Structural and Computational Insights into the Mechanism of the Superior Pharmacological Activity of Crisugabalin: A Third-Generation Cavα2δ1 Ligand. (PubMed, J Chem Inf Model) - "Crisugabalin, a recently approved third-generation GABA analogue with a unique cage-like tricyclic scaffold, shows superior efficacy and safety over pregabalin and mirogabalin for treating neuropathic pain...Cryo-EM structures demonstrated crisugabalin's superior binding affinity for α2δ1 over gabapentin and l-leucine, driven by enhanced hydrogen bonding and hydrophobic contacts, alongside volumetric expansion of the l-leucine binding pocket...These findings establish the cage-like tricyclic motif as a novel pharmacophore that simultaneously optimizes binding entropy and enthalpy, providing a blueprint for next-generation voltage-gated calcium channel modulators. MD, τRAMD, and MM-GBSA used in this study are powerful computational tools for rational drug design, particularly for optimizing compounds with prolonged target residence times."

New Tricyclic γ‑Aminobutyric Acid Analogue HSK16149: A Ca2+ Channel α2‑δ Ligand for Treating Neuropathic Pain. (PubMed, ACS Med Chem Lett) - "Pregabalin and gabapentin are currently first-line treatments for neuropathic pain, but common adverse effects such as dizziness and somnolence frequently lead to treatment discontinuation. HSK16149 also demonstrated superior antihypersensitivity or antiallodynic/hyperalgesic effects compared to the commonly used pregabalin as the control and has the potential to minimize CNS side effects with good tolerability. Based on its exceptional preclinical characteristics, HSK16149 was chosen for further development to provide a more effective and safer drug for patients enduring neuropathic pain."

Safety and pharmacokinetics of a novel potent GABA analogue crisugabalin in Chinese subjects with various degrees of renal impairment. (PubMed, Br J Clin Pharmacol) - "For patients with GFR < 60 mL/min, dosage adjustments of crisugabalin should be considered. To maintain comparable plasma drug concentrations in patients with impaired renal function, it is recommended that crisugabalin doses be decreased by approximately 50% for every 50% decline in GFR."

Crisugabalin, a ligand for the α2δ subunit of voltage-gated calcium channels, exhibits no obvious abuse potential in rodents. (PubMed, Pharmacol Biochem Behav) - "Secondly, a rat drug discrimination study was employed to determine the pharmacological similarity between crisugabalin and the training drug midazolam. In the rat spontaneous withdrawal study, crisugabalin demonstrated a very low level of physical dependence. These findings suggest that crisugabalin has minimal to no potential for abuse, thereby establishing itself as a safer option relative to pregabalin and mirogabalin."
