6α-fluorotestosterone (6α-fluoro T) acts as a competitive inhibitor of aromatase cytochrome P450. The mechanism by which substitution of a fluorine at the 6 alpha-position interferes with the aromatization reaction remains to be determined, but the inhibitory action on estrogen formation may potentiate the androgenic properties of 6 alpha-fluorotestosterone in vivo due to a lowering of estrogen levels. Besides, 6α-fluoroT promotes male sex behavior, it does not promote mating by unassisted estrogen receptor binding and it does not promote mating via metabolism to another androgen.

Gentiobiose, α- (6-O-β-D-Glucopyranosyl-α-D-glucopyranose) is a rare disaccharide that was find in living systems which use it both structurally and as energy source. Gentiobiose was first isolated from gentian roots and was shown to be involved in signaling pathways of the plant.
