A number of unsubstituted aromatic hydrocarbons, azaheterocycles, oxaheterocycles and cyclic ketones were screened for their inhibitory potency towards monoamine oxidases (MAO; EC 1.4.3.4.) A and B. Fair activities (IC50 10-100 microM) and selectivities were found for, e.g. naphthalene, anthracene, phenanthrene

Microbial transformation of chromone, chromanone, and 3 ring A hydroxyflavones (5-hydroxy-, 6-hydroxy-, and 7-hydroxyflavones) was attempted using thirty-two microorganisms. While chromone was not biotransformed, chromanone was transformed to chromone and chromanol by Aspergillus niger in 2% yield. Ring A hydroxylated
