| 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.
