QX-314

QX-314 is a membrane-impermeable quaternary Lidocaine (HY-B0185) derivative with sensory-selective blocking effects. QX-314 inhibits acid-induced esophageal hypersensitivity. QX-314 enters jugular ganglion cells via TRPV1 channels, blocks NaV1.8 channels, and thereby inhibits esophageal sensory conduction. QX-314 can alleviate acid-induced esophageal inflammation. QX-314 can be used for the research on gastroesophageal reflux disease (GERD) [1].
