“…Bizzarri et al exploited the regioselective oxidation of coumarin derivatives with 2-iodoxybenzoic acid (IBX) and found that pyrogallol derivatives 88 (IC 50 69.9 μg/ml) and 89 (IC 50 47.9 μg/ml) were more active than catechol derivatives 84 (IC 50 106.5 μg/ml) and 85 (IC 50 91.5 μg/ml) (Bizzarri et al, 2017). Previous studies reported that isoimperatorin exhibits strong anti-influenza virus (H1N1, H9N2) activities in vitro (Lee et al, 2020), with EC 50 values (7.67 ± 0.93 μM and 6.72 ± 0.51 μM, respectively) comparable to that of ribavirin. However, the antiviral mechanism of isoimperatorin is not clear.…”

“…A recent study has shown that isoimperatorin may have antiviral effects on herpes simplex virus-1 and coxsackievirus B3 (Rajtar et al, 2017). Furthermore, it may could anti-H1N1 and H9N2 influenza virus in vitro (Lee et al, 2020). However, its antiviral mechanism of action is still unclear.…”

“…Column chromatography on silica gel (CC) has been used for the isolation of OP from the root methanolic fraction of A. dahurica [ 16 , 17 , 18 ]. This compound has been isolated from ethanolic and n -butanol (BuOH)-soluble partitions of this species by exploiting CC [ 19 ] and recrystallization [ 20 ], respectively; as well as from the CHCl 3 and CH 2 Cl 2 soluble fractions using CC [ 21 ] and recrystallization methods [ 22 ], and CC on silica gel [ 23 , 24 ], respectively.…”

“…In this study, administration of OP (20 μM, after 2 h) considerably decreased the levels of viral proteins NP (nucleoprotein) and NA (neuraminidase) in the treated cells to less than 20% via inhibition of their synthesis. The EC 50 values were measured at 5.98 ± 0.71 and 4.52 ± 0.39 μM against influenza A-H1N1 and influenza A-H9N2, respectively; while ribavirin possessed 6.29 ± 0.89 and 6.13 ± 0.19 μM, respectively [ 20 ]. Nonetheless, in accordance with Shokoohinia et al [ 61 ], no anti-HSV (antiherpes) activity was detected for OP against the Vero cell line (African monkey kidney).…”

“…Currently, commonly used anticancer drugs such as paclitaxel and vincristine are extracted from natural plants [ 5 , 6 ]. The traditional Chinese medicine Angelica dahurica has antioxidant, anti-inflammatory, and antiviral activities [ 7 9 ]. It also shows anticancer activity in a variety of tumors [ 10 12 ].…”
