yanuthones
A class of meroterpenoids whose core structure consists of 5,6-epoxycyclohex-2-en-1-one which is substituted by varying side chains at positions 3 and 4, and by a sesquiterpene chain at position 6. The core structure may be derived from 6-methylsalicylic acid, which due to a decarboxylation results in a C<small><sub>7</sub></small> scaffold (a 6-membered methylated ring); these are known as class I yanuthones. Class II yanuthones contain a C<small><sub>6</sub></small> scaffold derived from an unknown precursor.
