Arcapillin

Arcapillin is a flavonoid that can be isolated from Artemisia capillaris Thunb. Arcapillin induces dose-dependent relaxation of ileum and pulmonary artery smooth muscle, causes slight urinary bladder smooth muscle contraction at highest tested concentrations. Arcapillin binds to the active site of SARS-CoV-2 M_pro via interactions with Gln139, His163, and His164, exhibits antiviral activity against SARS-CoV-2 and MERS-CoV. Arcapillin can be used for the research of gastrointestinal disorders, COVID-19, and Middle East respiratory syndrome (MERS).

Biological Activity

Description

IC₅₀ & Target

PTP1B^[1]

In Vitro

Arcapillin binds to the SARS-CoV-2 main protease (PDB: 7L0D) with a docking score of -6.16 kcal mol⁻¹, indicating favorable interactions with the enzyme's active site^[2].
Arcapillin (72 h) exhibits antiviral activity against SARS-CoV-2 in Vero E6 cells with an IC₅₀ of 190.8 μg mL⁻¹, and has a low cytotoxic profile in the same cell line with a CC₅₀ of 1228 μg mL⁻¹, yielding a selectivity index of 6.40^[2].
Arcapillin (72 h) exhibits potent antiviral activity against MERS-CoV in Vero E6 cells with an IC₅₀ of 16.58 μg mL⁻¹, and has a CC₅₀ of 54.17 μg mL⁻¹ in the same cell line, yielding a selectivity index of 3.26^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
