| Member | Definition | Role |
|---|
| 2,5-diformylfuran | A member of the class of furans carrying two formyl substituents at positions 2 and 5. | 2,5-diformylfuran |
| 2,5-dimethyl-1-(phenylmethyl)pyrrole-3,4-dicarboxaldehyde | | 2,5-dimethyl-1-(phenylmethyl)pyrrole-3,4-dicarboxaldehyde |
| 5-hydroxymethylfurfural | A member of the class of furans that is furan which is substituted at positions 2 and 5 by formyl and hydroxymethyl substituents, respectively. Virtually absent from fresh foods, it is naturally generated in sugar-containing foods during storage, and especially by drying or cooking. It is the causative component in honey that affects the presystemic metabolism and pharmacokinetics of GZ in-vivo. | 5-hydroxymethylfurfural |
| 5-sulfooxymethylfurfural | | 5-Sulfoxymethylfurfural |
| baldrinal | | Baldrinal |
| demethylzeylasteral | A carbopolycyclic compound with formula C29H36O6, originally isolated from Tripterygium wilfordii. | demethylzeylasteral |
| oncrasin-1 | A member of the class of indoles that is 1H-indole substituted by 4-chlorobenzyl and formyl groups at positions 1 and 3, respectively. It is an anti-cancer agent that is active against lung cancer cells with K-Ras mutations. | oncrasin-1 |
| piperonal | An arenecarbaldehyde that is 1,3-benzodioxole substituted by a formyl substituent at position 5. It has been isolated from Piper nigrum. | piperonal |
