PD 168368 is a potent, competitive, and selective neuromedin B receptor (NMB-R) antagonist with the Ki of 15–45 nM[1]. PD 168368 is neuromedin B receptor (NMBR; IC50=96 nM) / gastrin-releasing peptide receptor (GRPR IC50=3500 nM) antagonist[2]. PD 168368 also is a mixed FPR1/FPR2/FPR3 agonist with EC50s of 0.57, 0.24, and 2.7 nM, respectively[3].

(In Vitro)

PD 168368 (PD168368) is highly active and stimulated [Ca2+]I release in human neutrophils with EC50 values in the nanomolar range[3].
PD 168368 (PD168368) suppresses migration and invasion of the human breast cancer cell line MDA-MB-231. PD 168368 reduces epithelial-mesenchymal transition (EMT) of breast cancer cells by E-cadherin upregulation and vimentin downregulation. PD 168368 (5 μM) inhibits migration and invasiveness in breast cancer cells[4].
PD 168368 (10 μM) suppresses the activation of mTOR/p70S6K/4EBP1 and AKT/GSK-3β pathways in breast cancer cells[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[4]

Cell Line: Human breast cancer cell line MDA-MB-231
Concentration: 5 μM
Incubation Time: 24 hours
Result: Clearly decreased the migratory ability of MDA-MB-231 cells in a Boyden chamber migration assay.

Cell Viability Assay[4]

Cell Line: MDA-MB-231 cells
Concentration: 10 μM
Incubation Time: 0, 0.5, 1, 2, 4, 8, and 16 hours
Result: Decreased phosphorylation levels of mTOR, p70S6K, 4EBP1, AKT and GSK-3β in a time-dependent manner.
(In Vivo)

PD 168368 (PD168368) potently inhibits in vivo metastasis of breast cancer. PD 168368 (1.2 mg/kg; intraperitoneal injection for 30 days) inhibits metastasis of breast cancer in mice[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female BALB/c-nude mice (age 8-10 weeks) bearing MDA-MB-231 xenograft model[4]
Dosage: 1.2 mg/kg
Administration: Intraperitoneal injection for 30 days
Result: No metastatic tumor nodules were observed in lungs of PD 168368-treated mice compared to PEG-injected mice.
