Identification of Novel Ligands for the Gabapentin Binding Site on the α2δ Subunit of a Calcium Channel and Their Evaluation as Anticonvulsant Agents
摘要:
As part of a program to investigate the structure-activity relationships of Gabapentin (Neurontin), a number of alkylated analogues were synthesized and evaluated in vitro for binding to the Gabapentin binding site located on the alpha(2) delta subunit of a calcium channel. A number of other bridged and heterocyclic analogues are also reported along with their in vitro data. Two compounds showing higher affinity than Gabapentin were selected for evaluation in an animal model of epilepsy. One of these compounds, cis-(1S,3R)-(1-(aminomethyl)-3-methylcyclohexyl)acetic acid hydrochloride (19), was shown to be effective in this model with a profile similar to that of Gabapentin itself.

The present invention is directed to a method for the prophylactic and therapeutic treatment of diabetic retinopathy. The method involves the administration of an inhibitor of formulae (I), (II) and (III) of the branch chain amino acid-dependent aminotransferase (BCAT) pathway to an animal, such as a mammal, in particular a human, in an amount sufficient to treat the retina for diabetic retinopathy prophylactically or therapeutically. The present invention is also directed to several novel inhibitors of formula (IV) of the BCAT pathway. In formulae (I-IV), n, m, X and R1-R13 have the meanings given in the description.
