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. It does not have known toxicity or carcinogenicity in humans.
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. 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. It also showed no affinity for cytochrome P450 2C19, unlike modafinil. No human trials have yet been published as of 2014.
