Aromatic aldehydes

Gossypol () is a natural phenol derived from the cotton plant (genus Gossypium). Gossypol is a phenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes. It is a yellow pigment. The structure exhibits atropisomerism, with the two enantiomers having different biochemical properties.

Hydroxymethylfurfural (HMF), also known as 5-(hydroxymethyl)furfural, is an organic compound formed by the dehydration of reducing sugars. It is a white low-melting solid (although commercial samples are often yellow) which is highly soluble in both water and organic solvents. The molecule consists of a furan ring, containing both aldehyde and alcohol functional groups.

Pyridine-2-carbaldehyde, also called 2-formylpyridine, is an organic compound with the formula NC5H4CHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-3-carboxaldehyde and pyridine-4-carboxaldehyde.

Ascofuranone is an antibiotic produced by various ascomycete fungi including Acremonium sclerotigenum that inhibits the Trypanosoma brucei alternative oxidase and is a lead compound in efforts to produce other drugs targeting this enzyme for the treatment of sleeping sickness. The compound is effective both in vitro cell culture and in infections in mice.

chemical compound

Indole-3-carbaldehyde (I3A), also known as indole-3-aldehyde and 3-formylindole, is a metabolite of dietary which is synthesized by human gastrointestinal bacteria, particularly species of the Lactobacillus genus. I3A is a biologically active metabolite which acts as a receptor agonist at the aryl hydrocarbon receptor in intestinal immune cells, in turn stimulating the production of interleukin-22 which facilitates mucosal reactivity.

chemical compound

Pyridine-3-carbaldehyde, also known as nicotinaldehyde, is an organic compound with the formula C5H4NCHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-4-carboxaldehyde. It is a colorless liquid that is routinely available commercially. It can be produced from nicotinonitrile. Alternatively, it arises by the aerobic oxidation of the corresponding alcohol.
