体外研究 (In Vitro) | SB-222200 inhibits125I-[MePhe7]neurokinin B (NKB) binding to CHO cell membranes stably expressing the hNK-3 receptor (CHO-hNK-3R) with a Kiof 4.4 nM[1]. SB-222200 antagonizes NKB-induced Ca2+mobilization in HEK 293 cells stably expressing the hNK-3 receptor (HEK 293-hNK-3R) with an IC50of 18.4 nM[1]. SB-222200 is selective for hNK-3 receptors compared with hNK-1 (Ki>100,000 nM) and hNK-2 receptors (Ki=250 nM)[1]. SB-222200 (10 nM-1 μM) produces a concentration-dependent, surmountable inhibition of NKB-induced Ca2+mobilization in HEK 293-hNK-3R cells[1].

体内研究 (In Vivo) | SB-222200 (5 mg/kg; 30 min pretreatment) produces inhibition of behavioral responses induced by NK-3 receptor-selective agonist senktide (HY-P0187) in mice[1]. SB-2222006 exhibits moderate oral bioavailability (rat 46%) and Cmax(rat 427 ng/mL) following oral administration (rat 10 mg/kg)[1]. SB-2222006 exhibits terminal elimination half-life (rat 1.9 h) due to high plasma clearance (56 mL/min/kg) following intravenous administration (rat 2.5 mg/kg)[1].
Animal Model: | Male BALB/c mice (19-21 g)[1] | Dosage: | 5 mg/kg | Administration: | Oral administration | Result: | Produced 57% inhibition of senktide-induced behavioral responses in mice. |
Animal Model: | Male Sprague-Dawley rats (300-400 g)[1] | Dosage: | 2.5 mg/kg for i.v.; 10 mg/kg for p.o. (Pharmacokinetic Analysis) | Administration: | Intravenous injection and oral gavage | Result: | Oral bioavailability (46%), T1/2(1.9 h), Cmax(427 ng/mL). |
