[C][C][Branch1][C][C][C][C@@H1][Branch1][#Branch1][C][C][=Branch1][C][=O][O][C][N]"}, {"from": "gpt", "value": "The molecule is a gamma-amino acid that is gamma-aminobutyric acid (GABA) carrying an isobutyl substitutent at the beta-position (the S-enantiomer). Binds with high affinity to the alpha2-delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues. It has a role as an anticonvulsant and a calcium channel blocker. It is functionally related to a gamma-aminobutyric acid."}]
