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.

Esterase-mediated synthesis of optically active GABA analogues containing a stereogenic all-carbon quaternary carbon atom
Esterase from Horse Liver (HLAP) was able to hydrolyze a series of linear and cyclic beta,beta-dialkyl-gamma-nitroesters, in spite of the well-known reluctance of hydrolytic enzymes to recognize and transform hindered substrates, such as those possessing a stereogenic quaternary carbon atom next to the reaction site. The resulting optically active gamma-nitroesters gave access to optically active beta,beta-disubstituted gamma-aminoacids as well as alpha,alpha-disubstituted succinic acids, both being biologically relevant compounds.
