Fluciclovine is a [18F]-tagged synthetic analog of the amino acid L-leucine. It presents excellent diagnostic properties to be used in positron emission tomography (PET) imaging. The structure of fluciclovine allows it to be uptaken by the tumoral cells by its amino acid transporter without incorporating in the metabolism within the body. Fluciclovine was developed by Blue Earth Diagnostics, Ltd. and FDA approved in May 27, 2016.
Fluciclovine is indicated as a detection agent for positron emission tomography (PET) in men with suspected prostate cancer recurrence based on elevated blood prostate specific antigen (PSA) levels following prior treatment. The overexpression of L-type amino acid transporters such as LAT1 and LAT3 that mediate the uptake of essential amino acids has been extensively reported as a tumoral mechanism of cell growth.
