Pimodivir is a substrate for CYP3A4 metabolism but itself has no inhibitory or induction effects on the isoenzyme. PB2-E627K is the best characterized human-adaptation mutation in AI viruses, particularly H5N1 viruses [31, 32], and is readily acquired by H9N2 viruses during passage in mice [33, 34]. The replication of the PB2 627K mutant virus was also unchanged in this context. Research output: Contribution to journal › Article › peer-review. It is also a substrate for P-glycoprotein and OATP1B1 and also inhibits P-glycoprotein. These findings imply that huANP32A has less of a role in maintaining the high polymerase activity of H7N9 PB2 627K virus.
