Retusin (Quercetin-3,3',4',7-tetramethylether) is a tyrosinase inhibitor, with IC₅₀ values of 50.9 μM and 51.8 μM against mushroom and intracellular tyrosinase, respectively. Retusin also acts as a free radical scavenger, melanogenesis inhibitor, anti-apoptosis agent, neuroprotective agent, antiemetic, antifungal agent, and antiviral agent. Retusin scavenges ABTS•⁺ and DPPH• free radicals. Retusin can be used in studies related to hyperpigmentation, vomiting, Aspergillus niger infection, and COVID-19 infection.

In Vitro

Retusin (20-80 μM; 48 h) reduces the viability of B16F10 mouse melanoma cells to 35.7% (40 μM) and 3.2% (80 μM) of that in the control group, while decreasing the viability of HaCaT human keratinocytes to 99.2% (20 μM) and 40.4% (40 μM) of the control level^[1].
Retusin (10 μM; 48 h) reduces α-MSH-induced melanin production to 56.6% of that in the control group and decreases cellular tyrosinase activity to 49.9% of the control level in B16F10 mouse melanoma cells^[1].
Retusin (0.1-10 μM; 24 h) considerably increases the percentage of live Neuro-2a cells and decreases the number of early apoptotic cells^[2].
Retusin (24-48 h) potently inhibits Aspergillus niger with an MIC of 100 μg/mL; at a concentration of 100 μg/mL, this compound shows no activity against the tested bacteria, other fungi or yeasts^[4].
Retusin (0.01-10 μM; 24 h) potently inhibits SARS-CoV-2 replication in Vero E6 cells, with an EC₅₀ of 0.4 μM^[5].
Retusin (0.01-10 μM; 48 h) potently inhibits SARS-CoV-2 replication in Calu-3 cells, with an EC₅₀ of 0.6 μM^[5].

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.
