Chemical compound
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 [ ]
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 .[5]
Its toxicity and carcinogenicity in humans are unknown.[5]
Eugeroic [ ]
A study published by Cephalon describing research to develop a successor to the eugeroic modafinil reported that the corresponding fluorenol derivative was 39% more effective than modafinil at keeping mice awake over a 4-hour period.[6] However, after further investigation it was determined that the eugeroic activity of the fluorenol analog was likely due to an active metabolite , which they identify as fluorenol itself.[6] Fluorenol is a weak dopamine reuptake inhibitor with an IC50 of 9 μM , notably 59% weaker than modafinil (IC50 = 3.70 μM),[6] potentially making it even less liable for addiction .[7] It also showed no affinity for cytochrome P450 2C19 , unlike modafinil.[6]
