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, but this mechanism belongs to an anti-viral activity while the record is filed as ANTIFUNGAL. Either the compound has both activities, or the filing is wrong — the priority table has put azole antifungals under ANTIBACTERIAL before now. A curator should decide which. 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.
