Mirogabalin besylate (DS 5565 besylate)

Mirogabalin besylate is a selective and orally available ligand for the α2δ subunit of voltage-gated calcium channels, with Kds of 13.5 nM, 22.7 nM, 27 nM, and 47.6 nM for human α2δ-1, human α2δ-2, rat α2δ-1, and rat α2δ-2, respectively.

Mirogabalin besylate is a ligand for the α2δ subunit of voltage-gated calcium channels, with Kds of 13.5 nM, 22.7 nM, 27 nM, and 47.6 nM for human α2δ-1, human α2δ-2, rat α2δ-1, and rat α2δ-2, respectively. Mirogabalin shows binding affinity for the gabapentin binding site in rat cortical brain homogenates with the IC50 value of 16.0 nM. Mirogabalin has no effect on any other receptors, channels, transporters, or enzymes at 50 μM[1].

Mirogabalin besylate (3 and 10 mg/kg) markedly increases AUC0-8 hours values in a dose-dependent manner in partial sciatic nerve ligation model rats. Mirogabalin (2.5, 5, and 10 mg/kg) causes significant and dose-dependent increase in AUC0-12 hours values and enhances analgesic effects, with estimated ED50 of 4.4, 3.1, and
