Mice K18-hACE2 mice intraperitoneal injection 15 mg/kg/day once daily for 3 days MRT67307 significantly reduced lung inflammation and immune cell infiltration in SARS-CoV-2-infected mice, indicating its therapeutic potential for COVID-19-related inflammation. PMC10507085
Mouse IKK ε knockout mice In vitro culture 10 µM 30 minutes MRT67307 significantly decreased CYLD phosphorylation in wild-type cells, but there was no difference in CYLD phosphorylation between wild-type and IKK ε knockout cells. Moreover, CYLD phosphorylation was still inhibited by MRT67307 in IKK ε deficient cells, suggesting that TCR-induced CYLD phosphorylation is independent of IKK ε. PMC5932415
