Dear editor,Severe acute respiratory syndrome coronavirus2(SARS-CoV-2)infection can lead to severe outcomes in patients with cancer[1].It has been reported that patients with lung cancers disproportionately manifest severe COVID-19 with a high rate of hospitalization and death[2].Notably,the SARS-CoV-2 Spike(S)protein can induce hyper-inflammation in both epithelial cells and macrophages through toll-like receptor(TLR)1/TLR2 or TLR2/6-dependent nuclear factor-kappaB(NF-κB)path-way[3].However,molecular and cellular evidence on whether the SARS-CoV-2 virus affects the severity of lung cancer patients through TLR1/2 or TLR2/6 signaling remains unclear.

Goji berry is a famous edible and medicinal substance around the world. In this research， 15 phenylpropionyl phenylethylamine derivatives (1-15)， including one new compound (1)， were separated and identified from goji berry. All isolates were elucidated via extensive NMR spectral analyses and chemical techniques. Six known isolates were first obtained from Lycium genus. Six isolates were effectively split into double chromatographic peaks accompanied by the basically identical areas， indicating they belong to racemates. The ORAC experiment indicated that all isolates displayed a capacity of scavenging free radicals， and most of them exhibited higher ORAC values than EGCG. In ethanol/palmitic acid (PA)-established in vitro hepatocyte injury model， four phenylpropionyl phenylethylamine derivatives (1， 2， 9， and 15) significantly alleviated hepatocyte injury， among which compound 1 exerted the strongest protective activity. Notably， the hepatoprotective effect of compound 1 was further confirmed in ethanol-established liver damage mouse model， reflected by the reduction of lipid accumulation and the attenuation of pathological alteration. Combined with the in vitro results， the in vivo observations suggested that compound 1 suppressed cell apoptosis and the outburst of inflammation. Our findings provided first-hand evidence proving that goji berry-derived phenylpropionyl phenylethylamine derivatives hold a potential in treating alcoholic liver disease.
