Fluorenol is an alcohol derivative of fluorene. In the most significant isomer, fluoren-9-ol or 9-hydroxyfluorene, the hydroxy group is located on the bridging carbon between the two benzene rings. Hydroxyfluorene can be converted to fluorenone by oxidation. It is a white-cream colored solid at room temperature.
Toxicity[edit]
Fluorenol is toxic to aquatic organisms including algae, bacteria, and crustaceans.[3] Fluorenol was patented as an insecticide in 1939,[4] and is an algaecide against the green algae Dunaliella bioculata.[5]
Its toxicity and carcinogenicity in humans are unknown.[5]
Wakefulness-promoting agent[edit]
A study published by chemists working for the biopharmaceutical company Cephalon to develop a successor to the wakefulness-promoting agent (or eugeroic) modafinil reported that fluorenol was 39% more effective than modafinil at keeping mice awake over a 4-hour period.[6] It is a weak dopamine reuptake inhibitor with an IC50 of 9 μM, notably 59% weaker than modafinil (IC50 = 3.70 μM) despite being a stronger wakefulness-promoting agent, potentially making it even less liable for addiction.[7] It also showed no affinity for cytochrome P450 2C19, unlike modafinil.[6]
