DA-0218
DA-0218 is a Nav1.7 inhibitor. DA-0218 exerts state-dependent inhibitory effects. DA-0218 alleviates formalin-induced inflammatory pain behavior and Paclitaxel-induced mechanical hyperalgesia in mice. DA-0218 inhibits Histamine-induced acute pruritus and lymphoma-induced chronic pruritus in mice. DA-0218 can be used in research related to inflammatory pain, neuropathic pain, acute pruritus and chronic pruritus.

Nav1.7 |
In Vitro
DA-0218 (Compound 9) (0.01-10 μM; 14 min) potently inhibits Nav1.7-mediated sodium currents in HEK293 cells expressing Nav1.7, with an IC50 of 0.74 μM, and shows no activity against HEK293 cells expressing Nav1.5[1].
DA-0218 (10 μM) exerts a moderate inhibitory effect on transient sodium currents in human DRG neurons, reducing the peak current by 22% at 10 μM[1].
DA-0218 (10 μM; up to 14 min incubation and recording) inhibits the peak transient sodium current by 44% in small-diameter mouse dorsal root ganglion neurons pretreated with Paclitaxel (HY-B0015)[2].
DA-0218 (10 μM; up to 14 min incubation and recording) inhibits the peak transient sodium current of small-diameter human dorsal root ganglion neurons by 22%[2].

In Vivo
DA-0218 (10-30 nM; intrathecal injection; 10-30 mg/kg; intraperitoneal injection; single administration) transiently reverses paclitaxel-induced mechanical hyperalgesia in mice, but repeated administration leads to acute tolerance, and intraperitoneal administration shows no effect[2].
DA-0218 (intrathecal injection, 3-30 nM) inhibits Histamine (HY-B1204)-induced acute pruritus in mice[2].
DA-0218 (intrathecal injection, 30 nM) potently inhibits chronic pruritus induced by mouse lymphoma, with a duration of action of at least 5 h[2].

Formalin-Induced Paw Inflammation/Nociceptive Inflammation
The formalin-induced paw inflammation/nociceptive test is a chemical persistent pain model in rodents in which subcutaneous injection of formalin into the hind paw produces spontaneous nocifensive behaviors such as flinching and licking. The response is classically biphasic, consisting of an early acute phase (Phase I) reflecting direct activation of peripheral nociceptors (particularly C-fiber afferents), followed by a later prolonged phase (Phase II) associated with central sensitization in the spinal dorsal horn driven by sustained afferent input and inflammatory signaling. This model is widely used to evaluate analgesic and anti-inflammatory interventions because it captures both peripheral nociception and central sensitization processes within a single assay system.
