fluvirucin A1

CHEBI:71508 ·resolve ·ANTIVIRAL ·EXACT SEEDED

A lactam that is 4-hydroxyazacyclotetradecan-2-one substituted by an ethyl group at position 11, methyl groups at position 3 and 7 and a 3-amino-3,6-dideoxy-α-L-talopyranosyl moiety at position 4 via a glycosyl linkage (the 3R,4S,7R,11S stereoisomer). It is isolated from the fermentation broth of an unidentified actinomycete species and exhibits potent inhibitory activity against influenza A virus. — ChEBI

Mechanism summary

Mode of action: VIRAL_RELEASE_INHIBITION host shared target — Assigned from ChEBI role CHEBI:52425 (EC 3.2.1.18 (exo-α-sialidase) inhibitor). ChEBI asserts the role on the compound. The target it names is one the host has too, so the mechanism is true but is not evidence of selectivity — see mode_of_action_target_scope. Not a curator's mechanistic review.
