SHA 68(CAT: I010971) is a potent and selective non-peptide neuropeptide S receptor (NPSR) antagonist with IC₅₀ values of 22.0 nM (NPSR Asn107) and 23.8 nM (NPSR Ile107). It demonstrates limited blood-brain barrier penetration and has been evaluated for neuralgia-related activity. In vivo, SHA 68 (i.p.; 5–50 mg/kg) reduces NPS-induced locomotor activity, including horizontal movement, rearing, and climbing. Pharmacokinetic studies show rapid clearance and short half-life: SHA 68 (i.v.; 1 mg/kg) exhibits T₁/₂ of 0.74 h, CL of 4.29 mL/min/kg, and Vss of 2.53 L/kg, while (i.p.; 2.5 mg/kg) yields T₁/₂ of 0.43 h and CL of 4.56 mL/min/kg.
