| deguelin | A rotenone that is 13,13a-dihydro-3H-chromeno[3,4-b]pyrano[2,3-h]chromen-7(7aH)-one substituted by methoxy groups at positions 9 and 10, and by two methyl groups at position 3 (the 7aS,13aS-stereoisomer). It exists in abundant quantities in the bark, roots, and leaves of the Leguminosae family of plants and reported to exert anti-tumour effects in various cancers. | deguelin |

| rotenone | A member of the class of rotenones that consists of 1,2,12,12a-tetrahydrochromeno[3,4-b]furo[2,3-h]chromen-6(6aH)-one substituted at position 2 by a prop-1-en-2-yl group and at positions 8 and 9 by methoxy groups (the 2R,6aS,12aS-isomer). A non-systemic insecticide, it is the principal insecticidal constituent of derris (the dried rhizome and root of Derris elliptica). | rotenone |
| tephrosin | A member of the class of rotenones that is 13,13a-dihydro-3H-chromeno[3,4-b]pyrano[2,3-h]chromen-7(7aH)-one substituted with geminal methyl groups at position 3, hydroxy group at position 7a and methoxy groups at positions 9 and 10 (the 7aR,13aR stereoisomer). It is isolated from the leaves and twigs of Antheroporum pierrei and exhibits antineoplastic and pesticidal activities. | tephrosin |
