Alrestat was first synthesized in 1969 and was the first aldose reductase inhibitor (ARI) with oral bioavailability to undergo clinical trials, in the late 1970s and early 1980s. Low-quality trials and a high incidence of adverse effects (particularly hepatotoxicity) led to termination of its development, and it was never in clinical use.[3][4] It is structurally related to tolrestat, another ARI that was briefly marketed before being withdrawn in 1997.

Synthesis

edit

Alrestatin can be synthesized by the reaction of naphthalic anhydride with glycine.[5]
