfouk, Bshra A.; Elkaeed, Eslam B.; Eissa, Ibrahim H.; Metwaly, Ahmed M. (Molecules, 2022-03)
      A new flavonoid, Jusanin, (1) has been isolated from the aerial parts of Artemisia commutata. The chemical structure of Jusanin has been elucidated using 1D, 2D NMR, and HR-Ms spectroscopic methods to be 5,20 ,40 -trihydroxy-6,7,50 -trimethoxyflavone. Being new in nature, the inhibition potential of 1 has been estimated against SARS-CoV-2 using different in silico techniques. ...
