| 11-hydroxysugiol | An abietane diterpenoid that is sugiol in which the hydrogen ortho to the phenolic hydroxy group has been replaced by a hydroxy group. | 11-hydroxysugiol |
| ascochlorin | A dihydroxybenzaldehyde that is 2,4-dihydroxybenzaldehyde which is substituted by a (1E,3E)-3-methyl-1-[(1R,2R,6R)-1,2,6-trimethyl-3-oxocyclohexyl]penta-1,3-dien-5-yl group at position 3, chlorine at position 5, and a methyl group at position 6. A meroterpenoid produced by several fungi including Ascochyta viciae . It exhibits anticancer, antifungal and antiprotozoal activities. | ascochlorin |
| ascofuranone | A dihydroxybenzaldehyde that is 2,4-dihydroxybenzaldehyde which is substituted by a (2E,6E)-7-[(2S)-5,5-dimethyl-4-oxotetrahydrofuran-2-yl]-3-methylocta-2,6-dien-1-yl group at position 3, chlorine at position 5, and a methyl group at position 6. A meroterpenoid produced by the soil fungus, Acremonium sclerotigenum. It is a promising drug candidate against the tropical disease, African trypanosomiasis. | ascofuranone |
| austinol | A meroterpenoid produced by Aspergillus nidulans. It has a pentacyclic structure which incorporates three lactone functionalities and a spiro union. | austinol |
| berkeleydione | A meroterpenoid found in Penicillium rubrum. It has been shown to exhibit inhibitory activity against caspase-1. | berkeleydione |
| berkeleytrione | A meroterpenoid found in Penicillium rubrum and has been shown to exhibit inhibitory activity against caspase-1. | berkeleytrione |
| ferruginol | An abietane diterpenoid that is abieta-8,11,13-triene substituted by a hydroxy group at positions 12. | ferruginol |
| fumagillin | A meroterpenoid resulting from the formal condensation of the hydroxy group of fumagillol with the carboxylic acid group of (all-E)-deca-2,4,6,8-tetraenedioic acid. Originally isolated from the fungus Aspergillus fumigatus, it is used for the control of Nosema infection in honey bees. | fumagillin |
| liphagal | A meroterpenoid isolated from the marine sponge Aka coralliphaga and has been shown to exhibit inhibitory activity against phosphatidylinositol-3-OH kinase. | liphagal |
| novofumigatonin | | novofumigatonin |
| sugiol | An abietane diterpenoid that is ferruginol in which the methylene group para to the phenolic hydroxy group has been substituted by an oxo group. | sugiol |
