| Description |
SHA 68 is a potent and selective non-peptide neuropeptide S receptor (NPSR) antagonist with IC50s of 22.0 and 23.8 nM for NPSR Asn107 and NPSR Ile107, respectively. SHA 68 has limited the blood-brain barrier (BBB) penetration and the activity in neuralgia[1][2].

| In Vivo |
SHA 68 (i.p.; 5 and 50 mg/kg) reduces NPS-induced horizontal activity and vertical rearing and climbing[1]. SHA 68 (i.v.; 1 mg/kg) has a T1/2 of 0.74 hours, a CL of 4.29 mL/min/kg, and a Vss of 2.53 L/kg[1]. SHA 68 (i.p.; 2.5 mg/kg) has a T1/2 of 0.43 hours, a CL of 4.56 mL/min/kg[1]. Animal Model: Male C57BL/6 mice age 8-12 weeks[1] Dosage: 5 and 50 mg/kg Administration: i.p. Result: Reduced NPS-induced horizontal activity and vertical rearing and climbing. Animal Model: Male C57BL/6 mice age 8-12 weeks[1] Dosage: 1 mg/kg (Pharmacokinetic Analysis) Administration: i.p. Result: Had a T1/2 of 0.74 hours, a CL of 4.29 mL/min/kg, and a Vss of 2.53 L/kg.
