Review of Voltage-gated Calcium Channel α2δ Subunit Ligands for the Treatment of Chronic Neuropathic Pain and Insight into Structure-activity Relationship (SAR) by Pharmacophore Modeling

The latest progress in the discovery and development of gabapentinoids for the treatment of chronic NP was reviewed. Moreover, the structure-activity relationship (SAR) of gabapentinoids has been analyzed by pharmacophore modeling, which will be valuable for the future design of structurally novel therapeutic agents targeting the VGCC α2δ subunit.
