We report that RNA modification of the cap portion by host 2'-O-ribose methyltransferase 1 (MTr1) is essential for theinitiation of influenza A and B virus replication, but not for other cap-snatching viruses. We identified with in silico compoundscreening and functional analysis a derivative of a natural product from Streptomyces, called trifluoromethyl-tubercidin (TFMT),that inhibits MTr1 through interaction at its S-adenosyl-l-methionine binding pocket to restrict influenza virus replication.Mechanistically, TFMT impairs the association of host cap RNAs with the viral polymerase basic protein 2 subunit in human lungexplants and in vivo in mice. TFMT acts synergistically with approved anti-influenza drugs.展开更多
