Cross-references

Identifiers for this same structure in other resources. An accession that lands on two different structures in this corpus is withheld from both rather than shown here, since it names at most one of them.

Drug registries

Identifiers that name a drug rather than a structure. One of these can cover a parent compound, its salts and its stereoisomers, which this corpus keeps as separate records, so it is not an equivalence of structure.

Mechanism summary

Mode of action: ENERGY_METABOLISM_INHIBITION host shared target — Assigned from ChEBI role CHEBI:141153 (quinone outside inhibitor), CHEBI:38499 (mitochondrial cytochrome-bc1 complex 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.
