| 4,5-dioxovaleric acid | A dioxo monocarboxylic acid consisting of a valeric acid core with the two oxo groups at the 4- and 5-positions. | 4,5-dioxopentanoic acid |
| acetylpyruvic acid | A dioxo monocarboxylic acid that is pentanoic acid carrying two oxo groups at positions 2 and 4. | acetylpyruvic acid |
| integric acid | An eremophilane sesquiterpenoid with anti-HIV-1 activity. It is isolated from Xylaria sp. MF6254. | integric acid |
| lucidenic acid n | A tetracyclic triterpenoid that is 25,26,27-trinorlanost-8-en-24-oic acid substituted by hydroxy groups at positions 3 and 7 and oxo groups at positions 11 and 15 respectively (the 3beta,5alpha,7beta stereoisomer). Isolated from the fruiting bodies of Ganoderma lucidum, it exhibits cytotoxicity against tumour cells. | lucidenic acid N |
| succinylacetone | A dioxo monocarboxylic acid that is heptanoic acid in which oxo groups replace the hydrogens at positions 4 and 6. It is an abnormal metabolite of the tyrosine metabolic pathway and a marker for type 1 tyrosinaemia. | 4,6-dioxoheptanoic acid |
| trimellitic anhydride | A 2-benzofuran compound having oxo groups at the 1- and 3-positions and a carboxy substituent at the 5-position; the cyclic anhydride formed from the carboxy groups at the 1- and 2-positions of trimellitic acid. | trimellitic anhydride |
