CHEBI:166872 ·resolve ·ANTIBACTERIAL ·EXACT SEEDED

A nucleoside antibiotic that is 5'-O-sulfamoyladenosine in which the hydrogen atom at position 4' is replaced by a fluorine atom. It is a natural product synthesized by several Streptomyces species. It exhibits broad spectrum antibacterial activity, and also has a strong effect against Trypanosoma brucei, the protozoan parasite responsible for the African sleeping sickness. — ChEBI

Mechanism summary

Mode of action: PROTEIN_SYNTHESIS_INHIBITION host shared target — Assigned from ChEBI role CHEBI:48001 (protein synthesis 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.
